Quick decision summary: If you are wiring a residential kitchen, bathroom, bedroom, or commercial bar/restaurant interior with runs under 15 metres, 24V neon flex is the right voltage — it offers the best balance of run length, dimmer compatibility, and driver availability in the UK market in 2026. If your runs exceed 15 metres or you are lighting a building facade, switch to 48V neon flex. If you need plug-and-play with no driver at all, see 220V/240V AC neon flex. If your project has an existing 12V DC leisure battery, 12V neon flex connects directly.

Who 24V neon flex is for:

• Residential kitchen and bathroom installers fitting under-cabinet, cove, or mirror-surround lighting with runs of 3–15 metres per feed point.
• Electricians and electrical contractors specifying LED neon flex for domestic refurbishments — 24V is the voltage most UK wholesalers stock drivers for.
• Bar, restaurant, and hospitality fit-out contractors installing accent lighting behind bar fronts, booth seating, and ceiling coves where individual runs rarely exceed 10 metres.
• Interior designers specifying neon flex for residential and boutique commercial schemes where CRI90+ colour rendering and smooth dimming are non-negotiable.
• Sign makers and display fabricators building illuminated lettering, logos, and channel signs using bendable neon flex profiles — see the neon sign making collection.

Who 24V neon flex is NOT for:

• Runs over 15 metres per feed. Voltage drop at 24V becomes visible past 10–15m depending on wattage. For 20–50m continuous runs, 48V neon flex is the correct choice.
• Campervan and marine projects with existing 12V batteries. Adding a 24V driver to a 12V system introduces unnecessary complexity. Use 12V neon flex instead.
• Building facades and architectural exteriors over 20 metres. These projects need 48V or 220V/240V AC for practical feed distances.

What is 24V LED neon flex and why is it the UK domestic standard?

24V LED neon flex is a flexible silicone-encased LED strip operating on 24V DC that produces a continuous, dot-free light line. It became the UK domestic standard because 24V balances three requirements simultaneously: run lengths up to 15 metres on a single feed, compatibility with trailing-edge TRIAC dimmers sold at every UK electrical wholesaler, and a driver price point (from approximately £18 for a 60W unit) that keeps project costs competitive against traditional lighting.

• Market position in 2026: 24V neon flex accounts for the largest share of UK neon flex sales across residential and light commercial sectors. Wholesalers including CEF, Edmundson, Rexel, and City Electrical Factors all stock 24V drivers as standard — 48V drivers require ordering in most branches.
• Voltage specification: 24V DC falls within the SELV classification under BS7671 (120V DC ripple-free maximum), provided the driver is suitably isolated and safety-rated. This means no Part P notification is required for the low-voltage wiring between driver and strip — though the mains supply to the driver must be installed by a competent person.
• Light output range: ATOM LED 24V neon flex delivers between 500 and 1,200 lumens per metre depending on profile size and LED density, with CRI90+ on all single-colour products.
• Profile options: The 24V range spans 4x10mm mini profiles (suitable for furniture and joinery details) through 8x16mm standard profiles (the workhorse for kitchens and coves) to 10x20mm architectural profiles (maximum light output for feature walls and facades).
• Colour range: Warm white (2700K, 3000K), natural white (4000K), cool white (5000K, 6000K), single colours (red, blue, green, amber, pink), RGB, RGBW, and addressable digital pixel — all available at 24V.

Where is 24V neon flex the right choice for your project?

24V neon flex is the right choice for any indoor or outdoor installation where individual runs sit between 3 and 15 metres, where dimming via a UK wall plate is required, and where the project is being wired from mains power via a DC driver. The three highest-volume applications in the UK in 2026 are residential kitchen under-cabinet lighting, bathroom mirror and cove lighting, and commercial bar and restaurant accent installations.

