both of the lights in the OP are customizable. the CLW has veg vs bloom (and the veg stacks tough), and the kind has red, blue, and 'white' bands ('white' = everything else = orange+purple+ ir+uv i believe)
maybe ill shoot the kind fixture on pure red pure blue and pure white with the other bands turned off
Thanks! I'm using the Cree PAR38 (flood) right now.
If you ever have a GE Bright Stik available, I'd like to know what that spectrum looks like (cool and warm, if that's not too demanding). Without the plastic globe?
I just compared (again) the warm 10w GE BS (unfortunate acronym) to the 9.5w Cree A19 (glass globe, not plastic "4Flow"). This time I was exactly 18" beneath the rim of the clamp-on reflector. I let both bulbs reach operating temperature (for 10 minutes). I measured 6" and 12" to either side.
The GE BS produces 22% more lux. If I removed the glass globe of the Cree A19, It might rise 22% (I tested that once.). But, the protruding tower makes the electrocution risk greater. If Cree made a light with forward-facing diodes, it might outperform the GS BS. But, given what's available, the BS is looking like a winner to me (in the household lightbulb arena, alternative to CFL, etc.).

im curious to figure out what a rough efficiency of the kind and solarstorm units are. i m sure a lot of it is how hard they are driven
the 2014 solarstorm '880' drives 176 "5W" chips at 600W total or an average of 3.4W per diode. I am unsure of the make of the chips
the 2015 solarstorm drives 288 3W osram SSL diodes at 600W (avg of 2.08 W/diode). ive been trying to figure out exactly which osram diodes these are but have not been successful.
my guess is the newer models are somewhere in the low 40s in efficiency, as a fixture, with the older ones being upper 30s-40%

40% is not that bad...it is like the best 1000w de system!...and all the light go directly on the canopy...it should allow to get gpw in soil...

Before CLW Used Osrams They Used Led Engine

ah i see 'led engin', never heard of them but they look like a larger OEM
heres their current offerings
more importantly heres their archived page of older models that would have been used in the 2014 SS880s
CLW's archived 2014 880 datasheet lists:
deep blue 440 nm
blue 470 nm
red 620 nm
deep red 665 nm
warm white 3100k
UVB 285-315
not seeing a match between those wavelengths and the LED Engin offerings.... also all of their single die diodes are 2.5W. its possible.... though theyd be running them on the upper end of their curve, like 2.9-3V each at 1100-1200 mA

Interesting video here that had solar storm 880 in it.
