6 39 watt HO T5=22,200 Lumens
1 150watt HPS=15,00 Lumens
Total 37,200 Lumens in 9 square feet
4133 Lumens per foot.
I have been thinking about more light. adding another 150watt HPs or just a 400watt HID. As you can see I got plenty of light and I would put money on this that it would rivel any 400wat HID system. out there.
Did yo see the video of the HPS light on the osilatinfg fan acting as a light mover? I know its funny but that should in creas the effiency of that light. Unfirtantly, I only had that idea the last two week of flower.
