Not just for kicks ....
Last nite , i was ripping on some Tangie OG ( love that shit BTW ) ....
Well after my chill on ... Kevin Costner walked thru my fucking wall , looked at me and said : " if you build that shit , they will cum ! " .....
I looked at him and said " Cum or Come " ? ...... He smirked and hit the bong a few times , then turned into a fucking unicorn an hopped his ass out the window.
So i mocked up the build ..... True story

Booo I thought it meant that one elusive babe that no matter what you just can't have (but she is super fine)

LOL! I like your version better.
Someone....PLEASE... post some buds flowering under a QB.
I want to do a side by side with a DIY COB versus a QB board.

Got some flowering going on with QB - Blue Dream
About a week or so in. Leaves are praying to light gods ...
BLUE CORAL - ( Early Sexing )
Ridiculous growth .... Pencil thick branching ... All leaves are open !
No droop as leaves are getting the photons .... Lol

Whoo Hoo. This may be the first real pictures on RIU of flowering plants under a QB! Sweet. Looks like good light penetration in picture #2.
Healthy stems too. Is it stretching more than normal? These look like a winner. This is just one board in the old Mars case? Awesome.

The Blue Dream is a Humboldt Auto with a 70% sativa / 30% indica mix. Sativas do stretch a bit but she is now mostly flowering and i think she will pretty much sit pretty.
She is 42" from bottom to top. Main cola is 4 nodes in length but will add more photos once it begins to fill in. Both are in 18/6 schedule with temps between 68° and 72° running all day.
The Blue Coral is a Moxie breed cut with lemon og. Heavy indica. I plan to update grow as it begins to build. But for a 1 panel build it is killin it against that chinese bullshit.
Stay tuned.

Cool. Looks like it is killin it. What is the deal about 18/6 in flower? Are you going to slowly taper down to 12/12 by going 17/7.16/8, etc? I am curious. They look great.

Nah .... 18/6 all the way thru .... Their autos so no need.

Do you get more yield with autos with longer lights on schedule?
Ive never run autos

how many of these qb boards would you place in a 4x4 tent

Minimum 4 on a pair of HLG 240H C1050s. I've built a few custom units for a great customer of mine and they are bright and will do great in a 4x4. I'll post more pics as I only took this one too send @robincnn. This is the back side of it. The buyer liked the first 5 so much he ordered 6 more and is eventually switching all 60 of his Nanolux DEs to these.

ok so these are starting to remind me of mars panels.how do we know the cooling is going to keep these going longer than 14 to 16 months like a mars starts to burn out strings of diodes?
steve,will you be using any kind of paste between the boards/aluminum sheet/and heatsinks in this photo you just posted? whats the total output wattage using those pair of 2100ma drivers ? thats about the perfect size fixture to compete with hid

With no air movement (which should never be the case in a grow room) these run 55-60C @ the above suggested drive current which is well below the 100C maximum and most luminares that use mid-power run at around 85C. The Philips Lumileds 3030 2D we use in the razor 250 is color binned at 85C! Heat is the drivers biggest enemy. Also most Mars panels aren't even 1/2 as efficient as these. Lots of heat for the light provided. No paste is necessary as the copper layer distributes the heat evenly across the board. As can be seen in the thermal images the heat really is super even. @robincnn has tested these with thermocouples and the camera is spot on. I think you would exceed the maximum allowable current on the diodes before you would need a thermal interface material.
2 HLG 240H 2100/1050 A version will pull 600 watts turned to full bore. I like to run these at around 550 watts to give the driver a little head room. The output is something to be seen for sure. Like I said the guy that runs Nanolux and is a grower in CO bought the razor 250s and loved them. I sent him 4 QBs on a 320 H with no heatsinks on a flat aluminum plate he wanted more. I told him I could increase the power with the addition of the heatsinks. He got 4 of those and called me and ordered 6 more. He's eventually going to switch out all 60 DEs. Woot
Hell the Tj is only 2-3C higher than the case temp!
The face of the led only runs 1-2C higher than the board. Copper moves heat 2X better than pure aluminum. Now if you consider most heatsinks are alloys that move heat even less efficiently than pure aluminum you can begin to see how these do so well.
