I found myself slow clapping :clap: to the video when you were talking about mainlining in a 3'x3' under those diy AB's. I might have to retire my "old" Z4's once the AB's arrive. Watch yourself with the diy it can be more fun than gardening and become addictive. j/k I can not believe you are...

Here were a couple of garden monitor projects is was watching but one seems to be stalled/abandoned Open source versions of of that parrot thing. http://gardenbot.org/ http://www.harvestgeek.com/ and an alternative one...

I soak a whole sheet of sandpaper on the sink and stick it to my bathroom mirror. I then dip the heat sink in the water from the tap and slide it on the paper, the water and aluminum dust just drip down the mirror. I Repeat this with finer sandpaper until I'm happy. the water holds the paper to...

I would be happy to see some 2.7k z4/z2's or some more 3k z4's available.

^^^^^^^^ Do not grind them https://www.rollitup.org/t/cob-holders-the-basics.805034/

I carefully drilled and taped the aluminum plate on the back of the fasttech drivers, attached them to a length of angle aluminum with screws and mounted them vertically in a old PC power supply case. I even reused the psu's switch, emi filter and fan.

The LPC-35-1400 will not work with the cxa30**'s as it only has an output of 9-24v, the cobs require a Vf of around 36 typically and can run up to 42v according the the spec sheet from cree. The LPC-60-1400 will work

So for a 2x4' space I would only need 2-3 watts? for diy would these work run off this driver?

www.rollitup.org/t/flowering-with-cree-bulbs.656542/ captainmorgan killed it using household Cree bulbs, I would read that,

If your comfortable with DIY I would do that. I bought some rw-150s before I started the diy also, now I'm hooked on the diy and want to keep building, also I am a sign builder and work with LED. I love these little glowing diodes. If you added 4x30 watt cxa3070 would be enough; but you could...

Come up with another $45 and get a rw-75 while they are on sale, good for veg and bloom.

Sev, Those look great so I know your going to be happy. As for the coverage of the rw75, on their website it states the Maximum coverage of that light is 24x24" (4 ft² 19.38w/sf), the Optimal is 20x20" (2.78 ft² 27.88/sf) and Minimum being 18x18" (2.25 ft² 34.44w/sf). The specs for the rw150...

^^^^^ 10'x10' is huge for a tent, I bet you can fit a jungle in there. Another DSLR trick is to get a reverse macro ring so you can get real close for cheap ($30) Here is a quick pic of some Bubba from my local dispensary; with the reverse ring. lighting is not optimal as I just took the pic...

Magic lantern is an awesome firmware hack. it also lets me record 1080p 30fps on my 500D which only does 20fps stock. There is another must have thing for canons, DSLR CONTROLLER for android That's a great price, I paid 1.5 times that for my GGT24 after shipping and import fees when they first...

I have never used this and only stumbled across it but, there is a product called Wire Glue. Google it. It is a electrically conductive glue that could be used instead of soldering. A lead wire could be permanently glued on to the led, the rest is "easy". So to say.

3300 manual points!! your awesome man. Today Salmonetin posted a video about some software that could do that for you possibly.

I don't know much about pre-made led panels. There is a small (9x12x2.75") a51 rw75, but I think it is still to big for you as it needs to vent out the sides. There is also the Onyx panels which are gaining popularity around here and though it might fit in your space (6x13x2") it could be...

GG do you got a link to the source of these AB's?

With the drivers and these type of leds you only deal with low voltage (around 37 volts) and could be done with crimp connectors and solder-less led holders. if interested in learning more about this, check it this and this I had trouble with soldering at first, drove me crazy then I found...

At that size I would suggest going DIY. 2 Cree CXA's run at 50watt each would run cooler and brighter than any UFO or cfl with more value for your $$$. bbspills has done very well with 2 2700k CXA3050's, though harder to find the cxa3070 3000k seams to be the favourite around here, just not...
