Didn't say they were fake, I said the numbers were bullshit. I didn't say they were bad or junk. But I hate companies that rig their data to sell more. Hell if these lights are good, a 2.5 would be a number to be proud of! Not many companies out there have hit above even 2.6 yet. And you...

Haven't looked into that actually, good question though!

Those numbers are bullshit. Ask them for there sphere test data from the testing company. I'll garantee you that MAYBE they'd hit 2.5, which is still quite good. Hell even Fluence doesn't claim these numbers! HLG Tested some of Chill LED's lights in a sphere test, and showed that their number...

Just starting to form fruits but the plants are the biggest and healthiest I've grown in the last three years! I'm hoping for a good crop! This was a week ago, they've grow a foot since then!

Get the 4.85 wide, it's actually cheaper than the 3.5 and has the disapation capacity you need. I built a light with a 40" slab of this running 6 Cree 2530 @ 40 watts each and it worked fine If I remember correctly heat at temp at the heatsink was 90F

Got 2 more Diablo boards! Can build my light now!

The bigger one was under four, QB 304

Sun powered! Dinafem White Widow XXL Autos. The small one was stunted as when I put her out here, it turned VERY cold, 2 nights in the 20's F days under 40! for about 3 days. The other was moved out here about 2 weeks ago, needed the tent for a photo period.

@CobKits I'm wondering if this is an error, doesn't make sense to me on driver selection seems backwards to me HLG480H-C2800 x3 QB648 Should be dimmed with this driver (???) HLG480H-C2100 x4 QB648

your right

actually, constant voltage drivers are used in series. Lets look at meanwell drivers. A 320H-C1400b driver is a constant Current driver. The voltages of the luminaires add up when run in series on this driver. This is why its important to read the data sheets for drivers. it can run up to 4...

The thing most people fail to get if they are shooting for max efficiency is that drivers are at their most efficient when driven to 90-100% of their rating, while boards are most efficient at low power. So the ideal build for efficiency would be to run one driver to its max and enough boards...

I use a pen, the tip fits right into that little dot on the lever.

It's the red LEDs, reversing polarity is blowing them out

SHHHHHHHHHH! I need two more weeks till I can get another pair!

Chem OG now under my QB 304 V1s. Going to transplant her tomorrow. The give her 2 more weeks and put her on 12/12.

Your current light gives you 40w/sq.ft. More than enough for a grow without CO2. As someone else said, go to a 2x4 and another HLG kit. Bang for the buck, you can't beat HLG, as they've got it all efficiency, spectrum, massive quantities of light and a fair price. Want a better light? you can...

Yeah, now they won't sell it DIY anymore..... and when I have the money I need 2 more......... :(

Scored a couple Diablo boards from cobkits!
