Hi there, interested in building some led light bars, for a 4x8 table. 32 plants on the table. would like to use 32 led cob chips, one for each plant.

Im currently using 3 825 watt chinese panels (825 watt real draw verified with killawatt, 9x64x3w per panel) as you can see i use alot of light. DO you have some suggestions?> thanks

Hi there! I was impressed from your posts so i was hoping you could help me with some stuff.
I need some formula that could help me convert PAR mMols to lumens and if u can tell me some Chinese equivalent to the CREE CXA3070?
I'm in the middle of prototyping a product that uses LED to grow plants so i need low-price COBs for the RND process.
Thanks in advance :)
