Natural White 4000K COB LED Strip 24V 10mm 480LEDs/m IP20 20m Run

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 · 714 lm/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. Twenty metres runs continuously from a single feed at one end with no visible fall-off in brightness.
