On Some Led's There Are "dimminable" ?

[hawkman]

in a full spectrum led with that - it would turn the brightness down but the blue ,ect spectrum would remain the same ? so maybe it's best to turn the dimmminable to 50% elimimating the brightness spectrum ? thoughts ? or use to dim so one can put led closer to plant ?

Dimming just controls power not spectrum.
California LightWorks has a spectrum controller

looked at the california LED 550 ($799.00) vs KInd led K3 L450 ($789.00) and have to say California LED seem's better considering the "Solar System Controller" (extra cost $179.00) your thoughts ?

They had a pallet of them...warehouse buy? Not the sensor(greenhouse) model but the solar storm. What I am saying, I’ve witnessed that price. My wife bitched until she saw what retail was and the nominal bump in our power bill. Like I left alight or tv on.

Not sure about the others but I just got this one from Pacific light works. I really like it. PLC 6.2. Dimmable switch.

Dimming of LEDs does shift the spectrum. Most white lights use a blue with a yellow phosphor coating on top. When forward current is low, more yellow, but with higher amounts of voltage more blue light passes through the coating.