• Residential kitchens: Under-cabinet runs are typically 3–8 metres total. 24V neon flex in a 4x10mm or 6x12mm mini profile fits inside standard 18mm-deep kitchen pelmets. Warm white (3000K) is the most specified colour temperature for kitchen installations — it renders food naturally and creates a warm ambiance without the harsh clinical feel of cool white.
• Bathrooms: Mirror-surround and bath-panel cove lighting using IP67-rated 24V neon flex is the most popular bathroom LED application in UK residential refurbishments. Runs are typically 2–6 metres. IP67 minimum is required for Zone 1 and Zone 2 locations under BS7671 — IP65 is splash-only and not adequate for UK bathrooms where condensation is constant.
• Commercial hospitality: Bar fronts, booth seating, shelving, ceiling coves, and staircase handrails in restaurants, pubs, and hotels. Individual runs rarely exceed 10 metres, placing them comfortably within 24V range. RGB and RGBW variants (controlled via RGB controllers) allow colour-changing scene-setting tied to time of day or mood.
• Retail display: Shop window borders, product shelving, and POS display illumination where CRI90+ colour rendering shows merchandise in its true colours. A 6m window border run at 10W/m draws 60W — well within a single 80W 24V driver.
• Outdoor gardens (IP67/IP68): Path edging, raised bed borders, pergola outlines, and decking surround lighting. Runs of 5–12 metres are typical for UK garden installations. See outdoor LED neon flex and neon flex decking lights for outdoor-specific options.

How far can you run 24V neon flex on a single feed?

The practical maximum for 24V single-colour neon flex on a single feed is approximately 10–15 metres, depending on the wattage per metre. For RGB and RGBW, the limit drops to approximately 7–10 metres due to higher current draw per channel. Beyond these distances, voltage drop produces visible dimming at the far end — parallel wiring from the driver to each section solves this completely.

Product type	Typical W/m	Max single feed	Current draw per metre at 24V
Single colour 8x16mm	8–10W	12–15m	0.33–0.42A
Single colour 10x20mm	12–15W	10–12m	0.50–0.63A
Single colour 4x10mm mini	5–7W	15m+	0.21–0.29A
RGB 8x18mm	12–14W (all channels)	7–8m	0.50–0.58A
RGBW 10x20mm	16–20W (all channels)	5–7m	0.67–0.83A
Addressable digital pixel	14–18W	5–7m (data signal dependent)	0.58–0.75A

• Voltage drop at 24V vs 12V: At the same wattage per metre, 24V neon flex draws half the current of 12V. Since voltage drop is proportional to current, 24V exhibits approximately half the voltage drop of 12V over the same distance — that is the fundamental reason 24V supports longer single-feed runs.
• Parallel wiring: For any installation with multiple sections, wire each section independently back to the driver. This ensures every section receives full 24V at its input. Use 1.0mm² cable for runs up to 5m and 1.5mm² for 5–15m. The driver must be rated for the total combined wattage of all parallel sections.
• 20m single feed on COB strip: ATOM LED 24V COB LED strip — not neon flex — supports up to 20m on a single feed due to optimised conductor width. If you need 20m continuous without parallel wiring, consider 24V COB LED strip as an alternative, or step up to 48V neon flex.

Which UK trailing-edge dimmers actually work with 24V neon flex?

Trailing-edge dimmers are the correct dimmer type for 24V LED neon flex when paired with a TRIAC dimmable driver. The dimmers confirmed compatible with ATOM LED's recommended drivers in 2026 include the Varilight V-Pro, Crabtree trailing-edge modules, Hamilton Litestat trailing-edge dimmers, and the BG Nexus trailing-edge range. Leading-edge dimmers frequently cause flicker and audible buzzing — if you hear a hum, the dimmer type is almost always the problem.

