    First LED Build

    I decided in order to save space, I'd do a 3'x1' shelf and do 2 rows of plants. I bought a wire shelf and got a good chunk of work done today: I hung the LED assemblies using some nice steel wire. This should make it fairly easy to adjust the height as required by twisting the wire more as I...

    So your power supply is set to do 12 amps at 12 Volts? What do the specs on the lights say for power requirement?

    Well, my heatsinks arrived today and I didn't waste any time. The installation of the COBs to the sinks was actually more difficult than expected. I bought the heatsinks used off of eBay and they came with a number of holes already drilled in them from their past purpose. This made lining...

    Good choice on parts and I am using similar but Bridgelux versions in higher output and only two of them.  You are going to find they are too bright for being very close to the plants.  Finding or making a good enough heat sink will be difficult and VERY important.  I CNC'd mine and right behind...

    These parts are very expensive here in Canada (each of those COBs are a little over $100 and the driver would be $110 as well) so I did some research on another forum and found a supplier from China on Alibaba called KingBrite. I saw that many users had purchased from them, and the contact...

    One question I have - where do you get the PPFD figures and efficiency figures from above? I could not discern it from the COB data sheet.

    sweet set up!   absolutely awesome choice in components   i would like to make some recommendations (ive built a few of these so if u run into trouble just ask me)   so i assume you have the 36v version not the 72v?   in a 2x2 that much led will be brighter than the sun at the equator on a mid...

    Thanks to everyone for the warm welcome. I am VERY new to gardening and just grew my first peppers on my balcony this past summer (jalapeños and habaneros). I really enjoyed the whole process and decided to find a way to continue through the winter. I've been reading through this forum and...

    Hello all, first post here. I received my cobs and driver today that I'll be using to try and grow peppers over the cold Canadian winter - Huzzah!. I'll post an update once the rest of my parts come in and I start building in a couple weeks.   Gear consists of 4x Cree CXB3590 CD bin 3500K COBS...
