@Ecosunlite - Dude, you are not getting it. Let me try to explain how this sort of thing works.
If:
you built a reasonable quality growlight case,
with 4 Cree CXB3070 COB LEDs that were carefully selected to provide a range of white light of the appropriate color temperatures and specified precisely the Cree 2, 3, or 5-step order code, (which unambiguously identifies the:
Nominal CCT
Minimum and typical CRI
Minimum Luminous Flux at 25 and 85 degrees C )
driven by any driver you like that could handle the required power characteristics of the Crees and came with a no-nonsense, 3-year warranty,
then:
a few of the characters on this forum would check the specs against the Cree XLamp CXB3070 LED Product Family Data Sheet.
If:
you got the specs right
Then:
Those characters would buy a couple of your growlights
They would test them
They'd get good results
They'd recommend your lights to everyone
You'd sell a shedload of lights
Everyone would be happy
Else
You'd get one more chance to get it right and we'd all start again
end if
Else
Your profile's 'Ignore' button will get more pokes than my bong's had tokes.
