haha texmexDepends if you're a MexiCan or a MexiCan't i guess. But i get your drift.

I’ll take a look. I should have over 1400 true watts. It’s supposed to be good for over 2000umol/s. I went with the 720w over the 660w so I can dim them a bit and set them right on top of the canopy. I’ll probably need CO2 to max them out. I’m not gonna go there until I actually fire these things up and collect the data.1000$ a little to take a pun on bro i cam in around 1100 on all three of mine which is around 420 true watts and i would say its killing a 1000w hps and a little more id say due to a few factors heat not being a issue also getting the lights bullshit close but check my thread out to were u would wanna be that light of urs would be killing my 2 150's and the ssk276 if it is what they say it is
dont dim ya lightsI’ll take a look. I should have over 1400 true watts. It’s supposed to be good for over 2000umol/s.

Bro, the FIXTURE itself nor it's "rating" has nothing to do with the diodes lifespan. Nothing at all. This is STRICTLY info that's in EVERY data sheet going as far back as CXA-3070 COBs from CREE.Alibaba L/90 lights? Really? I do not believe the claim as i saw recently on another skimpy bar light. No B ratings right? They are Not obligated to tell you that like say a Samsung made light from HLG is because it is made by Samsung.
Just because you bought the right size metal off Alibaba does not justify stating an Alibaba light is what it's claimed to be.
No offense bud.
I call BS.
Or do... Because 720w per 4x4 is really a Bit on the high side..dont dim ya lights
Not really I'm running 420in a 1.2Or do... Because 720w per 4x4 is really a Bit on the high side..
Fixed it.HLG and HGL are two very different companies, HLG is quality and HGL is a con women who phones the police on growers who don't praise her lights .
I'm sorry man but it works exactly the opposite. It has everything to do with the lifespan of the diode. Read the links man.Bro, the FIXTURE itself nor it's "rating" has nothing to do with the diodes lifespan. Nothing at all.

i found the more light the better i love a tennis ball sized nugOr do... Because 720w per 4x4 is really a Bit on the high side..
1.2m is 4'. So 720w is damn near double thatNot really I'm running 420in a 1.2

Never heard of diminishing returns?i found the more light the better i love a tennis ball sized nug
Really??? Lmfoa!!! Sorry dude but damn.@Chip Green @Rocket Soul @PSUAGRO. @Stephenj37826 @coreywebster @Gond00s @Rahz
Is this true? The info on these data sheets stating lifespan of diodes being 10% less bright at 50,000hrs has to do with the builds they're put on? Because I'm fucking POSITIVE none of these fixtures even from Alibaba are exceeding the reccomended Max tC°
Like I said, brother, I'm not accepting fixtures. Period.Really??? Lmfoa!!! Sorry dude but damn.
Thats what dictates an L rating assuming said binning. Now if you read the link you'd know this as well as the equally if not more important B-rating.
I’ve ordered from 4 different manufacturers on Alibaba and brought all of them to my buddy who used to be a Fluence rep. He basically told me the same thing you’re stating, heat management. I have a $279 light with lm301b diodes, 650w, it has a higher par reading than my Meijiu and my guy told me it’s basically a pos because of the heat management, I would be lucky if it would last 6 months. That’s why I decided to go with a light that has way more diodes on it at a lower wattage. In short, in my humble opinion I think heat management has alot to do with the lifespan of the lights!@Airwalker16 .
I understand where you are coming from. This is why Shanes test showed double the deportation then stated almost. Because they all built to the Diode data sheets.
The thermal mgmt, diode spacing & amount (more diodes well spaced), where the heat sink is placed, wire gauges, drivers, ect.. (build).
Reading the temp on the back of a sink tells you allot but not the whole story.
I hear a 40•f difference diode+sink compared to the norm will increase thr diodes lifespan or maintain output up 90% longer.
Funny cuz the Bar-8 is 40• cooler then everything else aside from actively cooled lights. 110-20• rather then (150-178•) some with far less diodes, others with tons.
Do you need the link again? I doubt anyone read it. Nobody ever wants to read what they don't wanna hear.
Also, every i told you is available through Google.
