I'll do just that. I can take some area/average measurements under a few diff lights and post. I think there may be some bias as different watts, but more information can't be a bad thing. Thanks again!

No doubt, I'm behind the curve :D waaay behind

Not a bad idea, I can see that! I suppose I had envisioned a pre-made box or choice of such, and if it was wired with some switches etc.. a bonus! They sell these LED panels on ebay/amazon for peanuts, there must be a source?

Well said.. dig it! I'm sure (at least in my case) we are the bottleneck in the equation. As it looks like commercial AG outfits are coming to market soon in some states, it'll be scary to see just how good this stuff gets.. it may get cheap enough where this is just a hobby.. I mean, if they...

As it seems many of us have used recycled metal boxes and other *stuff* for these DIY/COB lights, and I just read a moment ago about using a no-longer-wanted LED panel to fit with COBs etc.. Leads me to wonder, are there places that you can order pre-made boxes with switches/cords etc? I can...

When I read this, I'm thinking.. really? Then I think... Wowser, to think that's possible with these or any lights.. that'd be awesome!

Thanks for the replies! I think reading the posts here is kind of a... "you don't what you don't know until you know"?? Or something like that. @SupraSPL I've read about IR and lack of IR via COB's. Is the lack of this a bad thing? I seem to perceive reading through here that the pros of the...

I'm hoping so too! The information and responses here are awesome! Thanks to all!

FranJan, thanks for the replies! That's some great insight as to what may be happening. As far as the IR portion, is that something that is considered *missing* from COB's? I haven't seen much mentioned about that. Maybe small t8's or something that are in the IR spectrum? There is a fan not...

Not getting in the commercial part (snipped) but I hope to be as enthusiastic as you! The HID's are effective, but a pain in the butt to deal with. I'm hoping to do the same thing, toss the HID as far as I can, as soon as I can! Cheers!

Only by accident :D I'd take the glass off to measure temps, but it's a hassle and I don't have much headroom... might burn em up. It would definitely seem (and the camera proves it) that cobs are cooler than HID.. I wonder if there's any information about different transpiration rates. I think...

Well, I'm using a camera from work to see how hot my DIY COB is compared to the HPS. Here's the drill. The HPS is air cooled, and set at 450 watts, the cob is a DIY 4 x CXB3070, about 220 watts.. I noticed that the canopy is a little cooler under the COB, and almost looks like more...

Couple pics, forgot to take pic of front. Great info here to build a light here. Used 4CXB3070s was AB or AD bin, don't remember.. have one more to put together. Glass lenses, runs cool/quiet.

Oddly enough, I found tapping the heatsink and every part of doing this was a breeze, the chips popping out of the ideal holders was one of the most frustrating parts IMO. I honestly thought of using adhesive TIM or kapton and just soldering next time. Maybe it just takes practice, but I thought...

Thanks! I went ahead and grabbed some alpine 11 plus coolers.. should be good. I'm planning on using 2 heat sinks, maybe 8 or 10" x 24" or so, with 4 CXB3070 driven by a 1400 MW driver. Having had a CPU cooler fan freeze up, I kind of like the idea of larger/single sink to dissipate heat with...

Anybody used the Arctic Plus 11 with the Ideal holders for the COB CXB3070 ? Thanks!

Hello! This is a newb question I'm sure (and my first post!) I'll be putting together a fixture with: CXB3070's and Ideal holder 50-2234C I see a lot of recs for the Arctic CPU coolers... the 11 plus to be specific. My question is... will the Ideal holder 50-2234C fit on this? Also, is a...

Hello all! New here had read many of the posts and couldn't think of a reason to not join in! I'm a MMJ patient, as well as a curious observer, always looking how I can improve my health and quality of life, there's so much here. I'll try to help where I can as well.