• Varilight V-Pro (?"JP250): The most widely installed trailing-edge dimmer in UK residential properties. Minimum load 10W, maximum 250W. Compatible with TRIAC dimmable 24V drivers from ATOM LED's own dimmable driver range. Dims smoothly from 100% to approximately 5%. Costs approximately £15–£20 retail.
• Crabtree trailing-edge: Available in 1-gang and 2-gang configurations. Push-on/push-off operation with rotary dim control. Compatible with the same driver range. Widely stocked at CEF and Edmundson branches.
• Hamilton Litestat trailing-edge: Premium finish options (brushed steel, polished chrome, satin brass). Same trailing-edge TRIAC operation. Higher price point (£25–£40) but matches high-end interior schemes.
• What to avoid — leading-edge dimmers: Leading-edge (also called "triac forward-phase" or "standard") dimmers were designed for incandescent and halogen loads. They chop the leading edge of the AC waveform, which interacts poorly with the rectifier inside most LED drivers. Symptoms include visible flicker at low dim levels, audible buzzing from the driver, and in some cases, premature driver failure. Replacing a leading-edge dimmer with a trailing-edge unit typically costs approximately £15 and fixes the problem immediately.
• Smart dimming alternative: For app-controlled or voice-controlled dimming without a wall dimmer, use a MiBoxer Wi-Fi controller or Skydance LED controller connected between a non-dimmable driver and the neon flex. These provide 0–100% dimming via Tuya Smart Life, Alexa, or Google Home without any mains dimmer involvement.

What driver does 24V neon flex need?

24V neon flex requires a 24V DC constant-voltage LED driver rated at minimum 1.2 times the total wattage of the strip. For single-colour neon flex that will be dimmed, use a TRIAC dimmable driver paired with a trailing-edge wall dimmer. For RGB and RGBW neon flex, always use a non-dimmable constant-voltage driver with a separate RGB controller — never a dimmable driver, which causes flicker and colour shift on multi-channel products.

• Sizing formula: Total watts = (watts per metre x total metres) x 1.2 safety factor. Example: 8m of 10W/m neon flex = 80W x 1.2 = 96W minimum driver. Choose a 100W driver. The 1.2 factor prevents thermal stress from continuous 100% load operation, extending driver life from approximately 30,000 hours to 50,000+ hours.
• ATOM LED IP67 power supply (outdoor, non-dimmable): IP67 rated, resin-potted, rated for -40°C to +90°C ambient. Available from 40W to 600W. A 150W unit covers a 12m run of 12W/m neon flex with margin.
• ATOM LED TRIAC dimmable driver (indoor): Designed for trailing-edge dimmer compatibility. Available from 16W to 60W. For higher wattages, ATOM LED stocks constant-voltage drivers with TRIAC dimming input up to 200W.
• ATOM LED own-brand drivers: Available in 24V LED driver and TRIAC dimmable driver ranges. Priced from approximately £18 (30W) to £65 (200W). All carry manufacturer warranty.
• RGB/RGBW driver rule (non-negotiable): RGB and RGBW neon flex dim through their controller, not through the driver. The controller modulates each colour channel independently. If you connect RGB neon flex to a dimmable driver and a wall dimmer, you will see flicker at low levels, colour shift (typically towards blue as red and green channels respond unevenly to voltage reduction), and in some cases, the controller will cycle or reset.

How does 24V heat dissipation compare under enclosed aluminium profiles?

24V neon flex generates more heat per metre than 12V at the same lumen output because the higher-density LED arrays required for 24V's longer run lengths pack more diodes into the same linear space. Under enclosed aluminium profiles — where heat cannot escape via natural convection — this matters: 24V neon flex typically runs 5–8°C hotter than 12V equivalent in a fully enclosed channel. At 48V, heat is actually lower per metre because the same lumen output is achieved at lower current, reducing resistive losses.

