True. I'm only scratching the surface of COB LED, it's revolutionary. Cost is the next frontier and it's already coming down.

All depends on the foot print really. If for 100 bucks you could build a cob veg lamp and cover a 2x4 foot area, then yes you'd be rich in no time.

Oh yeah, get ready cuz they're coming. I just put 315W CMH lights in my veg and I'm wondering if it's the last HID upgrade I'll make.

Its the best option out right now, those 315 kits are. Not the kits but the full hood and shit are flying off the shelves where i live.

I'm on the fence about those 315's.... not entirely impressed.
Tittysticks what's up with the LED's? Everything still running good? Notice any differences in growth? I know we'll need to wait a full cycle to know for sure but was wondering how the first few weeks are looking so far.

3x3 foot print is what I'm being told. So 2 of them is some pretty serious garden space.

I'm building a light that I'll upgrade the COBs on in the future. I'm building three, 40" x 4.84" heatsinks to run passive, each will have 5 CXA 2530 running at about 25 watts each. I'll have $400-$425 in them total. I'm using Meanwell HLG-185H-C1050B so I could drive them harder than 700ma if I need to. You could light a 2x4 area with one panel in veg I believe. Going to test that theory myself!

I'm not. 315W CMH lights kick ass with the LFSW ballast. I just replaced over 3400W of mixed HID lighting with less than 2kW of 315W CMH, and I think PAR increased.

Ok, get me a prototype. How much you looking for for an first time investment? Will 5 grand get us started? How blue can you go? Lets get this money and beat the shit out of T-5's for vegging.

They've just about completed four weeks. Stretch is over, they ended up pretty squat compared to what I'm used to, but budset is coming on hard with lots of hairs everywhere.
My fuck up with the EC will cost some yield, but it still looks like it will be a decent run.

I just did the math for my modules; they pull a kill a watt confirmed 224W from the wall, or 54W for each of 4 CXB3590 3500K CD bin 72V plus 8V for the Meanwell hlg-185-c700b driver itself. If my math is incorrect, please chime in and help a growther out!
Ok, so moving on to performance, the above combo is advertised at 56% efficient at producing PAR from 216W, cuz B model over drives by 8% if the dimming circuit is left capped:
216W x .56 = 120.96PARW/6 sq ft = 20PARW/sq ft.
I was told this equates to 824PPfD but I don't know the math on that either, would love to have someone help me walk thru the formulas to confirm all this.
So each module then delivers 824PPfD to a sixpack shaped 2' x 3'. Four of these nicely cover a 4' x 6' trellis panel. Six trellis panels make up the test rack. Not sure where it fits in, but the rack is meant to be 24" from the canopy and the modules run 80 degree lenses.

I repeat all this occasionally to provide a reference for comparison to what I've had before, what I'll do later, and what others are running.
Tonight's occasion is the COB test done on the vertical plant that the owner concluded was inadequate to replace their trusty HPS lamps.
The original design, a pic of which is still on the thread, was a box with COBS on all four sides. 800W in this shape would seem to be a good match for a thouie hung vertically. It wouldn't need lenses because it's designed to throw light in all directions. I still think this design has possibilities, and @legallyflying I suggest you try it again in this configuration. It would be a simple and low risk swap for a thousand watt HPS.
When the design was split into several component pieces, two things happened; one, it lost its ability to be compared directly to a thousand watt lamp anywhere, and two it had the original advantage of no lenses or reflectors turned into a disadvantage; there are fears of light lost because it's missing the plant entirely? Not sure if that's the case in your setup.
If the pieces were assembled into a flat array, they could once again bring their advantage of distributed light intensity fruitfully to bear. Maybe if all the cobs were aimed at a wall of buds it would also do better? Your panels are flat, just like mine... dunno, spitballing.

Here, I'll add some more dribble.
My Pax 2 started having blinking blue light faults. I bought 2 at the same time and the power button stopped working on the one I gave my friend after 3 months afterwhich he disected it and performed surgery himself few times before contacting Ploom where they told him they couldnt fix it even if HE paid for it, so he smashed it into bits with a sledge hammer
.
Now after that I started cleaning mine religiously and it has performed perfectly, until this fucking blue light started blinking and it won't function. Send it back they say, we'll replace it. I've only had it for ~9 months

I ran out of the car before he had a chance to remember my wallet which since I was being an idiot showing up there in the first place was empty and wouldn't have mattered. But I walked by there tripping my balls off laughing twice in the last month lol I call them donations to greedy fucks that are broke and always will be! Tystikk your plants are awesome I just suit my petitioning shit lol I'm flying the whole crew out to the grow room lol someone else can get the last 30000 signatures for this shit its great if your broke I guess lol I'm at the waffle house...oh shit our boss got arrested last night...maybe there's no work and I get an extra night of free super 8 fuck I don't want to stay here I forgot they won't let us stay in a hotel we might actually get girls to show up at lol ya ok its s scam lol actually its easy but I can't stay out of the bars lol I'm manic perhaps.Well that's not a very good feeling, I know, the memories are still here. As they say, if you were there you never forget war!
I hope you just gave it to them, you can always grow more alive than you can dead.

Pages 69-72 have a lot of bud porn is what he means, lol. Also put down the crack, you've had enough. Smoke some of this-here RIU rock, instead.
