That's classified. I could tell you but then I'd have to kill you.
I'm curious as to why are you curious. What's the goal? Are you considering a build?
lol there's a lot going on up in my head
but ya that's one reason.. I have a 7x7 space (four 3x3 squares, with 1 foot aisle space in between) that is due for an upgrade...
I built a few qb lights, which are currently lighting 1 quadrant of the space; the remaining 3/4 is lit by blurples (decent 2014ish versions with lots of white diodes mixed in with the red, blue & violet, but prob only equal to a se hps in efficiency or worse lol..)...
I'm ready to send the blurples on their way though and upgrade the lighting to something more efficient (same amount of light for less W and with less heat, rather than more light for same amount of W and heat.. if that makes sense... I in other words, I don't need more light in the space, just less heat and a lower power bill).. and honestly I just want the light to be all warmish to neutralish white because it's so much easier on my eyes and I just want to be able to wear regular shades in there not green ones
...
I've decided to move the three qb lights I built (each currently has 2 3500K qb288s on slate 3 triple heatsinks driven in parallel by HLG-320H-54A drivers) to 3 2x4 tents, giving me 24 sqft of extra space at up to 40W per sqft .. or move all 3 to a 4x4 and drive all 3 with only 2 of the drivers, giving me only 16 sqft of extra space at up to 40W per sqft but with more uniform coverage and greater efficiency...
which leaves me to light the 4 3x3 quadrants of the main space... I'd like to just go with 4 of the same thing, whatever I decide to do... here's all the possibilities I'm considering (in no particular order.. no preference yet, just trying to do a proper analysis before deciding):
- 2 x 1000w de hps (revolution micro deva, on light movers, dimmed to 60%)
- 4 x 315w cmh
- 8 x 260w qb288 kits (2 per 3x3, dimmed to ~157.5W each)
- 4 x 315w qb288 diy lights (just like the ones I already built, but with the better slate 2 heatsinks)
- 4 x 315w qb120 diy lights (each consisting of 6 qb120s, dimmed to ~52.5W each)
- 4 x 315w photonfantom diy lights (each consisting of 4 sun boards, fusion boards, or wavy boards at ~79W each)
- 4 x 400w timber 4vs (dimmed to ~315W each)
basically I want to keep the wattage constant (~315W per 3x3 quadrant) and analyze the PAR/$ of the various options, irrespective of other factors such as light uniformity, potential bulb changes, spectral differences, etc.... I just want to figure out the PAR/$ of all the possibilities I listed and I can then make my decision, taking all those other factors I mentioned into consideration.... if that makes sense...
