ledgrowlights.com— LED grow lights combine the gentleness of fluorescents with the growing power of HIDs. They also produce very little heat. Save 50-75% on power over HID lighting. They last for 7 to 10 years.

Not cheap. $350 for a set of two red one blue lights on a track light fixture. 50,000 hours recommended useful life. 22 watts of electricity. If someone was smart with this stuff, maybe they could figure out how much they save energy, and if they could actually save money.
I'm no grower, but I'm surprised the cops haven't knocked on my door with my power bill. With all the PCs and TVs and other gadgets my bill is over $200 a month, when it should be closer to $50. P.S. I heard you can block the heat sig of a hot room by using aluminum foil. Don't ask how I know that.
Uhh yea. I'll believe it when I see a spectrum chart or even something listing lumens. In my experience there's no way that small amount of LEDS in each fixture can put out nearly as much as a 1000w HPS HID. I'm calling BS for growing pot at least until I see one or the other, a spectral analysis or a lumens rating.
The light output for the power consumed on an LED is very efficient which is why the little flashlights last so long on a set of batteries. The cost of these is outrageous though. I am waiting for microwave sulfur lighting to become available to the general public on a reasonable scale.If anybody is interested in the real future of lighting check out this link. <a class="user" href="http://www.space.com/businesstechnology/technology/light_farming_010926.html">http://www.space.com/businesstechnology/technology/light_farming_010926.html</a>read down through till you get to the part about microwave sulfur lighting.My plants aren't illegal but I have a small child and she has cats that like to do nasty things to plants and also most of my plants would do nasty things to them and my kid so I have to have a separate environment. Also two plants that I plan to order this year are native to alpine regions and the lack of excess heat will be a real money saver since I will have to basically build an alpine environment for them. A hundred to a hundred thirty bucks for ten SEEDS when a single plant can produce 5 - 9 hundred seeds is well worth converting a couple of stand up freezers with light, CO2 feed, drip irrigation and modified thermostat control. grins I love LED lights.
Using any light source that in effect burns a wire to create light as in Sodium or halide is gramophone technology. LEDs are far more efficient, also what you have to remember is plants do not use the visible light spectrum that we humans use, they photosynthesize using red and blue light. And another point to consider if your going to talk about lumens is that an LED array would not fry the plants when you brought it closer as they generate hardly any heat, and as you know if you bring a light source closer the inverse square law comes into effect and the intensity quadruples. I have worked on this science for years and I can verify that it works exceptionally well. You can build large arrays to cover any size grow room you desire as long as you get the Red to blue LED ratio correct as too much blue light will actually kill a plant, you should use no more than 10% blue. Any body interested can email me and I will guide them in-depth.
LED grow lighting has other advantages besides efficiency, think about this scenario: A semi-automated system with lights and pumps on timers that requires human intervention only every third day. The pump timer fails. Under 1000W of halide heat, 3 days without water = dead or dying plants. Under low heat LEDs, 3 days without water = wilted but entirely salvageable plants. Also, if you grow with arrays of red and blue leds, putting a couple of high brightness amber leds at the far end of the room (next to a couple of glue traps) will prevent infestation with whiteflys.
Hello! I wanted to introduce myself, my name is Greg George, and I am co-owner of Groovygrow.com. We offer a line of high intensity LED grow bulbs you can see at www.groovygrow.com. Please feel free to see our page by clicking this link. I think you will find that our products are the highest quality on the net to date, and the most affordable. Great Technical information available on our get info page. Have a look! Greg
I am afraid a correction is in order here. Traffic light bulbs are on a close but not quite right wavelength of red. Check out the "Get info" page in www.groovygrow.com. Every statistic needed is there. The wavelength for plant growth and plant bloom stage is also different. Greg
First off a 1000watt is good for about 50sq ft or 7ft x 7ft. A good grow bulb is $110.Good for 6months.So lets say you run 3 lights.That,s $660.00 a yr.LED good for 7.57 yrs.So it would cost around $5000.00 in grow bulbs for that time.You need 20 watts per sq ft with led light .Well most plants need at least 4sq ft of light.You looking at least $400-500 per plant. Say 30 plants.That's $15.000 not including sockets ,cord etc.Now if you need 80-100 watts of led light per plant that's the same juice as running 3 -1000Watt bulbs .With out the extra cost.
I just wanted to add that in many situations.Without the heat from grow lights your room might not get warm enough.You think you wont have to water as often but dirt that is wet for a long time is no good.You get fungy and root rot.Kinda like the sun coming up but with with no heat.
I have seen LEDs for reef tank use on line at <a class="user" href="http://www.LunarAccents.com">http://www.LunarAccents.com</a> , but I would really like to fabricate my own custom light for personal use! The engineering fees at places like Lunar Accents Design are just way too expensive for me!!
Hey Rcmagoo great stuff here. I am wondering if you have any further instructions on how to assemble and acquire the needed parts for those lights. And specs and instructions would be greatly appreciated! creo47@yahoo.com is my email. Thanks in advance and I hope you get this!
There is a lot of misinformation out there about LED grow lights. I sell them so I know a bit about them after lenghty testing. Our new GL 103 grow bar features 228 LEDS (red, amber, blue, infrared and one green for plant viewing), uses 12W and covers about 6 sq.ft primary light and more with peripheral light. We only sell 3rd generation LED lights which last 150,000 hours and have a 15 year replacement warranty! The output in microEinsteins, which is the available light for plants, is higher than a 600W HID lamp. Lumens or FC are useless because that does not measure the light available for plant absorption. Typical savings in power consumption is 90 to 95%. No heat, no ballasts, no replacement bulbs for 15 years, and 100% available light for photosynthesis! It's a no brainer.
Where can I get the lights? Are there any larger ones? Do you honestly feel that these LED lights are a better way to go, instead of the regular lights that we use to use?

you could also buy a couple red traffic light LED modules (15watts) from a place like <a class="user" href="http://www.trafficlightwizard.com">http://www.trafficlightwizard.com</a> for 25 bux (they are REALLY bright) and a couple of blue MR16 type lights (or comparable) from <a class="user" href="http://www.superbrightleds.com">http://www.superbrightleds.com</a> All that's a lot cheaper than $350... now if what you're interested in is the track light fixture... those are less than 50 from good old Home Depot... :P
