They probably just wanted to compete with the growmau5 pucks imo it was a smart move.

Oh, I have no doubt it was a smart move. And even though it doesn't appeal to me, I'm always happy to see more products and options hitting the market.

Yeah it's a great budget light 2 of these with active cooling could do 600w for less than $400 thats a steal

But will the price be reasonable? And can they be ran without a heatsink at a high enough wattage to be a better alternative? I think that's the next big thing in DIY LED strip builds. Having a board/strip you can run 100-150w through with no heatsink. Just need a thicker PCB to begin with or a heatsink that comes with it that doesn't cost an arm and a leg.

completely agree, we see strips at higher power the absolute best solution, this is what we see as the first in a series of High/mid power strip products, once our boards arrive we have several heatsink solutions we will be testing to see how hard we can run these

these will be in the range of USD65.00

Its in our pipeline

96 white 5050 leds in 2 channels, 3rd channel 660/730/400 etc, 560mm Solskin strip
cool thing will be boards will be available in 12v,18v,24v and 48 volt
up to 40000 lumens per board at 200+ watts, kinda out there
Cheers

Are channels individually switched? Or are 1and 2 combined and 3rd is seperate?

Is this still the QB96 thread? Just checking...

I see these boards as a way to sacrifice a little efficiency to hang high, run HARD and gain penetration. Should be a no-brainer for tree style grows. If I didn't scrog I wouldn't hesitate to try these.

No, someone with a deep seated hatred of the QB96 Elite has warped it into the promotion of something else

They can always be under driven, it's just a cost/performance ratio to consider.

3 of them at 90w each in a 2x4, could be hung at around 12 inches. Comes out under $400.

4 of them at 70w each in a 2x4, also at 12 inches, comes out under $500.

Those prices may/may not be comparable to a different build, but I suspect the electrical efficiency and temps would be quite good at 70 watts each. I typically underdrive any build I do anyway so that's how I would think about it... and why I asked about lower wattage options.

It's something I figured would hit the market eventually if cob makers didn't start mixing 660nm in with the whites (w market leading efficiency). If I could get something like the QB96 that can hit +200 LPW at 30 watts and not cost me an arm and a leg it would be a serious contender for any new lamps I build.

They could also make good corner spot lights for strip/board builds in large tents.

My question would be what kind of spread you'd get at 12 inches. You think it would be enough to cover the 2 foot width of the space?

Seems like ChilLED's 100w, mixed-white/red PCBs designed for 140mm heatsinks might already meet your requirements?

Spread would be pretty good. I haven't done the testing to quantify how much better a low lamp is at reducing reflection, but back when I was building 4 cob bars at 75w each I was getting 80% readings at the edge in a 2x4 reflective tent at that height. Compared to HID par maps in large tents it's a big improvement.

Wasn't aware of the chilLED pucks. They do look really nice, but I couldn't justify turning them down to 30 watts at $60 a pop... but I might consider running them at 50w each depending on performance.

Vero29 + sink for 30w output will run around $40-45 and provide 200 LPW so that's the competition. I'm still using radial sinks I bought for $13 each in 2011. They ran warm with 30w Vero 18g5 but work very well at same wattage Vero 29g7. In bulk they could probably be bought for $5 each... unfortunately they can't be found in small quantity on E-bay any more. They can still be found in bulk on Alibaba. Only problem with them is the mounting surface isn't large enough for a big PCB.

Which is another issue in my case. I can upgrade these lamps I have basically for the rest of my life. New cobs and drivers and I'm done. Not a big picture kind of thing and I might be tempted to make changes eventually, but all these new products and different form factors, will be interesting to see how things settle out over the next 5-10 years. Will there still be a variety of form factors, or will one product type end up dominating the market?

Personally, I'm really looking forward to seeing more grows under red-supplemented fixtures. Seems to be picking up steam all over the place these days, but I still haven't seen much to convince me it's the cat's ass some make it out to be.

Any chance you've already run the numbers on the ChilLED puck to determine efficiency at 50w? Curious how it shakes out.

True. Someone in the far red thread mentioned the Emerson effect being effective at lower light levels, so whether it's even worth doing I don't know. I think as a general rule anything in the 580-680nm range is good stuff, so you can't really go wrong... unless it affects the umol/j potential, which is a real thing.

The QB96s 2.35 umol/j at 170 watts is looking pretty good.

I'm curious too but not motivated. Seems like it would take knowing what types of chips and the architecture one of these pucks uses, then using two or more datasheets to collect the relevant data to do the math. I'm LED lazy these days.

V1 & V2 just use LM561 and 301B respectively. The reds are 660nm Nichia.
