LED lights? - Growroom Lighting - International Cannagraphic Magazine Forums

While at Menards the other day I saw some lights labled 'LED'. The box said they were for lighting work areas and claimed to be super bright and as energy efficient as fluoro's. Infact, they had some compact flruoro lights in a similar style(fixture) right next to them used for the same thing.

Are these LED lights good for vegging/cloning or would it be a waste of time?

thanks.

how many lumens?

did they require a ballast?

superbright means nothing if not in the correct portion of the light spectrum to be absorbed by the plants.

zero UV=no good

I don't remember the exact number for the lumens but it was definitely high.
I don't think it required a ballast.

Unless they are in the red or blue spectrum they are useless, lumens mean nothing for led's it is a specific wavelength (nm) that grows the plants. My taillights on my car are actually in the specific red wavelength to grow (flower) but it would be a real bitch to sit in the car with my foot on the brake for 12 hours.

I have seen LED growlights. Dont know if the lights your looking at would work or not though. Figure out the lumens and the color temperature and that should help. I dont think LED's get hot at all which would be cool if you could pull off getting some to work.

over on reeferman forums there is a chap who goes by the name "Cogitus" who has some ongoing experiments involving LED lights......he made them using parts all of which are available at "Radio Shack".....he has Red Lights and has added some Blue Lights.....i think he said the photosynthetic activity that LEDs generate must be measured in "micro-einsteins" and not Lumens so there is a bit of unit conversion if you are interested in the light intensity and the light effectiveness in maintaining plant photosynthesis..... -gp out

I like my analogy of it, growing weed with leds is like humping with a two inch penis. From a functional standpoint a guy with a two inch penis will tell you it works just fine where as every lady will tell you something quite different.

Check this thread out....just don't tell him he has a 2 inch penis, lol.

1344 LEDs using 90w power total and producing the equivelent useable lumens of a 500w HID. 6 strips of 224 LEDs, 15w each.

Funny, thanks for the link. The first two things I can tell you from the pictures is one, that that plant in the picture was initially grown under something else and put there [ I have seen plenty of led grows and yet to see one produce a plant of that size and color. ] and two, there aint no way that thing is kicking out the equiv of 500 watts of hid, just take a look at the second pic and see how dark that looks without the camera flash. Now does that area really look like its got 500 watts of hid equiv lighting it up? Hardly. The thing looks like you could develope 35mm film prints in it.

Now look at what the guy spent on it, " $135 per strip x 6 strips plus $120 for the power supply and $40 for shipping, total $970. " For that kind of money I could have got a 600 watt hid and had enough money leftover for 30 lap dances. Kinda funny the guy mentions the thing will pay for itself in about 2-3 years which is exactly around the same time you'll die from aids from selling your ass on the street for weed because your silly led growbox didnt work.

Theres a perfectly good reason a flo tube works better than leds, and a hid works better than flo tubes, and a 1000 watt hid works better than a 400 watt hid, and the sun works better than anything, etc. And thats because of the distance of usable light it throws out. And thats another reason why that plant pictured in the link didnt come from that light setup, its way too large and not the right color of green as any other plant I have seen grown under leds.
