why dont we collectively throw down for sphere data?

An LED’s spectral sensitivity depends on its color: they sense wavelengths shorter than or equal to their own emitted wavelength. This depends on the properties of the encapsulation; light from colors that it absorbs will not reach the LED.

qualitative vs quantitative....at the current pace which rules?, that's the more likely question :joint:
so basically are you saying lets hook up a 730nm to a picoammeter and compare to an actual calibrated photodiode?

i get it in concept but what response to they have relative to various wavelengths? most photodiodes are similar and with a good senseor youre not paying for hte photodiode youre paying for the corrected linear response (i do not know how they do this- whether thru optical filters or electronic circuits). also 20 uA difficult to measure accurately and picoammeters arent very cheap

s

someone like yourself with great skills would be good for that. if you got the space i got the chips. it doesnt need to be a commercial for citi or whatever. id personally like to see good consistent sided by sides of stuff like 80 vs 90 cri etc. most spectrums are similar from mfr to mfr anyway.
I guess I'm going to have to make room for a proper test.i would need 3000k or 3500k chips and similar in watts to what im running now which is 15 x 2700k and 15 x 3500k crees.does citi make 2700k chips like this?

those are awesome the only thing that bugs me are relatively low efficiency of those little dc drivers. great for supplementals for sure but i would hate to run a whole rig like that

also you can install a small connector to the storm controller and it will also control your big drivers as seen in the pic doing the HLG320 DRIVERS. You can upload weather data from anywhere and it will replicate that weather

happy to report that its sunny and 85 in my garden today - its like hawaii without the rain!

Would need them to be 80cri to be fair to my cree 80cri.can i run them at 35w without a bunch of trickery lol.whats the voltage of those?
1818s are the best match for the cree watt for watt. they are 50V chips so same deal you just run em on a 1050 driver beside a cree at 1400 and the watts come out almost the same to where you could dim and match

yeah. +/-

ive never tested an 1812.

robin says they replace crees the best.
in my testing the 1818s replace crees the best

in reality over a bin range the cxbs are probably between them

ill have to do a side by side with 3500k 80cri in both. my 4000k tests are faulty because the cree is only 70cri and nobody sells the CD bin 80cri in 4000k. so the crees have a handicap in that test

1818 will always be more efficient than 1812 due to series/parallel diode array configuration

i chose 4000k 80cri because those are easier to get across the board, i wouldnt have been able to test the getian or new vero (yet) if i did 3500k

that one control which has a cell phone plug to power it up, and is pwm dimming all on separate channels . I power these far red bars with it. and my two HLG320 drivers. once the Mega control is built it will have 64 channels with the Atmel proceser doing really time temp control , light control, PH control, co2 control. and any other thing you demand out of a environmental control.

sounds thread-worthy!

Idk where 1812 came from,I was talking about the 1818 on a mw 700ma driver vs cree3590 on a 1050ma driver because thats what i run now (1050ma) hell i could just use 1050ma and dim down till the par # match seeing as i already have a bunch of 1050ma drivers and a fancy par meter :)

thank you we should start that. because done right this is the control of the future. but I'm doing it from the ground up because at the end of the day what every grower wants is a fully automated environmental control that you can control and see with your phone.

I Run The 1812's And IMHO It Really Makes No Difference Between The 12's,18's And 25's. Its Like Which Hortilux You Want The Blue The Super Blue Or The Eye:weed:
