Hey that looks nice… I am running 2 SE5000 in one tent but wanted to do something different in the 4x4… Going with California Lightworks (2) solar system 550s with controller.
Total max output is 800 watts with 2… they claim it will replace 1200 watt hps. But at barely over 3amps each at max power they do run super efficient and “fairly cool” but you can hang them super high up. I have mine all the way up.
With the controller you can do auto sunrise and sunset and adjust the intensity and spectrum throughout the day so it pretty cool once you get it set up. I have some UVB lights for it also but they’re in my flower tent.
As far as real world light intensity and coverage, it seems to be as advertised. Here are some “unscientific” readings I took with lights max power.
12 inches below lights in trans lighting
30" below lights (at the top of canopy of my last two odd ball plants in need a place to finish)
30" below lights all the way over in left corner
48" below canopy level where the seedlings are. (a little shade from the two odd balls)
Obviously with just seedlings in there you could just run one and adjust accordingly but you can see you could run 100% without a controller.
This 3BOGxToof Decay has about 2 weeks left and will see how she finishes under these lights just running full spectrum. Not giving UVB as the seedlings are in the tent.
FYI… The light meter used Im not sure how good it is… But ive been using it over a year now and seems to be good for less than $200… Think I paid about 150. But for a meter that is not 500 bucks it does seem good quality.
