Quantum boards only need to be wired up and hung.

I asked Mike at Atreum about selling bare modules. He said they don’t plan on it since their goal is plug and play. I’m left to wonder why such key data and numbers haven’t been provided either. I hope they are currently being tested by 3rd party. Same situation with their 144.2 board. I...

Lol I suggested you listen to the previous replies. Re read it, maybe you’ll catch that.

I suspect your sourcing this board from China? Buying such a board from China is a roll of the dice. And I’d listen to the other replies you got. Such a board definitely isn’t very practical even if it came as advertised. Your asking airwalk if he’s ever heard of parallel with a snarky tone...

Check the hole size with drill bits.

They are going to be used for testing different micro greens and vegetables so I’ll be making a bunch of different color combos on 1ft fin heatsinks. I basically got every different spectrum diode on Steve’s website from various brands. Lime, mint, true green, deep green, royal blue, cool...

What’s your opinion on Luxeon Sunplus20 deep red, Luxeon es deep red, vs the osram and cree you mention in the post below. I purchased a bunch of these from Steve’sLEDs. They seem crazy cheap to me. Also threw in a bunch of SemiLED deep reds last link...

Damn thanks for all that! I have stacks of Eb2’s laying around. That’s all I use so I am well versed in their capabilities. They have proven very well for me. I also have a few vests strips just cause I wanted to have some on hand threw them into my cart a long time ago. The new edge strips...

Yep. The new strips are all the way at the bottom past all the COBs. Called Vesta Edge. Not technically stated as Gen2 but quite different. https://www.bridgelux.com/products/vesta-series

The new ones are only 132lm/w! 90cri 27k & 5k Their website gives some preliminary specs.

I believe @Randomblame knows. He is a wizard.

Old thread but I love your insight. There may be more discussion elsewhere so my apologies if this is duplicate. Do you still feel the same as you did when you wrote this middle of last year? Very interesting how you figured out the same diode is likely used between Eb Gen1, Gen2, and Vesta...

Thinking strictly based on CFM values I often wonder why DC isn't utilized. DC fans will most definitly not have the pressure required for certain grows. But for simple tent extraction without any plumbing it seems very do-able. I grow vegetables and fruit and in my cucumber tent I have an...

I run several of the 144.2 boards. 60w is just the recommended wattage to run them at without heatsink. It’s merely a suggestion. They can be ran much harder or much softer. I run mine at 35-40w for efficiency because I have so many of them.

That’s awesome! Man, I dream of a discount like that some day.

I Hope that’s a good thing! Iv seen that name mentioned quite a few times.

Has this cheap thermocouple proven well for you? Pretty accurate? Can you use different/better thermocouples with the meter? Sorry to dig up old thread.

What up ROC pile! Perfect driver selection, perfect match. Same parts Iv used for multiple builds.

You going to grow vegetables under them at all? Your handle had me curious. Which 3w LEDs are you planning? I am in the process of adding a bunch of Sunplus20 LEDs to one of my Eb2 builds. And your pic is not dimensionally accurate. 12 Eb2 strips is only 30cm

Then go do it.