• Why this matters: LED junction temperature directly affects lifespan. Every 10°C increase above the rated operating temperature reduces LED L70 lifespan by approximately 25%. A 24V neon flex rated for 50,000 hours at 25°C ambient may deliver only 37,000 hours at 35°C ambient — still over 12 years at 8 hours daily use, but a measurable difference.
• Aluminium profile as heat sink: Mounting neon flex inside silicone profiles or aluminium profiles provides passive heat sinking. The aluminium conducts heat away from the LED junction and radiates it along the full length of the channel. This is why profile-mounted neon flex consistently outlasts adhesive-only surface mounting.
• Enclosed vs open profiles: Profiles with snap-on diffuser covers trap more heat than open-top channels. For 24V neon flex at 12W/m or above, specify profiles with at least 15mm depth to provide adequate thermal mass. Shallow 8mm profiles can overheat at high wattages in enclosed ceiling voids where ambient temperature may already be 30°C+.
• 24V vs 48V thermal comparison: A 10W/m neon flex at 24V draws 0.42A per metre. The same lumen output at 48V draws 0.21A per metre. Since resistive heat (I²R) is proportional to the square of current, 48V generates approximately one quarter the resistive heat of 24V for the same light output. This is why 48V is preferred for high-wattage commercial runs where thermal management is critical.

Voltage	Current at 10W/m	Relative resistive heat (I²R)	Typical surface temp in profile
12V	0.83A/m	4× baseline	45–55°C
24V	0.42A/m	1× (baseline)	38–48°C
48V	0.21A/m	0.25× baseline	32–40°C

Which IP rating should you choose for 24V neon flex?

For dry indoor kitchens, living rooms, and bedrooms, IP65 provides adequate protection against incidental dust and splashes. For UK outdoor installations, bathrooms, and any location exposed to sustained moisture, IP67 is the minimum safe choice under BS7671. For ponds, water features, and submersible applications, only IP68 is suitable. IP65 is not outdoor-rated for UK weather conditions — this is the most common specification error in UK LED installations.

• IP65 — indoor dry locations: Kitchen under-cabinet (not directly above sinks), living room coves, bedroom headboard lighting, retail shelf displays. Surface splash protection only — not rated for sustained water contact or outdoor exposure to UK rainfall.
• IP67 — outdoor and wet zones: Garden paths, pergola outlines, outdoor wall features, bathroom Zones 1 and 2, commercial kitchen work areas, car wash bays. Rated for temporary immersion to 1 metre for 30 minutes — handles heavy UK rainfall, jet-washing splash-back, and bathroom steam/condensation.
• IP68 — submersible: Pond perimeters, fountain basins, swimming pool surrounds, drainage channel lighting, and any application where the neon flex sits in permanent contact with water. Rated for continuous submersion beyond 1 metre depth.
• Outdoor specification error to avoid: IP65 neon flex installed on an exterior UK wall will fail within 12–24 months. The silicone sheath on IP65 products is thinner than IP67, and the end seals are not pressure-rated. Driving rain, pooling water in profile channels, and freeze-thaw cycling in British winters all breach IP65 seals. Always specify IP67 minimum for any UK outdoor installation — the price difference is typically £1–£3 per metre.

How do you install 24V neon flex step by step?

Installing 24V neon flex involves selecting and mounting a suitable driver, measuring and cutting the neon flex to length, wiring from the driver to the strip with correct polarity, testing before final mounting, and sealing all connections to maintain the IP rating. A typical residential kitchen installation of 6–8 metres takes approximately 2–3 hours for a competent installer. The low-voltage (SELV) section between driver and strip does not require Part P notification, but the mains supply to the driver must be installed by a qualified electrician or competent person.

