What do you grow with?The best COB is one that is running the COBS the lowest amperage with many COBS.
Anywhere from .700 - 1400 is reasonable for efficiency. looking for around 900 PPFD in your grow space.
Optic runs the lights too high.
Light Brands: Pacific Light Concepts , Timber, Tasy COB Kits.
DIY is your best option. Talk to some folks around here and look at grows.
