LED grow light, what do you guys think?

Ok so I found a company that makes pretty good LED lights, here are some of their claims for the light. It's either this or this 400w lumatek system i found online that has the interchangeable HPS n MH bulbs. Ok so here are the specs for the LED light.

[FONT=Arial, Helvetica, sans-serif]Features[/FONT] Input Voltage - 110 +/_ 10% 50-60 hz
Power Output - 120 Watt (More powerful than a 500 Watt HPS)


LED Configuration - 112 x 1.07 Watt LED, 100 Red + 12 Blue
BridgeLux Blue LED (USA Made)
Lux (center) - 118 Lux/2.5m 55 lux/3.5m
Lumen - Approx. 3600 Lm
Lighting Coverage - 12 SQ. FT +/_
Lifespan - 50,000 Hrs
LED made by BridgeLux (USA)


WaveLength - Red=630nm, Blue=452nm


What throws me of is the amount of Lumen. 3600?!?!?! thats nothing, is that correct or am i missing something? I wanted something with atleast 20,000.



And the Wavelength, anyone know if those are the optimal numbers for photosynthesis?


All the help is greatly appreciated.

Forget the LEDs and just go with the 400W HID. Leds might produce the correct wave lengths, but nothing can make up for the lack of lumens.

I'm growing with a 400W HPS and they girls love it. If your worried about power or heat, go with CFLs, I've seem fantastic grows using only CFLs.

ive use them they work well it can be done

do you have any pictures of your grow? i plan on using w/e light i get with a bubbleponics system only growing four plants tho. I plan on topping and all the goodies. Is the yield comparable to that of the HPS?

Dont waste your money. LED's will get you low yield and light fluffy buds. You won't like them. It's more effective to get a 400 w HID switchable unit. You can use the mh bulb for vegging and the hps for flowering. It's way cheaper and it works best.

Dude if u wana grow with led lights then go for it. They have there advantages wen your comparing them with hps. check out the link, it seems like led lighting is the future.

Notice that link has no information about lumens? It's been tried and proven that while stuff may grow under them, is no where near as good as a hid or even cfls for that matter.

I would go with an LED/CFL combo. CFL has the right spectrum and wrong spectrum. We know red and blue work. Mix CFL with Blue/red LEDS. You get more light in that spectrum.

When evaluating the benefit of LEDs don't pay attention to lumens. Lumens is a measurement of what the human eye can see. Instead, focus on the PAR value. PAR is a measurement of what light plants are after.

very good point.

www.g2led.com I am using the HLS120. So far it seems to be doing great. I have been on 12/12 for about 12 days and the buds are starting to appear. I would say just check out all the other grow journals to see which one does the best in flowering and go from that.

Leds buds are fluffy and FROSTY, have u ever smoked an LED bud and compare it with HPS grown Bud? I average half oz a month with top shelf medical HPS grown weed and the LEDs, 3 hits and im high as hell for hours and the taste is like more stronger that 7 grams of it will last me a month. LED yields are bad but if ur just an average joe who medicate with only the best LEDs are the way to go. U can even mix them with HID/CFL and they will be big like hps buds but super frosty if yield is wat ur concern with.

LEDs do a super job on vegetating probably as good or better than HIDs, flowering is the weak point of a LED, but that is rapidly changing as the upper end companies are working on wavelengths of the LEDs. I have heard of some super good results coming out of some of the bigger ops in Amsterdam. Sounds like you need to keep the lights as close to possible (7 to 12") on the plants during flowering to keep the buds dense. One possitive I have been hearing is that LEDs are producing some super dank smoke and THC levels are sometimes higher than HPS. I think the best of both worlds right now would be LED for Veg and HPS for flower, but that's not in the budget for most of us. If you are serious about LEDs then save your money and buy a good light and not one of the cheap Asian Import UFOs or panels (expect to pay over a grand). Check out LUMIGRO for example. They and Solar Oasis are some in the top nitch in the Industry and need to be watched carefully in the future. Personally I am excited about the prospect. But at the moment Im not willing to give up my high yields that I get from my HPS yet. I do believe they are the future though.

Here is a link on a LUMIGRO journal grow. Dont see alot of aired out popcorn buds on this grow, infact just the opposite.
