True. Not sure what I was thinking.Thanks. But 100% efficient lamp doesn't mean infinite g/W. If the limit for 50% efficient one were 2g/W (or whatever), then 100% would achieved 4g/W.

oops fixed , yeah infinite gpw lolI can see that now But the post you quoted was actually for @draz
I don't recall blowing hard. I recall making logical statements which you happen to disgree with. Does Rollitup forum condone petty namecalling? Cuz if so then I'm actually very good at insult contests. You'd be surprised at the creative names I can come up with. Now, simple fact is; full sunlight only produces a certain yield and I haven't seen any cob lights yet that put out 2000 PPFD like the sun. SK comes close, if only under the middle of the light, but it is 18" away so that's still pretty impressive. The LEDs they use may not be the most efficient but they have lots of them in a small area so they do the job. I think you just have a problem with the SK company because you're an SK hater. Why? I don't know. Maybe the owner married your sister and isn't treating her right, who knows.hi alesh, suggest you give up on Cajun, a lost cause, nothing more than a blowhard that recites but doesn't understand.
Any COB light can put out 2000 PPFD if you move close enough So much about logical statements. Don't make me find a few moreI don't recall blowing hard.

Suggest you quit before you are sliced and diced. You have not been logical, youve not been cogent and its doubtful you will succeed at being nasty.I don't recall blowing hard.

I'd think if they were they would brag about it.Sounds like that light is using XM-l2's. Are we positive that the SK uses XB-D's and not XM-l2's? That would change things quite a bit if they did...
Actually I found a high bay that uses xml 2s u2 bin supposedly. The price is 100 bucks more but seems to be worth it. Still the lm/w doesn't add up.Sounds like that light is using XM-l2's. Are we positive that the SK uses XB-D's and not XM-l2's? That would change things quite a bit if they did...
Did some more playing around with the Cree (PCT) and found some interesting results. So the XM-L2 in the higher/highest bins produces over 145 Lumens/ Watt @ 700 ma 50 degrees C. SK claims to use 200 diodes on the SK400. If they did use XM-L2's then I could see 200 of those within close proximity of each other producing some serious light density.Actually I found a high bay that uses xml 2s u2 bin supposedly.

I completely agree. Those new chips are super badass. Apparently those can produce upwards of 160 Lumens/ Watt (higher bins) at just 200ma 50 degrees C. Cram a bunch of those together and...call me when they start putting cree XHP in deez bitches.
Yeah but they don't. XM-L2s are about 5x more expensive than XB-Ds. Can't imagine how ridiculous the pricing would be.Did some more playing around with the Cree (PCT) and found some interesting results.

Or use a COB and make it easier, cheaper and more efficient.I completely agree. Those new chips are super badass. Apparently those can produce upwards of 160 Lumens/ Watt (higher bins) at just 200ma 50 degrees C. Cram a bunch of those together and...
How were you able to determine that SK uses XB-D's? And please don't say because that's what comes on the Alibaba high bay.Yeah but they don't. XM-L2s are about 5x more expensive than XB-Ds. Can't imagine how ridiculous the pricing would be.

that actually looks like a pretty decent light, price wise beats the pants off of my illumitex.. distribution seems to be its weak point, and they may be over estimating that 525 watts can replace a 1K hps. the website didn't really say what chips they are using.http://getnextlight.com/nextlight/index.php?route=product/product&path=60&product_id=42 $1300 for 525w of top group/bin? WW xml2 (ul $$$ rated too) , not bad really and would crush SK's fixture(s) in every aspect...........
If you are are ordering in the 1000's the XM-L2's can cost between $2-$3 per chip... Maybe less if your company is endorsed by Cree...Yeah but they don't. XM-L2s are about 5x more expensive than XB-Ds. Can't imagine how ridiculous the pricing would be.
Would or does? So much speculationhttp://getnextlight.com/nextlight/index.php?route=product/product&path=60&product_id=42 $1300 for 525w of top group/bin? WW xml2 (ul $$$ rated too) , not bad really and would crush SK's fixture(s) in every aspect...........
Nick is a smart cat, but looking at the par charts it's NOT a thouie swap, no way will it cover a 4x4 for flowering MJ. He dabbled with xhp's 50/70s for the V2, didn't like them for some reason, probably too costly is my guess. Still a decent light for the money for pre-built/commercial ops(ul).that actually looks like a pretty decent light, price wise beats the pants off of my illumitex.. distribution seems to be its weak point, and they may be over estimating that 525 watts can replace a 1K hps. the website didn't really say what chips they are using.
#s don't lie, marketing doesWould or does? So much speculation
