 LED light

I'm looking to get an LED light system in order to save money on the electricity bill, I was wondering if anyone could point me in the right direction as for selecting something worth while. Somewhere less than $200 would be nice.
I've never grown, but looking to get about three plants. Thanks

Search ebay for 120 watt grow lights, you should be able to find a nice one fairly easy.

I love my LED, it's only a three band but does great.
As for replacing a 600 I don't know about that.
I can match my 400 HPS yields tho with out problems.

What's the deal with the direction, 90º on that one i posted. would you recomend that light? i'm drawn to the made/engineered in usa aspect
also, what about 1w vs 3w led's?

Higher wattage the better penetration you'll get.
I haven't played with a 5 band yet, tho it should do better than my three band setup.
That light is made by the same company as mine so I guess it'd be a legit unit.

So if I had that light for example, what could I expect in yield? how many plants would that sustain in soil?

To many viables to say honestly.
It'd greatly depend on strain and grower ability.
But a good grower, who knows his/her strain could easily do 1 to 3 grams per watt.
I wouldn't use that unit in an area over 6 square feet with high expectation either, less of course less would be better.
In my experience, experience is the largest key to yields.

...really ,how is the rate of growth , is the veg time slower with the led ,or is the veg time the same as a hid lamp? does the 120 watt led cover the same sq footage as the 400watt hid?

I noticed during veg growth the limb spacing was closer, making a tighter looking bush. Other than that not much difference in the two systems.
As far as coverage goes, I wouldn't go beyond 6 square foot for either system. So I guess the anwer you're looking for is yes.
I'm currently letting a friend use it, along side of a 400 HPS in a 2.5 x 2.5 x 5 foot space, he has just started week 5, day 29 of slowering and this is what it looks like.

They are not that expensive, about $200 for a 120w light that is roughly equivalent to a 400w hps. I'd say that's a good price for not having to swap out bulbs or pay for the extra wattage. If it produces one ounce in its life time it pays for itself.
I was looking at a switchable hps/mh lamp that was maybe $20 less but did not come with the bulb.
Another thing that appeals to me is the lack of heat. I'm sure HID's are perfectly safe and all, but i'd rather not risk burning down the apartment. Oh, and this is just a stand alone light that will quickly be ready to be thrown in a box in a jam, without having to let it cool.
on order:
light contains 112 x 1 watt LEDs, red/blue/orange/white 19:3:3:3 ratio

The light I ordered was out of stock.. any comments on this light?
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290533637583&ssPageName=STRK:MEWNX:IT
from the graph's i've seen it looks like chlorafil a needs those violet colors as well as red. this is one of the few that has those extra wavelenght's, but i'm wondering if i should also suppliment it with maybe some panels or something like that.
obviously more light is better, but does anyone know if those 14w led panels are worth a damn?
like this for example...

Those 14w panels are jokes, they'd only be good for side lighting in my personal opinion.
That other unit looks like a nice setup, tho.
One of the biggest points to check for is wattage per bulb, you want at least 1 watt per bulb, tho I'd prefer more.

watts per bulb is why i went with the blackstar. it uses the 3w led.
and yea, i was thinking about maybe supplementing that blackstar with two of those panels, but never as main lighting. $67 for two doesn't seem too bad of a deal, but the 14w aspect really leaves me skeptical. I think it might be better to just save up for another blackstar in the long run.

People buy them direct from China. It's the best deal and you can custom order the spectrum, get the latest shit. Kinda a bitch but it's worth it. Otherwise buy a used one on craigslist.
Tons of fuckers grow budz then bitch out. Tons of LED's out their that work just fine and will for a long time. As long as they aren't first generation, they work well. Even so if it's first gen, just use it for veg and buy it on the cheap.
Knowledge is power, research the shit before you buy it. Any used 3 or 4 band is good enough dude. I had some cutting edge shit for a minute, 3W led's and shit but I'll reinvest soon.
I might even deal with these fuckers myself and start a small business for cutting edge LED's. Once you know the knowledge, it isn't that hard to know what to get. eBay is lame. Don't use them man. They rip you off for not having the knowledge to start your own business or cut out the middle man. Running a business on eBay is weak sauce.

