Soorry, I didn make it clear. When I choose LED, most people concerns power draw.Why?
For example, a MEIZHI 600W, power draw 260W, at round139.99USD, around $0.5/ture watt. Though a Chinese brand, solid build, beautiful look, strong output
I google everything and the statistics are from google and I agree it after feeling my plants[/QUOTE]
PAR map and PPFD on Meizhi sucks !!!!!
