Quick decision summary: Need a clean, dot-free light line for kitchen pelmets or under-cabinet lighting? Start with 24V or 48V COB LED strip lights. Need colour-changing for hospitality or a feature wall? Choose RGBW COB LED strip lights. Need a run over 10 metres? 48V is the practical choice. Need outdoor or bathroom-rated LED strip lights? Check IP67 or IP68, not IP65.

Who this page is for: Electricians specifying LED strip lights for residential and commercial jobs, interior designers choosing strip lighting for kitchens and bathrooms, and homeowners researching LED tape lights before buying or hiring an installer.

Who this page is NOT for: if you need LED neon flex for signage or contour lighting, or aluminium profiles for mounting, those are separate collections, this page covers flexible LED strip tape only.

Common buying mistakes to avoid:

• Choosing IP65 for outdoor use: IP65 is surface-splash rated only and is not suitable for UK outdoor conditions or bathroom wet zones under BS7671 — you need IP67 minimum for outdoor and most bathroom zones.
• Buying a dimmable driver for RGBW strip: RGB and RGBW strips require a non-dimmable constant voltage driver paired with a dedicated RGB controller — dimmable drivers cause flicker, colour shift, and premature failure.
• Powering strip while still on the reel: Never power LED strip while coiled — the heat cannot dissipate, which destroys the adhesive backing and creates a fire risk.
• Mounting strip directly onto bare metal: Without insulation between the strip and the metal surface, you risk short circuits across the solder pads.

What are LED strip lights and which type do you need?

LED strip lights are flexible circuit boards with surface-mounted LEDs, available in COB (Chip on Board) and SMD (Surface Mounted Diode) formats. COB gives a continuous, dot-free line of light suited to architectural use; SMD gives individual LED points suited to signage and accent work. Both run on DC low voltage from 12V to 48V.

The biggest shift in LED strip lights since 2024 has been the move from SMD, where individual chips create visible hot spots, to COB, where densely packed chips sit beneath a phosphor layer for a smooth, unbroken line of light. For most 2026 residential and commercial installs, COB LED strip lights are the default recommendation because they remove the need for a diffuser channel.

• COB LED strip lights: Continuous dot-free line, 320–528 LEDs/m, ideal where the strip is partly or fully visible.
• SMD LED strip lights (2835/5050): Individual LED points with visible spacing, good for concealed cove lighting, signage backlighting, and budget jobs.
• Single colour LED strip lights: Fixed colour temperature (warm/natural/cool white) for task, ambient, or architectural lighting.
• RGBW LED strip lights: Four-channel strip with a dedicated white LED, so it produces both saturated colour and clean white.
• Addressable RGB LED strip lights: Individually controllable pixels for chasing effects and dynamic scenes.

ATOM LED stocks all of these from our Telford warehouse, with every COB strip rated CRI90+. Browse the full COB LED strip lights range to compare specifications.

COB vs SMD LED strip — which technology performs better in 2026?

COB LED strip lights outperform SMD in light uniformity, colour consistency, and visual quality for almost every architectural and residential application. COB removes visible hot spots without a diffuser; SMD strip still shows individual dots that need channel diffusion to look smooth.

Feature	COB LED Strip	SMD LED Strip (2835/5050)
Light output	Continuous dot-free line	Individual LED dots with visible gaps
Typical LED density	320–528 LEDs/m	60–120 LEDs/m
Diffuser required	Not required for most applications	Required to eliminate hot spots
CRI (ATOM LED range)	CRI90+ across all COB products	Typically CRI80–CRI90
Colour consistency	Excellent — phosphor layer blends output	Moderate — individual chips may vary
Flexibility	Higher — thinner PCB, tighter bending radius	Moderate — thicker PCB limits bending
Heat management	Requires aluminium profile for runs over 3m	Requires aluminium profile for runs over 3m
Best applications	Kitchen pelmets, coving, under-cabinet, display	Concealed coves, signage, budget accent
Price point (2026)	Approximately 15–30% higher than equivalent SMD	Lower entry cost per metre

Choose COB LED strip lights when the strip is visible, you need CRI90+ accuracy, or you're installing in a kitchen or bathroom. Choose SMD when the strip is fully concealed or the job is budget-led.

ATOM LED's dot-free COB LED strip lights in 24V and 48V are cut to length at marked intervals without voiding the 5-year warranty.

What voltage LED strip lights do you need — 12V, 24V, or 48V?

24V is the most versatile choice for residential LED strip lights up to 10 metres. 48V handles commercial runs up to 30 metres with half the voltage drop of 24V. 12V suits only short runs under 5 metres.

