Fixed-interval strips force a cut back to the nearest solder pad, leaving a dark tail on a 780mm floating shelf.

A 342mm alcove shelf takes a 342mm length, not a 300mm one with a dead 42mm tail. Measure the shelf underside, cut, and the lit line reaches both ends with nothing wasted and no unlit gap where the shelf finishes.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eShelving rarely arrives in tidy multiples. Bookshelf bays and the tiers of an open shelving unit differ by a few millimetres, and a standard strip makes you round each one down. At 340 LEDs\/m the light stays dot-free, so a freshly cut end reads the same as the rest of the run.\u003c\/p\u003e\n\n\u003ch2\u003eHow do I fix the strip to a shelf underside?\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eClean the shelf underside with isopropyl alcohol, then press the adhesive backing along a pencil line 15 to 20mm behind the front edge. Over 2 metres, or on any metal shelving unit, mount it inside an aluminium profile. The strip must never sit on bare metal without insulation.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat:\u003c\/strong\u003e unwind the full length before powering it, never while it is coiled on the reel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver:\u003c\/strong\u003e size a constant voltage 24V driver roughly 20% above load, so a 3 metre run at 27W wants a 36W unit from our \u003ca href=\"\/collections\/led-drivers\"\u003e24V driver range\u003c\/a\u003e.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSight line:\u003c\/strong\u003e a shallow \u003ca href=\"\/collections\/led-strip-profiles\"\u003ealuminium profile\u003c\/a\u003e with a frosted diffuser hides the board from anyone seated below.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhich colour temperature suits display shelving?\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eUse 2700K or 3000K on living room shelving, books and ceramics, where warm white keeps timber and paper looking natural.