1. Step 1 — Size and position the driver. Calculate total wattage: watts per metre x total metres x 1.2 safety factor. Position the driver within 2 metres of the neon flex start point to minimise cable runs. For kitchen installations, the driver typically sits inside a cupboard or above a wall unit. Ensure adequate ventilation — drivers generate heat and need airflow. Never seal a driver inside an unventilated void.
2. Step 2 — Run the mains supply to the driver. This section is 230V AC and must be installed by a qualified electrician or competent person under BS7671. Wire the driver's AC input terminals (L, N, E) to a fused spur or dedicated circuit. A 3A fused spur is adequate for drivers up to 700W.
3. Step 3 — Measure and cut the neon flex. Measure the required length and cut at the marked cutting points on the silicone sheath (typically every 50mm on 24V products). Use sharp scissors or a craft knife. Cut between marks and you will disable the LEDs in that section. Apply a silicone end cap to the cut end immediately.
4. Step 4 — Wire from driver to neon flex. Connect the driver's 24V DC output (+V and -V terminals) to the neon flex input wires using 1.0mm² cable for runs up to 5m or 1.5mm² for 5–15m. Use screw terminals, Wago 221 connectors, or solder joints. Maintain correct polarity throughout — reversed polarity on single-colour will produce no light.
5. Step 5 — Test before mounting. Power on the driver and check for even illumination across the full length. Confirm correct colour temperature and verify no dead sections. Never power the neon flex while it is coiled — the concentrated heat damages the silicone and adhesive and creates a fire risk. Lay the neon flex out flat or loosely draped during testing.
6. Step 6 — Mount the neon flex. Press into aluminium or silicone profile for the cleanest finish and best thermal management, or use the supplied mounting clips at 150–200mm intervals. Do not mount directly onto bare metal without insulation — bare metal contact can cause short circuits through the neon flex's aluminium-backed PCB.
7. Step 7 — Seal all connections and test again. Apply adhesive-lined heat shrink to every exposed connection. For IP67 and IP68 installations, inject clear RTV silicone into all end caps and connection points. Power on and run for 30 minutes to confirm no overheating, no flickering, and even brightness. Measure driver output voltage with a multimeter — it should read 24.0–24.5V DC under load.

When should you choose 24V over 48V neon flex?

Choose 24V when your individual runs are under 15 metres, when you want to dim from a standard UK wall dimmer without a separate controller, when you need the widest range of driver options at the lowest cost, and when your project does not require commercial-grade long-run capability. Choose 48V when runs exceed 15 metres, when thermal management in enclosed profiles is critical, or when the project is a commercial facade or architectural linear installation.

Factor	24V neon flex	48V neon flex
Max single feed (single colour)	10–15m	20–50m
Voltage drop rate	Baseline	~½ of 24V at same wattage
Driver availability UK	Widest range — every wholesaler stocks them	Narrower range — specialist order at most wholesalers
Driver cost (100W example)	~£25–£35	~£35–£50
TRIAC dimmer compatibility	Excellent — trailing-edge dimmers work directly	Limited — fewer TRIAC dimmable 48V drivers available
Thermal efficiency	Good — adequate for most residential	Better — lower I²R heat at same output
Best application	Residential, hospitality, retail, sign-making	Commercial facades, architectural, long-run industrial
Price range (ATOM LED)	From £9.95/m	From £19.50/m

• The £15 driver question: A 48V driver costs approximately £10–£15 more than a 24V driver of equivalent wattage. For a residential kitchen with one 6m run, that extra £15 buys you nothing — 24V handles 6 metres comfortably. For a 25m commercial bar run, that £15 saves you the cost and complexity of parallel wiring at multiple feed points — 48V pays for itself.
• Dimmer ecosystem: The UK residential dimmer market is overwhelmingly built around TRIAC trailing-edge control of mains-side loads. TRIAC dimmable 24V drivers are plentiful and cheap. TRIAC dimmable 48V drivers exist but are fewer, pricier, and harder to source from UK wholesalers. If smooth wall-plate dimming is a project requirement, 24V is the path of least resistance in 2026.
• Future-proofing: 48V is gaining market share in the commercial sector year on year. If you are specifying a commercial project that may expand or require additional long runs in future, starting at 48V avoids a voltage change later. For residential, 24V will remain the dominant domestic voltage for the foreseeable future.

How long does 24V neon flex last and what warranty applies?

