Description
COB stands for Chip on Board. The construction puts the chips on the board and covers them with a single phosphor film, so what you see lit is an even ribbon rather than a series of bright points.
6500K is the coolest option here — a clean cool white with a faint blue edge, showing colour much as daylight does.
24V DC · 480 chips/m · 7.5W/m · Ra>90 · 10mm × 2mm · IP20 indoor · cut every 50mm · 7-year guarantee
How much strip will one feed support?
Twenty metres at 24V. Two things allow it: a draw of 0.3125A per metre, 6.25A over the full length, and 3oz copper at 105 microns where most tape uses 35. Thin copper is why cheaper strip fades.
Which power supply suits it?
Calculate metres × 7.5W for the load, allow another 25%, then choose the next size up. The supply has to be constant voltage; constant-current units carry the same label but drive the strip badly and shift its colour.
Five metres wants a 60W supply, ten metres a 100W, and twenty metres a 200W.
Can it be trimmed to size on site?
It can. Cut lines fall on copper pads at 50mm spacing and a trimmed length performs as the reel did. The 150mm lead is attached. Unroll the whole run before powering it — heat builds inside a coil and is a fire hazard.
What does the IP20 rating exclude?
Every wet application. IP20 means no ingress protection, so this belongs indoors and dry: wardrobes, cabinets, display cases, coves. For bathrooms, outdoor runs or above a hob, choose IP67 instead. Confirm the internal channel of any profile you plan to use.
Which is whiter, 5000K or 6500K?
6500K. Where 5000K reads as clean neutral white, 6500K carries a slight blue edge and sits closest to midday light. Side by side the difference is obvious; alone, most people simply register 6500K as brighter, though output is the same.
- Right for: dressing rooms and wardrobes, display cabinets, retail, garages and workshops.
Lengths are cut to your specific requirement from a 20 metre roll before dispatch.

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).
