COB stands for “chip on board”, and it’s called that because of the construction of the diodes. Each diode contains many tiny, low-wattage chips that shine together to give you a super charged light out of a single diode.
50w COB diodes, for example, usually have fifty mini 1w chips on one small surface, giving you around anywhere from 3000 to 5000 lumens out of a one diode. That’s right — the same intensity you’d get out of a fifty 1w chips on a larger panel, you can get out of one COB diode. It will take fewer COB diodes to give you the same lumens as a spread or traditional panel, which means you can get high-powered COBs in much smaller sizes than other LED grow lights.
While they offer crazy intensity, the issue with COBs lies within their limited spectrum availability. These are available primarily warm 3500k spectrums and cool 6000k spectrums, but nothing in the way of multi-colored wavelengths, IR, or UV spectrums. However, if you’re looking for a grow light with huge intensity out of a small light, COBs are the way to go.
