Led Ufo Light - Not For Commercial Use

Hi All,

Just want to make everyone aware of my experience of LED UFO LIGHTs (hxxp://www.ggorganics.com/led-ufo-grow-light-450.html)

600W HPS vs LED UFO LIGHT (90W claimed to be as productive as 400W+ HPS)

10 PPP Clones under each starting at same state of health, hydro system. Im used to 600W HPS in these conditions so know what to expect, usually I get 1g/W this is my 9th Harvest.

Veg Period

Clones under LEDs much about a quarter shorter and half as thin as under HPS with lower leaf ratio.

Flowering period
Clones under LEDs after 4 weeks of flowing producing about a quarter of the bud ratio and leaf spread compared to HPS.

In the end I replaced the LED with an HPS otherwise it would sersiously impacted my usual harvest. When I changed tp hps they picked up immediately although will not catch up with the original 600W setup

If your a private user and hps delivers too much heat for your current setup then this may be the answer although dont expect too much - use flor to assist veg period.

If not then I do not recommend this product its a gimmic all the way to the bank.

Best of luck

how does this compare to CFLs?

Its much better than CFL's, but I agree with majogvet, they are overhyped at this time.

Now the Procyon100 is a real deal LED fixture, but even with these, in my opinion, it's advisable to use supplemental lighting.

For the last six months I've tinkered with CREE high output XLAMP red and blue emitters, actually my panels are roughly 70% red, 28% blue and 2% white, the white emitters are on each corner of the CREE XLAMP panel I made, the white Q5 emitters better helps the human eye determine the lights direction to the plants. I had to redo the entire first panel as I was making stupid decisions on the fly, the second panel was easier since I made all my mistakes with the 1st attempts, and I stopped being stuck on stupid

Before that, it was even funnier, I had two dozen red and blue CREE Xlamp emitters on Floral wire, each was very light even with the heatsink, they were all wired up using a bench power suppy and all the wiring looked like a spiders web, I attached each one to the bottom of the plant's stem, I used these for supplemental light to the neglected bottom foliage.

I also had two of those 15w idiotic 5mm 225led panels sold on Ebay. These are not even on the same league as a panel or fixture using CREE XLamps. Now for my last grow, I used a HPS cmh fixture, 400w of T5 and PL-L flouros, and my homemade CREE XLAMP fixtures.
I keep saying that LED's are the future for indoor agriculture, but just not today as high output LED emitters are in it's infancy. But even in it's infancy, the lights available are a bit overhyped, the only LED growlight that's actually worth the money is the Procyon100. Its just a well made and not hyped LED growlight, the proof is in the pudding and the Procyon100 delivers better than it's other LED competition.

For me, I'd rather build a multi emitter high output LED fixture rather than pay big bucks for one. But even when built yourself, the parts are not cheap, even in bulk.
If a person has a basic understanding of electronics, you can build something similar to the Procyon100, I believe the Procyon uses 42 Cree XLAMP blue and red emitters.
The cost of 42 CREE high output emitters is roughly $200 plus the fixture or panel cost, cost of resisters, wiring and misc supplies, not to mention lots of calculations because the red runs at X voltage, the blue runs at X voltage and the white corner emitters run at a different voltage as well. Plus lots of inhaling solder smoke, lots & lots of soldering

Here's the very first-ish CREE RED XLAMP emitter on a Floral wire, heatsinked and used on a grow in early 2007 It's a reminder of what not to do, heatsink was way to big, reflector was wrong type, and the floral string method had to go. Amazingly though, I never fried an emitter due to foliar spraying, that surprised me.

I now use it as a paperweight as it was my second CREE XLAMP emitter, the 1st one never made it out of testing, it blew up when I wanted to see how much out of spec it would run. (It was brighter than hell for the 2 seconds it was on, then went up in smoke as a offering to the Ganja Gods)

Anyone have pics of their plants onder the UFO, HPS, or CFL to compair???

thanks for posting, i was considering buying one of these, i love this forum

YouTube - LED Marijuana Grow

This should thoroughly explain the situation very nice documentary

I'm sorry I have never grown with LED's I have grown HPS and am growing, and also am growing a bit under CFL's in small quarters they keep up with my 400 HPS not equal on a small scale they don't have the penitration of the larger lamps. so my question is what kind of light is produced by the LED? Is it useable buy the plant? those are the two thing that have me wondering cause I know there bright