ATOM LED 24V neon flex is rated for 50,000 hours to L70, which equates to approximately 17 years at 8 hours of daily use. Real-world lifespan depends on heat management, driver quality, and environmental exposure. ATOM LED provides up to 4 years warranty across the product range — specific warranty periods vary by product line and are stated on each product page.

• L70 explained: The L70 metric means the LEDs will still produce 70% of their original brightness after 50,000 hours. They do not "burn out" like incandescent bulbs — they gradually dim. At 70% output, most installations are still functional and visually acceptable.
• Driver lifespan: In approximately 70% of LED installation failures, the driver fails before the LEDs. Cheap unbranded drivers introduce voltage ripple that accelerates LED phosphor degradation. ATOM LED drivers are independently rated for 50,000+ hours at full load, with a 5-year manufacturer warranty.
• Heat as lifespan factor: Mounting in aluminium profile extends lifespan by improving heat dissipation. Running 24V neon flex inside an unventilated ceiling void at 35°C ambient reduces L70 lifespan by approximately 25% compared to installation in open air at 25°C. For enclosed installations, specify profiles with adequate thermal mass.
• Outdoor degradation: UV exposure degrades the silicone encapsulation over 5–8 years on south-facing exterior walls. IP67 and IP68 products resist this better than IP65 due to thicker UV-stabilised silicone. In coastal locations, salt spray accelerates connector corrosion — use stainless steel mounting hardware and seal all electrical connections with marine-grade silicone.

What are the most common questions about 24V LED neon flex?

Buyers and UK electricians most frequently ask about driver sizing, trailing-edge dimmer compatibility, maximum run lengths per feed, IP rating selection for British weather, and the practical differences between 24V and 48V systems. The 14 detailed answers below reflect the questions ATOM LED's Telford technical team handles most often in 2026 on 01952 370028 and by email.

1. Can I connect 24V neon flex to a 12V driver?

• No — 24V neon flex requires a 24V DC driver. Connecting to a 12V driver will produce very dim or no light output and may damage the LED driver over time due to impedance mismatch.
• If you only have a 12V power source available, use 12V neon flex instead.

2. Is 24V neon flex safe to install without an electrician?

• The low-voltage wiring between the 24V driver and the neon flex is SELV and does not require Part P certification or a qualified electrician.
• However, the mains supply to the driver (230V AC) must be installed by a qualified electrician or competent person under BS7671. A fused spur connection is the standard approach.

3. What cutting interval does 24V neon flex have?

• Most 24V neon flex cuts at 50mm intervals, marked on the silicone sheath. Some high-density products cut at 25mm intervals.
• Check the product datasheet for the exact cutting interval — it varies by profile and LED density.
• ATOM LED products allow cutting at any point without voiding the warranty.

4. Can I use 24V neon flex in a bathroom?

• Yes — use IP67 minimum for bathroom Zones 1 and 2 under BS7671. IP68 for Zone 0 (inside the bath or shower tray).
• IP65 is not adequate for UK bathrooms — condensation and direct splash exposure will breach IP65 seals over time.
• The 24V DC SELV circuit presents significantly reduced shock risk, but correct IP rating and sealed connections remain essential in wet environments.

5. Does 24V neon flex work with Philips Hue or other smart home systems?

• Not directly — Philips Hue operates on a proprietary Zigbee mesh and does not control third-party 24V LED strips natively.
• For smart control, use a Zigbee-compatible 24V LED controller (MiBoxer Zigbee 3.0 range) that pairs with a Zigbee hub, or a Wi-Fi controller that works with Tuya/Smart Life, Alexa, or Google Home.
• ATOM LED stocks MiBoxer controllers compatible with Alexa and Google Home voice commands.

