Would it be okay to put 2 screw in 168 LED bulbs into a rubbermaid that has the lid on it instead of another rubbermaid bin? The lights would be flush with the lid above and out of the box.

i read about the led ufo, they sound impressive. kinda like cfls to incandesants
Oh i know they work well, I just dont know if thats too close.
Any more input would be appreciated.
If it doesn't come with any mounting bracket. You need to manufacture one. When plants grow and when they are small need to ajust light distance. Wouldn't mount light in fixed position, it will be either to far or to close and piss you off all the time. Keep thinking about it before you do anything, something will come too you. Maybe a picture to see what you are trying to accomplish? Just sounds to confined of space to start with. The led's will work for you. Would still supplement CFL cool white or day with it. Hope this might help. Later
You can pretty much touch the plants with L.E.D.'s. Is that all you plan on using for lighting?? I don't think you will be able to grow nice healthy plants with L.E.D.'s. Your much better off getting some cfl's if your tight on $$$.

If you live in a newer home, look up. See those light fixtures your floodlights screw into? I plan on buying 4 of those(all I can fit) and putting them onto my lid. Ill cut the holes smaller than the lip and just seal them on with seal-all. Then I plan on usin a normal 110V screw socked to put in the top for the lights.
So If you can imagine it... the light housing will be OUT and BOVE the box and the very surface of the bulb itself will be just as high as the lid would be.
Also NorCal, I was going to probably use 2 LED's 138Red/30Blue, and 2 of the highest wattage Soft Whites I could find. I got some actual output 26W right now but for that little rubbermaid... I think it'd do the trick. Maybe just ONE LED and THREE CFL's?
Pics are on my scrogging box thread.

Figured-out how to properly ventilate it yet? Even if heat isn't an issue, the ladies need fresh air and a little breeze.
cfls are great light for money, i agree. however, leds are becomeing more and more efficient for growing and flowering. HIGH TIMES reviewed the ufo (90w) vs. a 400w hps lamp, and found that the ufo yielded more bud, healthier plants, and even a slight increase in resin levelsQuote:

Unlike HPS, can you put an LED light within inches of your flowering plants then? Thats my main question. Will the light from the LED be efficient even within less than 6"?
yes
The only problem with that distance with LEDs is the blues and res don't blend very that close. We have three Procyons 24" above ours. Still seedlings though. They'll be about a foot closer during veg depending on stretch.
Glad to see some more LED believers. I've also seen in two other led grows where they claim higher potency levels, and isn't that what we(smokers) all truly want.:smokin:
edit: but the bulbs might be packed tighter in the screw in models. so what do I know... lol
one day i think ill upgrde to an led system. my hps is still new though, so its gonna last me many years yet.
someday though, i will definitely look at upgrading my cfls to an all-blue led panel

Can you find a link to this?!? That is completely unbelievable to me. L.E.D.'s have an aplication, just not growing. Also, the ratings some manufatures give on their "super-high output" L.E.D.'s are almost lies. I looked around a bit and found a prototype white LED supposedly achieving 150 (Lm/W). The rating they gave it was VERY misleading. You might notice that it was rated using Lumen's per watt of light output, not per watt of electrical input. It was emitting 420 Lumen's at 8-watts. Witch is 52.5 (Lm/W) by my math. :wtf: They are trying to show some advancement, maybe to get some government funding?? Like wind and solar maybe???
Here are some Lumen's per Watt of common bulbs:
Candle : ~.3 (Lm/W)
Incandescent : 20~24 (Lm/W)
Halogen : 30~36 (Lm/W)
L.E.D.'s : 26-70 (Lm/W) The high of 70 is for prototype white L.E.D.'s
CFL's : 45-105 (Lm/W)
Sulfur Plasma : ~100 (Lm/W) light output VERY close to sunlight, better than any other artificial light source.
Metal halide : 80~125 (Lm/W)
High pressure sodium lamps : 140-160 (Lm/W)
Low pressure sodium lamps : 180-200 (Lm/W)"
Make up your own mind on them with this info. :greenthumb:

we are tryin to give everyone a definitive LED grow norcal
alright guys....these pics are one week old sprouts. lookin good so far, had a few stretching a little bit, but just moved some pots around and they are fine.....

got 3 procyon 100w running these
L.E.D.'s : 26-70 (Lm/W) The high of 70 is for prototype white L.E.D.'s
Thats old news I see once in a while, where do you guys have this from?
Cool White Luxeon Rebels have 100lm at 350mA, 3.15V thats roughly a Watt.
Cree is the same, min. 100lm/W
No prototypes, available to order.
Norcal that article was in the newest issue of hightimes i'm sure its on their site or the store shelf.
as far as lumens go were getting an even 4000-5000lm in the correct spectrum across our room at 16" up and performing wonderfully.
Blumen are you looking for individ. LEDs or a lamp?
you dudes are all on the wrong thread. "Indoor growing" ..."LEDs Input please"
Thanks, I'm going to get the new issue and read up. Hope they only used L.E.D.'s, not add extra non-L.E.D. lights. I hope you guys are right about this L.E.D. stuff, I could use a smaller power bill. :D
check out our thread for an all LED grow nor cal....i think this thread moved too......