Specification	12V DC	24V DC	48V DC
Maximum single-feed run (single colour)	Approximately 5m	Up to 20m	Up to 30m
Maximum dual-feed run (single colour)	Approximately 8m	Approximately 30m	Up to 50m
Voltage drop rate	Highest — problematic over 3m at higher wattages	Moderate — manageable with correct wire gauge	Lowest — half the drop rate of 24V at same wattage
Current draw at 60W	5.0A	2.5A	1.25A
Wire gauge flexibility	Requires thicker cable	Standard 0.75mm² adequate for most runs	Thinner cable acceptable due to lower current
Safety classification	SELV with isolated driver	SELV with isolated driver	Falls within SELV threshold under BS7671 (120V DC ripple-free max) with suitably isolated, safety-rated driver
Best for	Short accent runs, legacy systems	Kitchens, bathrooms, residential, most commercial	Long commercial runs, retail displays, corridors

A hotel corridor needing four separate 24V feeds can often run on one 48V feed from a single end — less cable, fewer connectors, faster install.

• 12V: only for replacing existing 12V systems or accent strips under 3m — not recommended new in 2026.
• 24V: the residential standard — widest product and driver choice.
• 48V: built for runs over 10m, open-plan commercial spaces, retail perimeters.

Browse 24V LED strip lights for most residential jobs, or 48V LED strip lights for extended runs — both ship free from Telford.

What colour temperature is right for your LED strip lights?

Colour temperature sets the mood and function of your LED strip lights. Warm white (2700K–3000K) suits living areas and hospitality; natural white (3500K–4000K) suits kitchens, offices, and retail; cool white (5000K–6500K) suits workshops and clinical spaces.

Buyers often pick colour temperature by assumed brightness rather than the room's purpose, 3000K and 6000K produce the same lumens per watt, but perceived brightness differs.

• 2700K warm white: living rooms, bedrooms, dining rooms, hotel rooms.
• 3000K warm white: the most popular 2026 kitchen and bathroom choice.
• 4000K natural white: kitchen worktops, offices, retail — accurate rendering, no yellow bias.
• 5000K–6500K cool white: workshops, garages, inspection areas.

Every ATOM LED COB strip is CRI90+ — below CRI80, reds look muddy and skin tones grey, which shows immediately in a kitchen or on a retail shelf.

What IP rating do you need for bathrooms, kitchens, and outdoor LED strip lights?

IP rating determines where LED strip lights can be safely installed. IP20 is dry-interior only. IP65 handles surface splashes but is not suitable for UK outdoor conditions or bathroom wet zones under BS7671. IP67 withstands temporary immersion and suits most gardens and bathroom zones. IP68 handles continuous submersion.

The single most common UK spec error is using IP65 outdoors, it protects against a jet of water from one direction, not driving rain, standing water, or condensation.

• IP20: dry interior only, under cabinets, wardrobes, behind TVs.
• IP65: occasional indoor splashes only — not bathroom wet zones, not outdoors.
• IP67: outdoor gardens, patios, bathroom Zones 1–2, temporary immersion to 1m.
• IP68: ponds, fountains, ground-level, continuous submersion.

See the outdoor-rated LED strip lights collection (IP67/IP68, tested to UK conditions). Need help matching an IP rating to your bathroom zone? Call 01952 370028.

How do you dim LED strip lights without flicker?

Flicker-free dimming means matching the dimmer to the driver and strip type. For single colour LED strip lights, use a trailing-edge dimmer with a dimmable constant voltage driver — leading-edge dimmers cause flicker and buzzing. For RGBW/RGB, never use a dimmable driver — use a non-dimmable driver plus a dedicated controller handling PWM.

Swapping a leading-edge dimmer for a trailing-edge model (~£15) solves most domestic flicker complaints.

• Single colour: trailing-edge wall dimmer + TRIAC dimmable driver. Browse TRIAC dimmable LED drivers.
• RGBW/RGB: non-dimmable driver + dedicated LED controller.
• Smart dimming: MiBoxer, Skydance, and Ltech wireless controllers sit between driver and strip.
• 0–10V / DALI: commercial BMS-controlled installs.

Connecting RGBW strip to a dimmable driver is the most common call our Telford team gets, it shifts colour balance at low brightness. Always run RGBW/RGB drivers at full output and let the controller handle dimming.

How do RGBW and addressable RGB LED strip lights work?

RGBW LED strip lights combine red, green, and blue LEDs with a dedicated white LED, producing both saturated colour and clean white light. Standard RGB without a white channel can only approximate white, with a cold, violet-tinged result. Addressable RGB strip adds individual pixel control for chasing effects via SPI.

