Know before you buy
COB stands for 'Chip on Board.' Unlike traditional LED strips that have visible individual diodes, this technology uses a dense array of chips to create a seamless, continuous line of light without any hot spots or dotting.
Yes, the strip is designed to be cut every two inches. You can easily customize the length to fit your cabinets, coves, or shelving precisely.
This strip has an IP20 rating, which means it is intended for dry indoor locations only. It is not waterproof and should not be installed in areas where it will be exposed to direct moisture or water splashes.
Yes, because this is a 24V system, you will need a compatible 24V DC LED dimmer. Standard household wall dimmers designed for AC lighting will not work directly with this strip.
CRI, or Color Rendering Index, measures how accurately a light source reveals the true colors of objects. A rating of 90+ means this strip provides high-quality, natural-looking light, making it an excellent choice for task lighting where color accuracy matters.
The maximum continuous run length for this specific kit is 16.4 feet (5 meters). If you need to cover a longer distance, you will need to wire additional strips in parallel to the power supply rather than connecting them end-to-end.
