The DC 12V 2W white Big Tube COB(chip-on-board) High Brightness Waterproof Injection Module With Diffused Lens is mostly used for decorating and inside advertising lightboxes to illuminate alphabets and brand logos. This item also includes a 3M Foam tape on the back, which will allow the buyer to attach it to the desired application location without the use of any additional tape. Chip-on-Board (COB) LEDs is actually an array of high-power LED that is created by placing many low-wattage (typically 0.5W or 1W) LED dies side-by-side on a circuit board. COB LEDs are brighter, consume less power, and output a higher quality beam of light compared to older LED.
