Pinstripe's 2nd try: PC case + 22W LED

There is no any comercial unit using LEDs with that efficiency right now. Im working on that, but its not avalaible yet.

Building it yourself dont require any special skills, just the will and some free hours. Not difficult at all.

Is this enough for a 8"x20"x26" cabinet? Can someone recommend a driver for these as well? Thanks!

Yep, Digikey is usually the cheaper distributor for them, both in Europe an the US/Canada.

But there is a better option, me :dance013: I buy reels of those LEDs ta the industrial level, so I can get them very cheap (not as cheap as digikey, of course) and resell them charging a minimun profit margin, so the end price is way cheaper. For example, for the coolwhites (LUW-W5AM), I have the bin LX (112-130lm#350mA) and Im selling it for 3.5€ from the first unit, and Ive been selling the KZ bin for 2.3€, about 1/3 of Digikey, and less than half still if you get 100 there

Same for blues, although I carry deep blue (LD, about 450nm peak) instead of blue (LB,470nm). I carry the 1U bin (450-500mW#350mA) that is a top bin currently, way beter than the range GY-HY on LB, for 3€.

For the reds, I carry the normal GD instead of the Plus, due it cost about half with similar range of bins. For example, I have the JX for 1.3€. The only relevant difference in red between both models is a slightly lower thermal resistance for the Plus and the beam angle (120º for GD, 170º for Plus).

I want to open a ebay shop soon so people dont have to contact me by PM and so. Im going to receive a batch of high efficiency 660nm high power LEDs next week and I think many people is going to be interested, at its not avalaible anywhere, so I need a way to do things faster and easier (until now, I prefered direct contact trying to ensure people know what they are getting and how to use and mount it, looking for feedback from them: its my way of testing things before releasing a comercial lamp)

Im on other forums with same nick, that allows to send/receive PM since you register, as The Garden's Cure or Greenpinelane.

Too on my local forum, cannabiscafe.net, a spanish forum (but I believe you can select english as lenguaje, at least for menus and so, obviously for threads you will need a translator; but I can read a message in english aswell there as here). Im knnabinoide there.

knna hasn't been heard from in quite some time. i expect he's moved on to other things and certainly wish him the best.

great history in this thread, this was the grow that inspired me to build my own light/PC box.
