What Are COB LED Lights?
COB LED lights are a new type of LED light quickly growing in popularity within the cannabis industry. COB stands for chip on board, and they offer a more robust spectrum of light.
A C.O.B. uses green light to boost the yields of indoor plants. COB lighting combines Cree COB with EpiLED technology. They expand on the beneficial spectrum found in white light by adding small amounts of green light. When compared to traditional LED grow lights, the COB LED lights have a full and wider spectrums that are very effective for indoor growing.
