no co2.
And one last thing, 320 watts for 4 qb 132 is already more than the maximum, I would dim them a little to be safe. The maximum hlg lists is 75 watts but the real maximum is 79.2 watts. 80 watts is already over that.
I agree its a compelling alternative although your numbers aree slightly of: at 750mA or 1.65w these xpgs will run approx 3.5/j at 25C and unless you match the diode count of almost 2300 white diodes its going to be hard to get to diablo efficiency. But you know what, with a build like this it matters very little the spread out nature of the build gives you an extra advantage in spread and photons not lost to walls compared to more compact builds. Many ways to skin this cat.To match the 660nm content of qb96 elite you would need to add like 5% 660nm deep red. For 750 watts that would be like 37.5 watts. Rapidled sells solderless red diodes that make it very easy to build supplemental strips. You could make 3 rows of 5 660nm cree xpg3 diodes and have more deep red than the qb 96 elite. Those diodes run at 4umoles/joule so they would bring the efficiency of the qb 132 to a similar efficiency that the 650R.
Maybe my numero where wrong , sorry I needed coffee and my memory did not serve my right. By close I mean 2.72umoles/joule or something like that.
The numers of the 650r includes driver so its hard to calculate, the 4umols of the xpg is top bin on nominal but rapid got the mid bin. Apparently top bin is next to impossible to source. The real deal is about getting tthe photons to cannopy which what you propose does real well.
Thanks, that is right we should also take into account that the driver runs at 95% max efficiency so that brings the efficiency down a little.
Just saved me $50! THANKS!
Did you go with the 132's?
Sweet. Post pics when you put it together. I'm interested. Congrats.
Top bin, we only stock the top bin, all our products use the G bin, dont see the point in selling any other bin
It's going to be efficient enough for me. I'm running 1600 watts, waiting until I could build the LED array. I'm actually going to build 2 arrays, instead of one big one. I think it'd be a little easier to manage.
Good thinking !!
What’s the difference between the r-spec and the Diablo board?
r spec is 3000k+660 nm and diablo is 4000k+660nm. diablo also has more diodes i believe its more efficient.
More than double the diodes.
Gotcha. Thanks. You wouldn’t happen to know what driver is used on the hlg 320 kits do you? I’m going that route but seems to be substantially cheaper piecing it all together myself ( at least so far )
Actually the Rspec's use
Meanwell HLG-320H LED Driver.
