Description
COB stands for Chip on Board. The chips are bonded to the board itself and covered by a single phosphor layer, which is why the lit face shows one even band rather than the scalloping you see from spaced diodes.
4000K is the neutral point of the range. It renders colour honestly, which makes it the sensible choice above a worktop.
24V DC · 480 chips/m · 7.5W/m · Ra>90 · 10mm × 2mm · IP20 indoor · cut every 50mm · 7-year guarantee
Why does this one run further than most tape?
Because thin tape fades. Standard strip uses 1oz copper, 35 microns, and dims past five metres. This uses 3oz, 105 microns — a third of the resistance, holding twenty metres from one 24V feed.
How do you size the power supply?
Metres × 7.5W gives the load. Add 25% and round up — a supply run flat out has nothing left for inrush and dies early. It must be a constant-voltage type, never constant-current.
Worked through: 5 metres is 37.5W so take a 60W supply; 10 metres is 75W, take 100W; 20 metres is 150W, take 200W.
Can you shorten it to fit a cabinet run?
Yes — cut on any marked pad, spaced 50mm apart, and the shortened length behaves exactly as before. The feed end ships with a 150mm cable attached. Leave it unpowered until it is off the reel; coiled tape cannot shed its heat.
Is it safe over a sink or hob?
No. IP20 offers zero ingress protection, so keep it to dry interiors: cabinet undersides, coves, profiles, shelving. Steam, splashes and cooking residue all rule it out — specify IP67 there. Profile channels vary, so measure the internal opening.
Is 3000K or 4000K better for under cabinets?
4000K, in almost every kitchen. It shows raw ingredients, worktop stone and paint as they really are, where 3000K lays a yellow film across white surfaces. Choose 3000K only if the run is decorative rather than working light.
- Right for: under-cabinet and worktop task lighting, utility rooms, pantries, garages, workshops.
Your run is cut to the precise length you specify from a 20 metre roll.

Frequently Asked Questions
What is the difference between IP65, IP67, and IP68?
IP65 handles surface splashes only and is not suitable for UK outdoor conditions or bathroom wet zones under BS7671. IP67 is rated for temporary immersion and covers outdoor garden installations, most bathroom zones, and exposed architectural features. IP68 handles continuous submersion for ponds, fountains, and fully exposed outdoor applications. For most UK garden and decking projects, IP67 is the correct choice.
Can I cut this product to a custom length?
Yes. ATOM LED products can be cut at the marked cut points without voiding the warranty. Many competitors restrict cuts to 50–100mm intervals, which wastes offcuts on tight custom runs. Use sharp scissors or a craft knife for a clean cut, then seal the end with a suitable end cap.
What size driver do I need?
Multiply the total metres by the wattage per metre, then add 20% headroom. For example: 10 metres of 24V neon flex at 9W/m = 90W total, so you need a minimum 108W driver. Never load a driver above 80% capacity for long-term reliability.
Should I choose 12V, 24V, or 48V?
Choose 12V for caravans, cars, boats, and any project powered by a 12V battery. Choose 24V for most home and trade installs where you need dependable run length with lower voltage drop. Choose 48V for longer architectural runs where extra distance and single-feed flexibility matter. For underwater or submerged installs, use IP68 Waterproof lights and the correct driver for that product; do not use 48V underwater.
What is your warranty?
ATOM LED offers product-specific warranties: up to 7 years on single-colour COB strip, 5 years on RGB and RGBW COB strip, and 4 years on LED neon flex. The warranty covers manufacturing defects. Call 01952 370028 for warranty claims.
Do you offer free delivery?
Yes. Free UK delivery on 97% of products via Royal Mail 48-hour tracked. Free next day delivery on Mainland UK orders over £90 (order by 1pm, Mon–Fri).
