The bright red tail light is a very narrow spectrum. I have tried to use a white hight output leds in a tail light. Installed it in to the tail light. Put power to it , and no light came out the red lens. Reason a White led does not produce a spectrum of reds. NOW all the leds red, blue, green etc are all that way. Now if you look at the spectrum of growing its a smooth arc. NOT (freq's or angstroms )
IF leds worked it would be all over the internet and in every industral user would jump on them faster than a duck on a june bug.
O WELL back to using 30 year old florsents 4 ft bulbs and a 30 year old Mh ballast and a new bulbs.
O lord I see the light, zaaaaap , darn its a bug zapper.
Now think if LED did work effeciently industy would use them in a heart beat. After all its only a few Billion dollars saved each year.
Do pot grower know something industry does not know.
Bottom line my fairy godmusther is a whore and charges for her favors. imp:
