COB is the abbreviation of Chips on Board, which is the newest technology of packaging LED Chips. the LED Chips will direct contact with a substrate to produce LED arrays, the COB technology allows high density LED Chips than SMD(Surface Mounted Device) LEDs and dual in-line package LEDs, which allows a much higher quantity of LEDs per meter, not 30PCS, 60PCS or 120PCS, the COB LED Strips have at least 300PCS LED Chips per meter. this results in higher intensity and uniform light emission. this new technology can greatly reduce the footprint and energy consumption of LED arrays and keep light output constant.
now more and more customers like these new Strip Lights, which with more LEDs per meter, high CRI, high density, high brightness, uniform light emission, no light dots and no dark area, high efficiency and longer lifespan. you can use them for high-end lighting projects with any diffusers. they are 5meters per reel on the market, you can follow the cutting marks and cut to any length you want for your project, on our website, to avoid fewer issues, we can provide the length from 1meter to 5meters per piece.
there are various waterproof level products available, you can choose the IP30, IP67 and IP68, you can use the IP30 non-waterproof COB LED Strips in a dry place for indoor applications. the IP67 silicone tube waterproof LED Strips and IP68 glue injection Strip Lights for outdoor applications, you can install them in a wet, damp or water location. there are various emitting color products available, warm white, natural white, daylight white, red, green, blue, RGB and dreamcolor.