Here is plenty of them to buy. Almost all the distrubters here on eBay order them from china in bulk. I bought ones from different suppliers and they all sorta worked the same. Here I search for 3W led's.
http://shop.ebay.com/i.html?_nkw=3w+led+grow&_sacat=0&_odkw=300w+led+grow&_osacat=0&_trksid=p3286.c0.m270.l1313
I looked at the cheapest one from http://myworld.ebay.com/ledstores/?_trksid=p4340.l2559 and it looks legit. Unless you find one used, or start your own business from China, that is the best LED light you are going to get for your money today.
Hard to invest, since every 6 months they make something better. But mostly they have stuck with 3W led's and 4+ bands as the cutting edge of LED Grow Lights on the market. Bridgelux are the cheapest LED's and CREE are the best. I used a combo one just like the one this guy is selling and it was amazing for either flowering alone, veg alone or in combo with HPS in flowering was super awesome!
The prices now are even cheaper then they were 6 months ago. It will get cheaper in another 6 months but damn those 4+ Spectrum LED lights have UVB LED's which kill mold and are awesome for plants. Those LED's alone are worth it in any flowering room, period.
The simple and very cheap led's that are only 2 band can work for veg, Red and Blue but you might as well go for a 4 or + more band unit. I had a 120W unit from eBay that had 1 watt led's and it seemed to do pretty good in a 2x5 area, even though 2 of them would have been better. The 120W unit is almost as powerful as a 400W MH for veg. I'd say plants respond better to a 120W LED 4 Band Unit vs. a 400W MH.
For flowering I never got to try just LED's, I used a mix of HPS and LED. The unit I had was crazy futurist, but cost a premium at the time. Had at least 8 spectrums. Right now is half the cost of 6 months ago. By 2012 I think LED's might just be cheaper then HPS or MH for even 1 bulb cycle. I mean right now it's about $1 a W.
Only thing about LED's is they are slightly tricky. Make sure you ask the supplier what the W draw and output total is of the unit. Once some crappy company said it was a 600W LED unit, when the draw was only 300W and output was only 300W. Regardless the actual number, I find the real world output in comparison to MH and HPS is roughy 2.5 X W of the LED Output. If you get that much LED instead of HPS or MH I'm positive it will walk all over them if you plants are trees.
With the 3W led's light penetration goes at least 2-3 feet. At time goes on, it makes no sense to buy at least MH lights as LED is essentially superior to them considering plant height isn't ridiculous. Even with ED Rosenthal says LED's are the future; indirectly of course. He states that UVB lights provide many benefits to cannabis plants. Ironically they are only found in LED lights to my knowledge. http://mjgrowers.com/book_what_exper1.htm http://www.420magazine.com/forums/cabinet-closet-grow-room-setup/79209-uvb-light-whats-real-story.html
Infrared LED's are the same thing as a UVB LED. Where Eye protection if possible.