6. How do I choose between warm white and natural white for a kitchen?

• Warm white (3000K) creates a cosy, amber-toned light similar to halogen. It is the most popular choice for residential kitchens where the lighting serves ambiance and general task illumination.
• Natural white (4000K) produces a neutral, balanced light that renders colours more accurately. It suits dedicated food preparation areas, commercial kitchens, and spaces where precise colour vision matters.
• Cool white (6000K) is rarely specified for residential kitchens — it produces a clinical, blue-tinged light that most homeowners find uncomfortable for prolonged exposure.

7. Can I run 24V neon flex from a 24V battery?

• Yes — two 12V batteries wired in series produce 24V DC. This is common in larger motorhomes, caravans with dual-battery systems, and off-grid solar installations.
• Ensure the battery bank is regulated — unregulated output can spike during charge cycles, exceeding the neon flex's maximum voltage tolerance.
• For most domestic installations, mains power via a 24V driver is simpler and more reliable than battery operation.

8. What is the minimum bend radius for 24V neon flex?

• Minimum bend radius varies by profile: 4x10mm mini profiles bend to approximately 25–30mm radius. Standard 8x16mm profiles require 40–60mm. Architectural 10x20mm profiles require 60–80mm.
• Bending tighter than the specified radius strains the internal LED strip and can cause dark spots, cracking of the silicone sheath, or premature failure.
• For sharp 90-degree corners, cut and rejoin with a corner connector rather than forcing a tight bend.

9. Does 24V neon flex flicker on camera?

• 24V DC neon flex powered by a quality constant-voltage driver produces no flicker visible to cameras at any frame rate. DC power delivers continuous current — there is no 50Hz mains cycle to create pulsing.
• If you see flicker on camera, the cause is almost always a poor-quality driver with excessive output ripple, or a leading-edge dimmer introducing AC artefacts into the dimmed signal.
• For video production environments, specify ATOM LED drivers with less than 5% output ripple.

10. Can I daisy-chain multiple 24V neon flex strips?

• You can connect strips end-to-end, but the total length from driver to the end of the last strip must not exceed the maximum single-feed distance (10–15m for single colour, 7–10m for RGB).
• For longer total installations, use parallel wiring — run separate cables from the driver to each section rather than daisy-chaining.
• Parallel wiring eliminates cumulative voltage drop and ensures even brightness across all sections.

11. What happens if I overload a 24V driver?

• Quality drivers (ATOM LED branded) have overload protection — they will shut down or reduce output current to protect themselves and the connected strip.
• Cheap unbranded drivers may not have overload protection and can overheat, fail prematurely, or in extreme cases present a fire risk.
• Always size your driver at minimum 1.2x the total strip wattage. A 100W strip load needs a 120W minimum driver.

12. Is 24V neon flex suitable for outdoor signs and shopfronts?

• Yes — IP67-rated 24V neon flex is widely used for outdoor signage, shop window borders, and facade lighting where individual runs stay under 15 metres.
• For runs over 15 metres on a single feed (common on large shopfronts), step up to 48V neon flex to avoid multiple parallel feed points.
• All outdoor sign installations must comply with local planning regulations and may require an electrician for the mains connection.

13. Can I use 24V neon flex for stair nosing?

• Yes — 4x10mm mini neon flex profiles fit inside aluminium stair nosing channels. Each step typically requires 0.8–1.2m of neon flex.
• Wire each step in parallel from a single driver positioned at the top or bottom of the staircase. A 12-step staircase at 1m per step draws approximately 60–100W total.
• Use a motion sensor or Zigbee controller for automatic activation — this is a popular residential upgrade in 2026.

14. How do I calculate total driver wattage for multiple zones?

• Add the wattage of every section: (length in metres x watts per metre) for each zone. Then multiply the total by 1.2 for the safety factor.
• Example: kitchen under-cabinet (4m x 8W = 32W) + kitchen plinth (3m x 8W = 24W) + bathroom mirror (2m x 8W = 16W) = 72W x 1.2 = 86.4W. Specify a 100W driver.
• If zones require independent dimming or colour control, each zone needs its own driver and controller. A single driver can only serve zones that dim and switch together.
