FLIP CHIP OPTO LUNA 300!!!

I'm confused. The Luna 300 had two listings in the spec.

320 watts and 600 and something. Can it be driven at 600?

What did you figure for efficiency at 320 watts?
Advantage of running one 320 vs let's say 4 75 watt chips?
Coverage?
Thats just it; four point sources are always going to be better than one big one in terms of even light distribution.

Unless I'm missing something significant?

That's a matter of scale though. 4 75's would be better in a 3x3 or close to it. Then four 320's would be better in let's say a warehouse? Or would it?
I'm putting part of this to the test, by building a large array of COBs running at fifty watts apiece. My theory is that more sources of light makes for better light distribution across the canopy and therefore better yields and more consistent quality.

I am thinking on a bigger scale. Just because my first lights can run at 320 watts doesn't mean that they have to be ran that high. I am going to run 2 320 watts 18" apart in an agrotech reflector, just to see. The plants I have under a 500 watt stadium light with the same hood has much better bottom growth than under my Vero 29s @ 25 watts or 50 watts. Since I am paying the same for the Luna 300 and the CLU550, they may eventually be ran around 150 watts. I don't know yet. The one I am vegging with is turned down to 230 watts at the moment. Why not 320 watt units in a green house hooked to a light sensor to dim when needed.

Hello There! This is Alex from Flip Chip Opto.

Let me know if there is any technical questions I may be able to answer!

Hi! We like to under drive COB chips to boost efficiency, so likely the burning question on everyone's mind is what the current droop curve looks like for this chip, especially below 50% of rated output?

Also, I'm sure we'd love to hear your recommendations for heat sink typesand performance?

Welcome Alex !

I've some questions ...

1) When we should expect the Duet series to hit the " shelves " ?

2) Why so much " blue" output power ,comparing to the " red " one ( Duet 2400 ) ?

3) Have you considered the homocentric circles design( like a " target " ) instead of the " BMW logo -style" or " Yin-Yang" , for better spatial & polar spectral distribution over leaf canopy ( Duet 2400 ) ?

4) 56 % radiant efficiency for the "blue " part at 6A .. ( Duet 2400 )
Seems rather fine ...
What about the "red " part ? Can we have a radiant efficiency figure there ,please ?
(You will save us ,from some reverse engineering trouble ...)

5) Should we expect some more of Duet models (i.e. less wattage or other spectral combinations , like i.e. 5000K CW -instead of 455 nm - plus Broadband Conversion 660 nm ==> for less blue and more "green" & "amber " content ) ?

Cheers from Hellas and Thank you in advance ..
:peace:


P.S.

Hey Alex, I hope Danny didn't take that critique the wrong way. Just we have been trying to get away from the blurple (red blue) panels and 1100 watts of blue and red from a point source would need to be way to high. Me and my plants are loving the Luna 300 though. These will be great on a HLG 240. I have this one on a HLG 320 just to see if I can hit over 1.2GPW, but vegging right now at under 240 in a 4'x2' tray. Some type of holder would be nice, I don't like the look of the exposed wires. This is the second time I have cut this hood down for a led light.
