Lighting Switching from HPS to LED

[jaymu104]

Ok so here's the email they sent me

Here's the footprint and coverage for our entire line


PAR:


SolarSpec100: 1007umol@12", 496umol@24", 240umol@36" flower: 24" x 20"@18" veg: 24" x 24"@20"


SolarSystem400(4 x SS-100): 1315umol@12", 855umol@24", 522umol@36" flower: 3.5' x 3.5'@18", veg: 4'x4'@24"


Solarspec150: 589umol@24", 396Umol@36" flower: 2.5' x 2'@20", veg: 3' x 2.5'@24"


SolarSystem 600(4 x SS-150): 1236umol@24", 810umol@36" flower: 4' x 4'@22", veg: 6' x 5'@24"


SolarSpec260: 1168umol@24", 685umol@36" flower: 3' x 2'@22", veg: 3' x 3'@24"


SolarSystem1040 (4 x SS-260): 1730UMOL@24", 981umol@36" flower: 5' x 5'@24", veg: 5.5' x 5'@28"


SolarEclipse250: 1600umol@24", 870umol@36", 503umol@48" flower: 3' x 3'@24", veg: 3.5' x 3.5'@28"


SolarEclipse450UVB: 1387umol@24", 1130umol@36", 750umol@48" flower: 4' x 4'@24", veg: 4.5 x 4.5'@28"

Mine is the last one n I stand corrected mines is just under the the sun really n spectrum is the closet to sun n most fullest but the have the pro8 which is 2114ppfd @24" that's my goal for next year

But they refuse to disclose the data about its light output.
Like buying a racing car with the manufacturer not telling you how fast it goes...

If you can imagine DIY (not very difficult). You get by far the most bang for the buck.
Check growmau5 guides on YT.

So with you on this

I stand corrected, but those Solar Storm numbers are just as bad.

"SolarSpec100: 1007umol@12", 496umol@24", 240umol@36" "
If you put a meter directly under it, you get these numbers.
What does it tell you?
Not much/ nothing.
Bc these numbers are dependant on how the light gets focused down. "Stronger/narrow" lenses = higher value.
Possibly you could measure 1000umol directly under it, then move the meter 10cm and you get only 100umol...


What you need is a footprint of 3x3. In that footprint you need a lot of measuring points at different locations.
With a visual footprint you can plan for your plants.
Or from those numbers you can build an avg. for one sqm.
Like this: PPFD 3’x3’ avg: XY µmols/m^2/sec
And then you can compare...

On that page they do a comparison which shows the methodology you described. So @jaymu104 you should peep the video I found it interesting.

Happy holidays guys hope your having some quality family time

Yes.
If you then compare the 24" footprints given in that link to that of an CMH also tested by Growershouse at 24" in 4x4...
http://growershouse.com/images/ALTEST_infographic_1.pdf
Then relate those those values to the draw wattage.
At 1 feet width the led averages about 180. Led draws 200W.
The CMH about 390 and 350W draw.
Calculated down to a draw for 200W too for the CMH, the CMH would give about 222.
I mean this is super simplified and maybe I made a mistake there. But if I also look at the 3x3 values and 2x2 those leds numbers in comparison to the cmh neither seem impressive nor gamechanging.

Those are the solar flare leds? Kinda the baseline led model they offer. I have an 880 and a few 440s and they seem to do a great job and I can't complain. Plus I had a diode go out so they shipped me a new light with return label to avoid downtime. At the end of day it's a sales teams job to push a product

True but the ppfd reading at its edge is 600 @24 inches so I think those numbers are great plus it has one of the most complete spectrum any where look at the sun spectrum and check this out

 

[jaymu104]

Plus look at their website they lack a lot of info so that should tell u something

 

[jaymu104]

Plus I've always wondered wat mutations come out of such an unnatural spectrum of so much blue n red since plants have evolved to use all of it

That's purely speculation unless you've been able to do a controlled study to prove a mutation had even occured. An interesting thought though . does your light set up have a UV spectrum? The sun emits uv rays as well so you'd have to account for that in your mutation theory as well.
