At 48V the current is half that of a 24V strip at the same wattage, so voltage drop accrues at roughly half the rate over the same distance.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe copper helps too. Standard tape uses 1oz copper, 35 microns thick, and visibly dims past five metres. This uses 3oz, 105 microns — a third of the resistance. Together that is enough for a whole-room perimeter, a continuous cove, a long shelf line or a facade run in one unbroken length, without a mid-run power injection or a second driver hidden along the way. This is the strip to reach for when 24V tape would need splitting into sections.\u003c\/p\u003e\u003ch2 id=\"s2\"\u003eHow do you size the power supply?\u003c\/h2\u003e\u003cp\u003eMetres × 7.5W gives the load. Add 25% and round up — a supply run flat out has nothing left for inrush and dies early.

For a 50 metre dual-feed run, split the load across two supplies, one at each end.\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0500\/5315\/2935\/files\/cob-led-strip-10mm-dimensions-diagram-30m-run.webp?v=1787550040\u0026amp;width=2400\" srcset=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0500\/5315\/2935\/files\/cob-led-strip-10mm-dimensions-diagram-30m-run.webp?v=1787550040\u0026amp;width=800 800w, https:\/\/cdn.shopify.com\/s\/files\/1\/0500\/5315\/2935\/files\/cob-led-strip-10mm-dimensions-diagram-30m-run.webp?v=1787550040\u0026amp;width=1600 1600w, https:\/\/cdn.shopify.com\/s\/files\/1\/0500\/5315\/2935\/files\/cob-led-strip-10mm-dimensions-diagram-30m-run.webp?v=1787550040\u0026amp;width=2400 2400w\" sizes=\"(min-width: 1180px) 700px, 100vw\" width=\"2400\" height=\"525\" alt=\"10mm COB LED strip dimensions diagram 30 metre run 50mm cut points\" loading=\"lazy\" decoding=\"async\" style=\"margin:0 auto\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cem\u003eStrip layout — all dimensions in millimetres\u003c\/em\u003e\u003c\/p\u003e\u003ch2 id=\"s3\"\u003eDo you need an aluminium profile?\u003c\/h2\u003e\u003cp\u003eFor short accent runs on a clean, cool surface, the 3M backing alone is fine. For longer runs, enclosed coves, or anywhere the strip cannot shed its heat, mount it in an \u003ca href=\"https:\/\/atomled.co.uk\/collections\/led-strip-profiles\" target=\"_blank\" rel=\"noopener\"\u003ealuminium profile\u003c\/a\u003e — the channel acts as a heatsink, extends LED life and gives a clean finished edge. At 7.5W per metre, a run beyond about five metres in an enclosed space benefits from one.\u003c\/p\u003e\u003ch2 id=\"s4\"\u003eWhich dimmer works with a 48V COB strip?\u003c\/h2\u003e\u003cp\u003eDim it at the driver, never on the strip itself. Pair it with a dimmable 48V constant-voltage driver and dim that — most take a mains trailing-edge dimmer, and 0-10V or DALI models exist for controlled installs. A wall dimmer wired into the DC output will flicker the strip and can damage it. Single-colour white like this dims smoothly from full down to roughly 5%.\u003c\/p\u003e\u003ch2 id=\"s5\"\u003eCan you shorten it to fit a run?\u003c\/h2\u003e\u003cp\u003eYes — 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 and the adhesive lifts.\u003c\/p\u003e\u003ch2 id=\"s6\"\u003eIs it safe over a sink or hob?\u003c\/h2\u003e\u003cp\u003eNo. 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 an IP67 strip there. Profile channels vary, so measure the internal opening before ordering.\u003c\/p\u003e\u003ch2 id=\"s7\"\u003eIs 5000K too cool for a living space?\u003c\/h2\u003e\u003cp\u003eFor most living rooms, yes — 5000K reads clinical against soft furnishings. It earns its place where the light is working: garages, workshops, utility rooms, home offices and display cabinets, where accurate, bright detail beats warmth.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRight for: garages, workshops, utility and plant rooms, home offices, display cabinets, task benches.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eYour run is cut to the precise length you specify from a 50 metre roll. Thirty metres runs continuously from a single feed at one end, and fifty metres from a feed at each end, so the longest architectural runs stay in one piece rather than being broken into powered sections.\u003c\/p\u003e\u003cp\u003eStocked and dispatched from our Telford unit with free UK delivery, backed by a 7-year guarantee and a 30-day return window.\u003c\/p\u003e\u003cp\u003eNot sure on length or which driver to pair?
