thanks for info about these uPowerTek drivers :-). Do you maybe now where to find them to buy inside EU? are there any other good drivers except mean well, upowertek and maybe TRK (don't know if you can find them in EU) that you can find on the EU teritory? thanks. Sorry I don't know where you can ...

So running at 30w per square foot, these get about 0.1w per diode? would they be running at 3% of max load, and what kind of efficiency does that result in? Also, is it too early to ask about price? Seems to be pretty top shelf stuff :D Hey man! I designed these with running 50W/sqft in mind, and u...

See from outside you can't even really tell what it is

Hey guys, I'm a design engineer who has played a lot with grow builds over the years, mostly just for the fun of building them. I end up selling them for way too cheap, but the experience gained and the satisfaction of making stuff is invaluable. Check out this mini DWC PC case I built. It was initi...

Sucks to hear dude! Drobe builds are cool. Hey I built a grow-factory style wardrobe in 2011, here are a few pics.

Looking good! I also agree about the 1:1 PCB shape, given that most grow tents come in squares. The question of course is who are you contracting ;) Thanks! Yeah rectangular boards have bugged me for some time. I investigated building these with quantum boards initially, but as an engineer, the rec...

Hi everybody! Long time lurker, first time posting. I've got a little something to show you guys! I've just built my first batch of prototypes and hope to be selling these as complete luminaires very soon. Each board has 320 LM561C S6 diodes on it for that mad diode density! I performed loads of PPF...