Ummmmm no 
Infrared : 700 nm - 1 mm wavelength
UVB : 315 nm - 280 nm wavelength
Infrared Radiation (IR) is a low energy form of electromagnetic radiation that has a longer wavelength than visible light. If you put any IR emitters in your grow area the only thing that will happen is you will burn your plants and the cooling load will go way up. The only thing IR does is heat shit up, and changes the channel on the boob tube.
Ultraviolet Radiation (UV) is a type of EMR that has a shorter wavelength than visible light. Lower energy forms (UVA) are emitted by blacklights and are essentially harmless. Higher energy forms (UVC) are used as germicidal light that can sterilize exposed surfaces and causes severe damage to live tissue and organisms with prolonged exposure. The form b/w these two types is known as UVB, and is responsible for the burning effects of the sun. Since UVB can cause direct DNA damage, it is hypothesized that the cannabis plant (prone to grow in regions of high UV indexes) has evolved a natural "sunscreen" (THC) to protect the little prodigy that are produced in the calyx. THC is a very good UVB reflector/absorber, and it's precursor compounds actually utilize UVB to form THC inside the trichome head. A little extra UVB in the grow tent during flowering can stimulate trichome production and an increased rate of THC production. It can also slightly speed up the process of THC degradation into CBD, but it is the general consensus among many growers that slightly higher (3-4 hours of UVB reptile light exposure during the middle of the day period) levels of UVB exposure usually results in higher trichome density, and thus a higher level of THC.
UVB LED's are way more expensive than IR LED's, and ARE COMPLETELY DIFFERENT DO NOT BUY INFRARED LEDS AND EXPECT IT TO PUT OUT UVB.
Infrared will not cause direct DNA damage unless your skin is blistering from 2nd degree heat-related burns due to super high intensity IR exposure. UVB causes direct DNA damage to exposed skin and clouding of the lens of the eye (cataract). This means you need to have a killswitch for the UVB light in ur tent or protective eye wear before entering your grow room.
Sorry for such a long post, but blatant misinformation involving LED technology calls for justice. As always, I'm just trying to help.
Peace,

Well Agmotes already (correctly) called you out on the UVB vs Infrared thing, so I'm going to leave that alone.
However, UV is NOT just found in LED's, that's just absurd. In fact, UV wavelength LED's were the LAST thing to arrive on the market in terms of sub-visible wavelength bulbs. I have multiple Incandescent UVB bulbs, some VERY high output UVB CFL bulbs (reptile lights) and yes, both HPS and MH bulbs produce UV wavelengths in varying quantities.

That is also very true and while I love growing with LED's I must also state that in order to maximize yields a small amount of full spectrum light much be used in conjunction with the LED's, and I just go buy the high UVB output reptile CFL's and put one or 2 per grow tent. I have no real world experience with UVB LED's, nor do I have any intention due to their extremely low efficiencies and extreme relative costs. My understanding was that both MH and HPS produce so much UV initially that a UV filter coating is applied to the little tube on the inside just to get the UV radiation down to a safe level. I know the mercury vapor lamps only produce UV and a phosphor coating is used to absorb the UV and re-emits visible light.

Whoops. Thanks for the clarification between IR and UV, and the etc about the HPS and MH having bits of them. I guess between the group of us, it helped out a lot.

So i went home for a week and left my three plants chillin, and took the seedlings with me, ditched half of those, but picked up some good plants, two white widow clones I took and an afgan kush rider
afgan Kush Rider - Autoflower
   
So two of the plants streched out a bit while i was gone, I turned the CPF's off while I was out of town since I didn't have anything to control the temperature of the closet, which can get to atleast 85ºF. Also didn't water them for 7 days, but they all appear to be fine, with the exception of one branch that just went limp while i was gone.
My main concerns are what type of watering cycle should I put these on? I was watching a video where the guy was doing 200ml every other day in veg, but that seems like it might be a little excessive.
I also got some nutrients, advanced grow/bloom/micro, tarantula and pirhana microbes and was a little curious about nutrients with an organic soil. I thought i read somewhere that you can over fertilize organic soil, or should I just be fine going with what's on the label?

Infrared LED's are the same thing as a UVB LED. Where Eye protection if possible.
UV and IR are at opposite ends of the "visible" light spectrum. They are not the same.
UV-A 315nm-400nm wavelength
UV-B 280nm-315nm
UV-C 100nm-280nm (germicidal)
the UV (ultraviolet) part of the spectrum ranges from as short as 10nm up to 400nm (UV-A)
IR is Infrared and has a much longer wavelength and is mostly invisible to our eyes, although bright IR sources can damage the eye.
We feel IR radiation. It is heat. The IR part of the spectrum satrts at 700nm and goes up to 1mm in wavelength.
IR-A 700nm-1400nm
IR-B 1400nm-3000nm
IR-C 3000nm-1mm
I am talking to a chinese mfr. there is a thread I started called "perfect LED panel" you can check out the details there.
price looks like its gonna be pretty good, and no minimum order 
I edited once I read the rest and saw that someone already mentioned the UV/IR stuff
