LED grow lights... input please.
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.

oldsanclem Reviewed by oldsanclem on . LED grow lights... input please. Hello guys, I'm exchanging eMails with a representative from a LED company. I asked him if they could produce a custom light for growing, and here's what he told me: Our options are as follow: 940nm, 850nm, 660nm, 630nm, 610nm, 590nm 570nm, 530nm, 510nm, 470nm, 460nm, 400nm and a total of 64 LEDs in the bulb.

The reason why you donā??t get a red from what is called a white LED is that there is no red light in the spectrum (hence your filter cannot filter it out as it isnā??t there to begin with). Its really a blue LED with yellow phosphor (thatā??s what I've learnt). Interesting experiment though! I donā??t see how that could affect the chances of LED plant lighting succeeding? LEDs usually donā??t emit a wide spectrum because of the way they make light. That is an advantage in plant lighting, as plants only use certain bandwidth of light energy, so what you said is actually an advantage for plant lighting and is not a problem at all really.

if you want red light on your car's break lights, I would use red LED's that emit red light. With ordinary lighting, your having to filter out all those colours apart from the colour you want (i.e. red) - highly inefficient! with LEDs you just get that one colour you wanted emitted right from the source itself ā?? no need to filter.
Hope this helps.

L.E.D. lghts work very well in my opinion. i have a couple green star grow bars and some red l.e.d. panels for side lighting. they cost some xtra money but they work incredible for vegging (greenstars) and the red panels make an awesome side lighting for fat lower buds when used with my 430 hortilux i have gotten the fullest buds from top to bottom when usually my bottoms were quite stretchy in the past. all of the under branching thickens up amazingly adding about a 10%-15% overall yeild to my plants. wich is quite a bit. i would reccomend using leds bottom line.

I was thinking of incorporating LEDs with CFLs. LEDs for side and bottom lighting due to there low heat. CFLs up top.

this bar is supposed to be equal to a 250 watt but uses 12watts i got 2 and 2 red 25 bulb panels for side lighting that use like 15 watts or somthiing, with my 430 watt hortilux so my flower room uses around 460 watts but i get around an 800 watt light output. i think if you have the extra cash you should buy a few just so you can see..