• RGB: three-channel, accent/decorative only — no clean white.
• RGBW: four-channel with a true white LED (3000K or 4000K) — suits kitchens and living spaces needing both colour and white light.
• Addressable RGB (SPI): individually controllable LEDs for water effects, chasing, pixel mapping.

All RGBW and RGB strips need a non-dimmable driver plus a dedicated controller — never a standard dimmer switch. See RGBW LED strip lights or addressable RGB LED strip lights.

What driver do LED strip lights need?

Every LED strip light needs a constant voltage driver converting 230V AC mains to 12V, 24V, or 48V DC, sized at least 20% above total strip wattage. Undersizing causes heat build-up and premature failure.

Example: 14.4W/m COB strip over 8m draws 115.2W — spec a driver rated ~140W or above.

• Constant voltage (CV) drivers: the standard type. Browse LED drivers and transformers.
• TRIAC dimmable drivers: for trailing-edge wall dimmer compatibility.
• Non-dimmable drivers: required for RGBW/RGB.
• IP-rated drivers: IP67 for outdoor/bathroom/damp locations.

How do you install LED strip lights step by step?

LED strip light installation follows the same core process regardless of voltage: measure, select the driver, prep the surface, cut, wire in parallel, test, then fix permanently.

1. Plan and measure the run; calculate total wattage; add 20% headroom; decide single- or dual-feed.
2. Select the driver and dimming method — match driver voltage to strip voltage exactly (a 24V strip on a 48V driver burns out instantly).
3. Prepare the surface — clean, dry, dust-free for the 3M adhesive; use an aluminium profile for runs over 3m; never mount on bare metal without insulation.
4. Cut to length — ATOM LED strip is cut to length at marked intervals without voiding the warranty.
5. Wire in parallel, never series — series wiring multiplies voltage drop, dimming the far end of the run.
6. Connect and test before fixing — check even brightness, correct colour, dimming, and controller function before adhering.
7. Apply and secure — peel adhesive in sections, press firmly, never power the strip while still coiled (fire risk).

Common LED strip light mistakes

Most LED strip light failures trace back to six causes: wrong IP rating, wrong driver pairing, series instead of parallel wiring, powering strip while coiled, mounting on bare metal, and undersized drivers. Each is preventable, and fixing them after install usually costs more than the strip itself.

• IP65 used outdoors: rated for splashes from one direction only — not UK weather. Use IP67 minimum outdoors, IP68 for ground-level or water features.
• Dimmable driver on RGBW/RGB strip: causes colour shift and flicker — always pair with a non-dimmable driver and controller.
• Series instead of parallel wiring: multiplies voltage drop, visibly dimming the far end of a run.
• Powering strip while coiled: heat can't dissipate — a documented fire risk that voids every warranty in the industry.
• Mounting on bare metal without insulation: exposed solder pads can short against a conductive surface.
• Undersized driver: running at or above rated capacity causes premature failure — always spec 20%+ headroom.

On voltage drop specifically: it's the visible dimming toward the far end of a run, caused by resistance in the copper PCB tracks. Doubling the voltage halves the current for the same wattage, which is why 48V LED strip lights show voltage drop at half the rate of 24V over the same distance. Mitigate it with parallel wiring, dual-feed (power from both ends), thicker cable gauge, or by choosing 48V for runs over 10 metres.

Need a voltage drop calculation for your specific run? Call 01952 370028, we do this daily.

How do you calculate voltage drop and maximum run length?

Voltage drop is the reduction in voltage along a strip run caused by the resistance of the copper PCB tracks. It manifests as visible dimming toward the far end of the strip. At 48V, voltage drop occurs at half the rate of 24V at the same wattage over the same distance, because the current is halved for the same power — this is the primary technical advantage of 48V for long runs in 2026.

The voltage drop formula for LED strip follows a simple principle: higher current through a given resistance produces greater voltage loss. Since power (watts) equals voltage multiplied by current, doubling the voltage halves the current for the same wattage. This means a 48V strip running at 14.4W/m draws 0.3A/m compared to 0.6A/m at 24V — and the I²R losses through the PCB copper are quartered.

• 24V single colour maximum single-feed: Up to 20 metres with ATOM LED COB strip, depending on wattage per metre — lower wattage strips allow longer runs before visible drop.
• 48V single colour maximum single-feed: Up to 30 metres — the reduced current draw means the PCB copper tracks carry half the load, and voltage drop accumulates at half the rate of 24V.
• 48V single colour maximum dual-feed: Up to 50 metres — feeding power from both ends of the strip effectively halves the maximum distance any point is from a power source.
• Mitigation strategies: Use parallel wiring, feed power from both ends (dual-feed), increase wire gauge on long cable runs, and choose 48V over 24V for any run exceeding 10 metres where voltage drop is a concern.

If you are planning a long commercial run — a retail perimeter, hotel corridor, or office open plan — and need help calculating the exact voltage drop for your specific strip and cable configuration, call our technical team on 01952 370028. We calculate this for customers daily and can confirm whether your planned run length will maintain even brightness from end to end.

Where are LED strip lights used?

LED strip lights are used across residential, commercial, and outdoor settings, with the right spec depending on voltage, IP rating, colour temperature, CRI, and run length.

Residential

• Kitchen under-cabinet/pelmet: 24V COB, 3000K or 4000K, CRI90+.
• Bathroom: IP67 for wet zones 1–2, IP20 for dry ceiling areas.
• Living room coving/TV backlight: warm white 2700K COB.
• Staircase/hallway: strip in aluminium stair-nosing profiles.
• Bedroom/wardrobe: low-wattage warm white, sensor-activated.

Commercial

• Retail display: CRI90+ essential; 4000K standard, 3000K for luxury/hospitality retail.
• Office: 4000K in ceiling coves and under-shelf positions.
• Hospitality: RGBW for switching warm-white service to colour-themed events.
• Museum/gallery: CRI90+ minimum for accurate artwork colour.

Outdoor

• Garden/patio: IP67 covered, IP68 ground-level or water-adjacent.
• Decking/pathway: IP67/IP68 in recessed aluminium profiles.
• Ponds/water features: IP68 only.

220V/240V AC mains strip must not be hardwired permanently in most UK residential installs, use 12V/24V/48V DC strip with an isolated driver.

FAQs about LED strip lights

These are the questions our technical team at ATOM LED answers most frequently from customers purchasing LED strip lights in 2026. Each answer is based on direct installation experience and UK electrical standards, not manufacturer spec sheets. If your question is not covered here, call 01952 370028 or email operations@atomled.co.uk.

1. Can I cut LED strip lights to any length?

ATOM LED strip is cut to length at marked intervals without voiding the 5-year warranty; standard strips restrict cuts to wider intervals (25mm–100mm).

2. How long do LED strip lights last?

30,000–50,000 hours (roughly 10–15 years at 8 hours/day), heat management via aluminium profile is the biggest factor in actual lifespan.

3. Do LED strip lights use a lot of electricity?

A 5m run of COB strip at 14.4W/m draws 72W, about 7.2p/hour at 2026 UK rates, versus 200–300W for equivalent halogen.

4. Can LED strip lights be used in bathrooms?

Yes, IP67 minimum for wet zones 1–2; IP20 is fine for dry areas outside the zones. IP65 does not meet BS7671 bathroom requirements.

5. What is CRI and why does it matter for LED strip?

Colour Rendering Index measures colour accuracy against daylight (0–100). ATOM LED's COB range is CRI90+; below CRI80, reds look muddy and food looks unappetising.

6. Is 48V LED strip safe to install?

Yes, 48V DC falls within the SELV threshold under BS7671 when supplied by a suitably isolated, safety-rated driver.

7. Can I connect multiple LED strip runs together?

Yes, in parallel — each run wires back to the driver independently. Avoid series wiring, which multiplies voltage drop.

8. What is the difference between LED strip and LED tape?

None — same product, different regional naming ("LED tape" is more common in UK trade).

9. Do I need an aluminium profile for LED strip?

Recommended for any run over 3 metres, and required above ~10W/m for proper heat management.

10. Can I use LED strip lights outside in the UK?

Yes — IP67 minimum for covered patios and gardens, IP68 for ground-level or water-adjacent installs. IP65 is not weather-rated for the UK.

11. What causes LED strip lights to flicker?

Most often a leading-edge dimmer (swap for trailing-edge, ~£15), an incompatible driver, a dimmable driver on RGBW strip, or an overloaded driver.

12. How do I choose between 24V and 48V LED strip?

24V for most residential runs under 10m; 48V for commercial or long runs over 10m, where voltage drop is half that of 24V.

13. What colour temperature is best for kitchens?

3000K warm white for ambient/under-cabinet; 4000K natural white for worktop accuracy. Avoid 5000K+ in residential kitchens, too clinical.

14. Does ATOM LED offer free delivery on LED strip lights?

Yes — free UK delivery on 97% of products, 1–3 working days from our Telford warehouse, UK stock only, never dropshipped.

15. Can I use LED strip behind a TV?

Yes — warm white (2700K–3000K) bias lighting at low brightness reduces eye strain from screen contrast.

16. What accessories do I need for LED strip installation?

Connectors (push-fit or solder), matching-gauge extension wire, and mounting clips, see LED strip accessories.
