Most Efficient LED Light

This is a phenomenon I can't really explain. I've seen first hand the measurements in a tent of the Maximizer and a Gavita side by side. The Gavita should look better but it doesn't. I'm not implying anything with this just sharing what I've seen.
That is pretty interesting, though. Optical observation of light-wise, I experienced this between a BlackStar 500 and a ViparSpectra 450. The ViparSpectra light looked weaker, but all things considered, it grew better. I think the visual difference came from BlackStar using 3w diodes and ViparSpectra using 5w diodes.

A bare 1000 watt Phillips on its best day puts out about 2050-2100...... That said BARE is the key here. Reflector loss is as real as Trump being president elect. I don't have to like it but it's true lol. Reflector loss is 20%++++
Right. But his stats say a 1200w DE's putting out ~500-600 PPFD /m^2.

Well, PPFD is space dependent so the numbers by themselves don't mean anything.

The Florida Sun is apparently 89% efficient. Doesn't make any sense.

That 89% is the efficiency the passport gives to the spectrum..... Our highest reading this far is the Maximizer with 3000k 90cri citizen. Just over 60%. 3000k 80 cri falls to the low 50s. We will be doing lots of tests. Those % numbers have what significance?

Testing is done using super high tech new equipment by an unbiased party.
Well that clears things up.

Sure they do, both lights use the same space to determine the #'s Rahz.
I said on their own. Knowing the space and methodology would allow comparisons with other sources. PPFD figures on their own don't allow that. Even if the figures are correct it doesn't prove your 30% more claim over a 1200w DE. I don't know why you needed this new test. Why didn't you provide the information you used to make the 30% claim in the first place?

It sounds like you're looking for any reason to not believe.
Just looking for some clarity. If Victor released the part #s and driver currents it would clear everything up... and would take him about 5 minutes to do it. I won't speculate on why that hasn't happened.

But for instance,

3 T4-V725s will provide 2175 PPF. Those figures are based on spectral analysis for LER/QER and Bridgelux data for 18 Vero29C 3000K 80CRI at .7 amps. Total output watts, 816.

If DE is 1.7 umol/j then a 1200w unit would provide 2040 PPF. Having that data allows me to make the claim that the output for the lamps is 2.68 umol/j, 7% more light than a DE using over 400w more, and people can do the math to verify this themselves if they like without having to rely on claims by the retailer or a 3rd party.

Yep lighting passport which doesn't do multiple measurement average. So that figure is a center reading under the lamp........

I'm not buying it. Note we own the same device they are using in this test. The 1000 watt DE has a PPFD higher than 500-600 sorry. In this instance the PPFD reading is an instantaneous reading at a point. So that being said this doesn't prove anything.

Allot of speculation going on. Not good. That's how false info gets out.
You guys already know, it's 48% efficient & all top-bin using MeanWell drivers. That should do it, no? This test was done using the latest IBM statistical software run by unbiased professionals.

It's a DE killer & that's my point.
The center par #'s are what I originally used to determine 30%.
You guys are all welcome to see this all done by my hand live on the Par-mapping thread I'm doing next week on all the Amares I own.

I'm sure at 900 watts it's putting out a lot of light, but to suggest it's putting out 655 PAR watts (42% of 1200w) can't be shown with a spot measurement.

3590s run between 30 some and 60 some efficiency depending on the driver current. We don't know it's 48% efficient, that's why I was asking for drive current, for the cobs and diodes. If the seller doesn't want to provide that information that's fine, but I don't understand why they wouldn't.

What height was the measurements taken and was it in a tent or non reflective dark area?

PPFD is not a single spot measurement as I'm sure you're aware.
I said 30% was my rough estimate against the 1200 DE.
42% is against the 1000 & is not an estimate, it's a fact.
Man, you guys are trying so hard to call this bunk but it's simply not.
Didn't I just give you the info.?
Does it not say 48% on the graph? Haven't I said it was 100x on threads as well as posted the parts repeatedly?
You guys can't use cob equations on everything w/o ever taking design into account.
I'm done here for now. Got a room to build. Can't be going back in forth w/ non-believers in the truth all day.
You both make good lights I'm sure, got nothing bad to say about either of you.
At one point though, you're just gonna have to accept the facts. Amare is killing it
w/ results & #'s.

If a 1200w DE is 42% efficient and outputs 504 PAR watts, then a 900w lamp with 30% more output (655 PAR watts) would be 73% efficient. If the output watts is less than 900 then it would be +75% efficient, which I doubted and still do. That's why I asked you to prove your claim... not calling anything bunk, just questioning your figures.
