HV9761-IP20-528-4K - 12w IP20 24v DC 4000K Free Cut COB Dotless LED Strip

12w IP20 24v DC 4000K Free Cut COB Dotless LED Strip

This is a general-purpose LED strip, the density most jobs actually want. It is bright enough to work under a cabinet or along a stair, and restrained enough to sit in a cove without turning it into a light box.

It is also the density that makes a diffuser worthwhile rather than optional. Bright enough that individual LEDs read as dots when uncovered, not so bright that a diffuser wastes what it produces.

Output and colour

This strip draws 12W per metre, producing 1150lm per metre.

⚠ Both figures are per metre, not per reel. A long run multiplies them, and that is the number that decides the driver.

It is a 4000K product - one fixed colour temperature.

This is a neutral white - the middle ground, and the safest choice when a space has to do several jobs. It keeps whites looking white without the coldness of a daylight source, which is why it suits kitchens, bathrooms and workspaces that also have to feel liveable.

It is also the easiest colour temperature to mix with existing lighting, because it sits between the warm lamps in most living spaces and the cooler light of task fittings.

Colour rendering is > 80 OR >90 CRI, which describes how faithfully colours appear under the light. It matters most where the lighting falls on food, skin, timber or fabric.

The beam spread is 120°.

Where it can be installed

⚠ At IP20 this has no moisture protection. It is for dry interior positions only - inside joinery, a cove, or a ceiling recess.

Bathrooms, kitchens near a sink, and any outdoor position need a weatherproof rating instead. An IP20 strip in a damp position fails at the circuit board, and it fails patchily rather than all at once.

Powering it

This strip runs at 24V DC, so it needs an LED driver between it and the mains. It cannot be connected to mains directly.

Size the driver from the run, not the reel: multiply the wattage per metre by the metres you are actually installing, then choose a driver comfortably above that total. A supply working at its limit runs hot, and heat shortens both the driver and the strip.

⚠ The driver's output voltage has to match the strip. Connecting 24V strip to the wrong supply either leaves it dark or destroys it, and that is not a warranty claim.

Cutting and installing it

Strip is cut to length at the marked cutting points only. Cutting between them severs the circuit and kills everything past the cut, so plan the run to the nearest marked point rather than to the exact millimetre.

Run it in an aluminium profile. The aluminium draws heat away, which is the single biggest factor in how long a strip holds its brightness, and the diffuser turns the line of separate LEDs into a continuous one.

Test the run before committing it. Adhesive backing does not survive being lifted and re-laid well, and a fault found after the diffuser and end caps are on means taking the whole run apart.
