Any efficiency test yet?

I don't have a par meter...only a phone app called Phontone.....It's good for reference.. as in I can compare with what my existing name brand lights did. My Bestva 200w lights put out around 400 to 500 par at 24"....this thing was 600 to 700 with highs of 800 at 34" and a much more even distribution. It draws 830w down to 60w off dimmer.

To me this fixture is maybe a bit over powered for its size, it fits perfect for a 4x4 and 800w is more of a 5x5 powerlevel. Is there anyway you could check at what wattage you would get a solid 800 par at 10-12" height? Should be somewhere near 500w i guess.

Get a small clip fan dedicated to blowing on the driver, IMO that should really help with the life of the fixture. Can't wait to see what kind of results you pull under this light, it's a nice looking fixture and for the price DAMN! Best of luck, man

Photone or PPFD meter app should be pretty fine to get a good guess.

I would, deffo question the even distribution you just mentioned.
At 34" im almost certain you're killing your efficiency and lose alot towards your corners.
In a huge room that wouldn't be too much of a problem hanging the lights high compared to a tent.
In a tent you easily bounce around photons by hitting the walls.
I would hang them as low as possible, imo @ 18-20"

First pic was the 18th, first day under new light. Second is today. I'm leaving the light higher because their neglected early life left them a little tight. I want them to spread a bit between nodes to get better penetration for buds. They seem to be growing around an inch a day....

I agree I could lower it and turn it down, but part of the test is degradation and that will best show itself at full tilt.

Already done!....this thing runs pretty cool though...dual 400w drivers instead of one hot 800w seems to help.

The problem is with my phone app the "par" reading for me is only good for reference and kind of ball park....but I would guess closer to 400w at 12", this things bright. 800w works out to 50w/sq ft....maybe on the high side, but I couldn't buy a better 700w light for twice the money....sooo

That will show itsself over time anyways, brother.
I'd be kicking myself wasting over 200w in a 4x4, for no advantage.
On the contrary side, you're actually taking away from your lifespan.

That's exactly why I put four 220w panels in my 5x5 and run them at 550w.
Spread + coverage is awesome, corner pars are rockin and they will likely last for a pretty long time, even tho they were ultra cheap.

Agreed, I bought 2....I was ask by a few to test it, so I'm running to TRY to make it degrade lol. Just worked out my grow needed it too.

Just do 10 measurements real quick with your phone 4 in the corners and 6 inbetween, would ya?
I wanna know how efficient this is at least ballpark.
:clap:

At 16" I get 503 in the corner 780 mid way down 538 in far corner(door was open) Get a high of 1038 and 800/900's every where else. I would say thats within a couple hundred par + or _
