Well the new chilled growcraft proto1 fixture (3.2umol/j) is NOT for you then, lol. Ultra low current and a shit load of top bin diodes (8000+) to hit that #. Will be pricey with that BOM obviously.......
You're right, the price tag on the newest fixtures aren't my thing. I'll buy those a year after release if they are really so great for half the price. That said, does the chilled fixture really hit those numbers? I mean they have posted skewed numbers in the past, which didn't include driver loss, and was disproved by an independent third party sphere test. I don't really like cobs. Don't like the spread at all. I'm currently a QB96 guy, which uses the 5050 diodes so they can be cranked up hotter. They only get around 2.4 u/j but I'm ok with that.Well the new chilled growcraft proto1 fixture (3.2umol/j) is NOT for you then, lol.

Cobs are your friend in that case, some of the og never switched to boards/strips with decent grow heights. Also not using the term " penetration" cause of the Nazi tech guys roaming here
Happy fucking new year
Interesting fixture. What's with the hose, water cooled?
yes watercooled, so the idea is to use less leds, crank them hard, but maintain efficacy but running cool at higher drive with active cooling, less leds, higher penetration with 5050 leds and as you can see the new Cree K Class 5050 is still over 3umol/j at 150ma.
That's dope. What's the spectrum look like on those chips?
Did they? Didn't follow the drama but Vitally is a smart cat ..... Find it odd to leave out the drivers in a system efficacy test. Honestly, I haven't really paid much attention since gm5 left. Light labs is a reputable testing center no doubt.
Not a fan of water cooling but that's a badass light
They talk about it during the first 15 minutes of this GML show..
yes I thought the numbers without the driver losses kinda wierd
this one is a special 4k 95CRI, but the 5050 are available in all the same spectrums as single die 3030, 2835 etc
Hard to watch with some kids screaming into the mic. Not a fan of these shows and gml is a direct competitor with his Canada distribution== No matter what he says.
I agree, im working in a new lamp that has duris s8 ( 3000k and 5000 k cri 70 ) and oslon square 660 nm (bin 8 ) and oslon 730 nm .
That's cool, but I'm not sure I want 730nm on my main lights. I prefer to run far red separately, so that I can control how much far red the plants get and at what time of day. I've had some strains get a bit too stretchy when running 730nm all day during transition.
Me too, but these are cri 70 white lights and only one far red diode , just i litle bump like in cri 90 white lights .
So your reason for testing a single bar vs the entire fixture, is that you think your fixture will block light bounce? Erm, I'm pretty sure that's what happens in any tent grow situation. Additionally you are using math based on theoretical driver efficiency based on spec sheets at 220AC, but in reality most growers will be running 120V AC, so there's another 5% drop in efficiency right there. The reality is that you are posting a theoretical efficiency number for you fixture, based on math, it's not a real test of the fixture. Fact.The Growcraft Ultra Proto-1 has been, and is still, undergoing independent lab and grower tests to back up our initial claims for this new light. As for our "skewed numbers" on the Growcraft we responded to those allegations with a transparent explanation as to why we decided to test our bars the way we did. If you need me to further elaborate on our findings feel free to shoot us a direct message! -Dallas
Our μmole/J Testing Process
Recently, one of our Growcraft X6 600W was acquired by a competitor and sent to a lab for testing. Their results measured a lower efficacy than what we list on our website; we hope this is because of the discrepancy of test parameters between our tests vs theirs and not due to any intentional...chilledgrowlights.com
