Description
COB LED Strip 24 V – Dot-Free Line of Light with 512 LEDs/m
10 W/m · 900 lm/m · CRI > 90 · IP20 · 5 m reel · in five colour temperatures – select now
With 512 LEDs per metre this COB strip is among the densest we stock. The more diodes sit on one metre, the more finely they merge into a single line of light – and the more light comes out. At 900 lumens per metre it is bright enough to properly light work surfaces rather than just set a mood.

What does COB mean – and why are there no dots?
COB stands for chip on board and describes how the diodes are mounted. In a classic SMD strip, individual housed LEDs sit one to two centimetres apart on the board – you see them as a row of dots, especially when the strip lies close to a wall. With the COB principle, far smaller chips are placed directly on the circuit board and encapsulated together. At 512 chips per metre the individual light sources sit so closely that they merge completely for the eye.
512 or 320 LEDs per metre – which version fits?
Where is the difference to the version with 320 LEDs per metre? Two points: the line of light becomes a touch finer because the chips sit closer together – noticeable above all when the strip runs very close to a surface or is directly visible. And light output rises from 720 to 900 lumens per metre. For pure mood lighting the 320 version usually suffices; as soon as the light really has to brighten a surface, or the strip sits behind frosted glass, the denser version is the better choice.
CRI > 90: colours that are true
The colour rendering index describes how true colours look under a light source. The maximum of 100 equals daylight; anything above 90 counts as very good. This strip sits at CRI > 90 and therefore reproduces even fine gradations correctly – grain in wood, colour transitions in fabrics, the fresh colour of food. Precisely because COB strips often shine on goods or materials from a short distance, the high value shows here in particular.
Choose your colour temperature
- 2200 K extra warm white – 2200 kelvin sits at the warmest end of the scale and recalls candlelight or a dimmed incandescent bulb
- 2700 K warm white – the tone of a traditional incandescent bulb
- 3000 K warm white – the most chosen colour temperature for interiors because it feels warm yet stays crisp enough for practical tasks
- 4000 K neutral white – neutral white and renders colours with no warming or cooling tint
- 6000 K cool white – 6000 kelvin delivers the brightest and crispest light in this range
This strip is available in five colour temperatures. For living spaces and hospitality we recommend 2200 to 3000 K, for work areas and display cases 4000 K, and for workshops and technical applications 6000 K.
High-quality LED chips by Sanan
With a strip carrying 512 chips per metre – 2,560 on a 5 metre reel – consistency is everything. Even small manufacturing variations would show as a colour gradient along the length. That is why we use LED chips by Sanan Optoelectronics: the listed company from Xiamen is China's largest LED chip manufacturer and one of the three largest worldwide. Producing at that scale means sorting chips to very tight tolerances – and that is exactly what you see in the finished strip.
Choosing the right driver
The strip runs on 24 volt direct current and therefore needs a driver. Calculate like this: 10 watts per metre times 5 metres equals 50 watts for a full reel. A driver should not have to supply more than about 80 percent of its rated output continuously – so for one reel you need at least 65 watts. Sizing too tightly risks a unit that runs hot and fails early. We stock suitable drivers in accessories.
Installation, cutting and routing
The strip is fixed with the strong double-sided adhesive tape on its back; the surface should be smooth, clean and grease-free. You can shorten it every 50 millimetres at the marked points, where the contacts sit. Bending lengthwise is possible, sharp creasing is not – keep to a bending diameter of at least one centimetre, otherwise the conductor tracks may tear. Also run no more than 5 metres from one supply: voltage drops along the narrow copper tracks over distance, so a longer run glows visibly dimmer towards the end. With several reels, therefore, feed each one separately from the driver.

Applications
Thanks to its high light output this strip serves not only as mood lighting but as real illumination: under wall units above the worktop, in display cases and showcases, in ceiling coves as indirect main lighting, on shelves in retail fittings and in counters and furniture. At 8 millimetres wide and 2.3 millimetres high it fits common aluminium profiles. Important: the IP20 rating permits dry interior spaces only – it is not suitable for bathrooms, outdoors or damp rooms.
