Yes one of diyleduk'sleave it in the box, mate. you have too many lights
nice rake.
it'll be interesting to see what that scope 240 puts out...its one of diyleduk' isnt it? what size space you using it in?

Didnt even realise he had these, just picked up a new v2 265w QB kit of him this week in 4000k...
The scope looks pretty tasty.

Knock offs still rocking
3 x RQS Royal Gorrilla cuttings
2 x Paradise Seeds Sensi Star original cuttings
1 x Somango from seed
Somango - back left, nearly touching the QB.
Gorrillas back centre
Sensi Star front and left
Gorrillas back left, back centre, front left
Sensi Star front
Sensi Star original what a Star! - notice the burple light behind it that's trained on the Somango
Somango - getting a head massage of photons from the QB whilst enjoying A shower of full spectrum light on the side
A bit like this......
Fecken Chinese knock offs......, imagine what you could do with the real ones

Love Somango, excellent smoke. As far as knock offs, im getting more and more convinced that theres very little difference, i think most of the meijiu is S6, just that you get standard voltage bin jnstead of the super-low bin of hlg. Same amount of light but a little higher voltage. Doesnt really bother me if i spend a few % more power for the same light. And if you get 3 times the diodes for the same price as 1 qb you make those measly watts back running the diodes at a third of what youd run the qbs at. On top of that you run with a lower junction temp. I cant really exagerate how much i like the Fotop boards. The ones i got recently is up and running at my growpartners place. He was die hard HPS for years, and he is blown away with what we put together for him. Unluckily the grow will shut down after this cycle. But a new location is in the pipeline. This time it will be led based and were gonna pimp it as far as we can. Next step will be spectrum/reds/far reds/infrared and hopefully automation. But probably not until next year. Happy growing and thx for servicing the community with trying new gear

This is my build
6 x QB 288 LM301B diode
3 x big heatsink
2x HLG-320H-C2100B
2x 3/4 W x 9/16 H x 96 in. L 1/16 thick aluminum C-channel
2x 3/4 in. x 36 in L 1/8 in. Thick angle aluminum
2x 1 in. x 36 in. L 1/8 Thick flat aluminum
6 ft. Power cord cut off an old surge protector
Lots of 3/16 aluminum rivets
3-port Wago connectors
I wanted the best quality light possible, and I have heard so much about these QBs, my curiosity got the best of me. I was initially going to go with the Samsung Q-series strips from Digikey, but then I found this thread and went digging around on Alibaba. Found a seller with 288 QB w/ highest quality LM301B diodes available (or so they claim). Told me $35 each for the boards and $20 each for heatsinks. Was around $370 total for 6 boards, 3 heatsinks, and $100 shipping.
Believe it or not the boards got here quicker than the wire and wago connectors I ordered from Amazon did. I initially bought the C-channel as I was going to mount the heatsinks on top, but they fit inside the c- channel perfectly so I went that route instead as I think it makes the light more sturdy. The angle aluminum was used as rails and the flat aluminum used as support for the drivers. I tried to space the lights as well as possible for the 5 x 5, then just drilled and riveted everything together. I just put it up this Saturday and I am so excited about the quality of bud these will produce.

Their thermal trigger is pretty cool

For the boards or for extraction? I doubt they have much power to press air thru ducts or filters. Although recently read that a under powered fan is good idea for cargon filters. The air having more time in contact with the filter supposedly makes it remove smell more effectively. But with so low cfm im not sure it would extract enough to keep anything but a small cab cool. What would be cool aswell isnif the thermal switch could be adapted to other temps. Only the lowest 84 setting seems usable for growing as i dont need a 92f setting, would be a fair bit to warm. Also seems to be stop and go, not lowering fan speed which means no airflow if under the temp setting.
Interesting if someone tried for a low tech temp control solution, but theres plenty of reason to believe its not going to work all that well. But who knows til trying

I have used these to good effect in flower rooms
A "one off cost option" that'll last years.

The 4x288 = 1152 diodes vs 2x800 boards = 1600
Which means for the same power one will be much more efficient.. id compare 6x288 boards to 2x800 and I would bet both options would be similar.. it depends on your set up which driver you want to use i run 4x304 boards at 520w with heatsink but I know you can run the 800 boards without heatsink at 200w each.. if you can get some cooling on your 800 boards id probably go for 2 of those at 300w each with proper cooling and should do great in a 4x4.. at 520w on my 4 boards its doing great but I feel id benefit from a few more watts for my 4x4 space..

My goto solution for a 4x4 would be 3x Fotop but no heatsinks on a hlg480h-48. No need to for heatsinks up to 200w, especially if you got decent airflow. Without the heatsinks shipping should be cheaper. I think i paid 75 each + about 120 shipping to spain= about 350
You can also get 9-12 304 boards and run them super soft, about 30 w each. I think we paid about 20 per 304 board, lm561c.
When comparing lm561c and 301b fotop we came to the conclusion that the price increase was simply not worth it: 3 boards with lm561c was about the same price as 2 of lm301b and the therewasnt all that much difference in light, board per board.
Also 304 boards are smaller so they allow you to really dial in your spread, but more work connecting and dirver options are a bit trickier.

Nice and not very pricey!
The contoller, does "dim" fan or does it turn it on and off?
