LED Strip Lights for Commercial and Architectural Projects

Nothing technical — two names for the same product. "Tape light" is more common in North American specifications and "strip light" in the UK and Europe, but both mean a flexible PCB with surface-mounted LEDs and adhesive backing. It only causes trouble when a drawing set mixes both. More detail in the LED tape light guide.

Run length decides it. At equal power, 24V draws half the current of 12V, so losses along the copper are much lower and the far end of a long run stays as bright as the feed end. 24V is the default for continuous architectural runs; 12V still suits short cabinet and display runs. Most Senfey strips come in both — full comparison in the 12V and 24V LED strip lights guide.

Yes, but only at the printed cut lines. The strip is built from repeating circuit segments and each must stay complete to work, so the marks sit between segments beside the solder pads. That segment length — the cut increment — depends on density and voltage, so a 24V high-density strip cannot be trimmed as finely as a 12V standard one. Where exact lengths matter, we cut and terminate at the factory.

Multiply the watts per metre by the total metres on that circuit, then add roughly 20% headroom. A 60W load belongs on a driver rated near 75W — a supply held at full rating runs hot and its life shortens. Senfey stocks DC12V adapters from 12W to 96W; wiring and driver selection are covered in the LED strip connectors and power supplies guide.

The strip is dimmable; whether the installation dims properly depends on the dimmer and driver working together. A constant-voltage strip needs a dimmer designed for DC LED loads — a mains dimmer for incandescent lamps will flicker or fail. It must also match the channel count: one for single colour, three for RGB, four for RGBW, five for RGBCW. See the dimmable LED strip lights guide.

RGB produces white only by combining all three channels — acceptable as an effect, poor as functional light. RGBW adds a dedicated white die, so real white and colour come from the same strip. RGBCW adds a fifth channel, splitting white into warm and cool so colour temperature can be tuned. More channels means a wider board, which is why RGBW and RGBCW strips are 12 mm rather than 10 mm. Options are in the RGB LED strip guide.

Not as supplied. Catalogue SMD strips are IP20 — no protection against water — so they are indoor products. Outdoor and wet-area projects need a sealed version, built to order rather than stocked. For genuinely exposed work, LED neon flex is often better: it is manufactured with an integral sealed jacket rather than sealed afterwards. See the waterproof outdoor LED strip guide.

Because the distance between strip and diffuser is too small for that strip's pitch. Every SMD strip has a minimum depth at which a diffuser blends the points into a line; below it the individual LEDs reappear as scalloping. Three fixes: deepen the channel, raise the density, or change to a COB LED strip, which has no visible dots at any depth. Where the joinery fixes the profile, only the last two remain.

Yes. Senfey is a manufacturer supplying distributors, contractors and lighting specifiers rather than retail channels. Private labelling, custom reel lengths and custom packaging are available for resellers carrying their own brand. Buyer-side considerations are in the LED strip manufacturer and supplier guide.

On a standard SMD strip the whole circuit behaves as one unit — no way to light one metre and leave the next dark. An addressable strip adds driver ICs and a data line, so each pixel receives its own instruction, which is what makes chases, gradients and zoning possible. It costs more and needs a controller speaking the right protocol. For movement see addressable LED strip; for a steady even line a standard LED strip light is cheaper and more robust.
