We have comparison grows starting soon using the 63W against a 90W UFO from Sunlight Hydro, our 126W against ProSource's 180W Jumbo UFO, and two 63W's, against a 150W LED bar.
We have Ed Rosenthal doing a side-by-side test using 954W LED vs 1000W HID, and the two gardens (myself and my friend) I've been posting results of.
My next test will be a stand-alone run with the 126W, to show what it can do on it's own, with 4 plants in hydro.

I think we all can be appreciative to the work that is taking place here. I think it is wonderful. We can almost certainly say by the year 2010 we will have an LED light that has proven results.
Thanks to your posts, and everybody involved in this process. Keep us informed.

LEDgirl, I know you've said that this light is for use during both the veg and flower cycles. Any thoughts of having additional models that target the veg or flower stage specifically by modifying the red/blue ratio? I can easily seeing moving to something like the 63w for vegging and the 126w for flowering but I personally would prefer to know that the red/blue ratio was tailored to that purpose.
I also noticed on your site that you offer an optional 30 degree bulb for the same price. What are the pro/cons?

I am ashamed, as a matter of fact - if there is a moderator looking at this I should be banned for my blasphemy.
I can't go round for round on all the techno mumbo jumbo because I am new to all of this and am jsut trying to get my sea legs right now but I feel like my investment in the lights definitely paid off in terms of extra medicine yielded the first time around vs others that I've seen in the same space with just the HID's. If it got me 4 extra ozs my first round then they paid for themselves already right? Not to mention the money saved on electricity and that the bulbs have a life of 100,000 hours. Plus, they saved my ass when my ballasts went (apparently hortilux aren't compatible with some digital ballasts.)
I can't wait to see how Ed's test goes but what do you make of this site claiming that he already has some of theirs in testing? http://www.maxxpower.us/led.htm Your's look like a better value from what I can see but just curious if he mentioned it to you.

To answer you first question, for people who want a primarily red light, you stick with the standard model. If you wanted a light with more blues, it's available on special request, where we change out the 3000k white, for 6500k.
The 30 degree lens is primarily for taller plants. Some people grow plants as tall as 4'-6', and they need a more intense beam to be able to penetrate to the base of your plant. The 60 degree is for plants up to 3' tall, with the light being as high as 12" from your canopy. The 60 degree obviously has more spread, which equals a larger coverage area at the same height above your plants, and the lateral spread allows it to hit leaves, that might normally be blocked by only downward directed light. Neither angle is wide enough though, as to where the light is not being aimed directly at your plants.

From their website, I can gather no information other than claims. There is no technical data listed to state what colors of light they use (red/blue, red/blue/orange, red/blue/white, 4band, 5band?), nor do they list any nm outputs (660nm, 630nm, 450nm). Lastly, they don't list their viewing angle, they don't list who makes their LED's (Bridgelux, Cree, etc..) and I didn't see a link to Ed's grow using their lights. I heard on another forum that Ed had done a previous LED grow using a UFO like design, and wasn't impressed by the results. I have no idea if it was using the product you linked to, or something else though...
It is my understanding that Ed will be posting results using our lights online himself. They will be uploaded to 2 or 3 different sites simultaneously, as he makes them available. So, if he's done a grow with their lights, my only question for that company is, where is it?

There are a lot of charts floating around, all showing varying curves of photosynthesis. While some are off more than others, it really depends on what plant you are speaking of. The plants we all grow, have points that I've listed plenty of times already, but a rose, or a grape, or a tomato may have a slightly different ratio that it needs, so graphs are only relative. They should not be taken as exacts. The only way to state exacts, is to list the nm's at which each plant absorbs it's peak amount of light. Then you tailor the light to your plant
Anyhow, no harm done with the avatar pic, I think it's kinda pretty myself, even if it's not entirely accurate

LED's do look like they will work fine. but what about OLED?....i've heard much about this technology coming out with the next gen of TV's.
IMO, i like being able to spend like 130$ on a 400 watt HPS light.
I like money in my pocket. So. Find a way to mass produce this stuff cheap, and everyone will be on board

lol thats pretty funnyI actually am very pro-LED... when it comes to making televisions that is! I have a Samsung LED HDTV and it is awesome in every way but I wouldn't want it in my grow room, that's for sure.

Thank you LEDgirl. I was going for that same effect.

To me the graph is visually appealing, sorry if I disappointed lol.
JR - I'm not supplying you with any more information. You are a Newer user on this forum, and your first PM to me was asking for all of the proprietary information behind my lights, which my competitor's have been working very hard to get. You continue to ask me for more technically detailed information than any other user, which sometimes borders again on proprietary info. From my standpoint, you either work for, or are gathering information to report back to, one of my competitors (likely ProSource). Because of the nature of your interactions with me since message one, you will no longer be receiving responses from me on this thread, or via PM. Sorry.
If you want a PAR graph of what a tomato absorbs, look it up! Google works just as EASY for you, as it does for me. I didn't study tomatoes, I just grew one with my light. I don't need a PAR graph to be able to see the results in front of my eyes. You need it why?

OLED's are becoming more and more efficient. I did a little reading into them recently, but to my understanding, they are not yet as efficient as the point-source 1W's that we use. They have been working on nanotechnology to improve the efficacy of OLED's, and they are expected to be the next big thing, but I'm guessing it will be another 3-5 years, before they'll be ready to compete. They are definitely very interesting though, and I'll be keeping an eye on them, as well as other bits of tech, throughout the upcoming years.

I just got a 46" LCD last year, and then the LED TV's came out! I haven't even seen one yet, but I've heard they are amazing. They seem to be quite a bit more expensive than LCD, which is expected as they are a newer technology, without the market share, but what's your take? Is the picture that much better? And what's the power consumption like on yours?I actually am very pro-LED... when it comes to making televisions that is! I have a Samsung LED HDTV and it is awesome in every way but I wouldn't want it in my grow room, that's for sure.

The LED's are strictly used as a backlight, before that manufacturers were using CFL as the backlight source for both laptops and TVs. LED's have a lot of advantages over CFL's in electronics (size, power usage, heat) but it took them quite awhile to get an LED with a nice even white spectrum. Earlier LED's had to much of a color tint that made them useless as a light source for television, monitors or laptops.
I used to work for a video game company that was heavily art focused and so we tested a lot of monitors for color accuracy and didn't really see a picture advantage with LED's, all the advantages were secondary (power, heat, longevity)

I thought OLED's were more like a sheet, where they could project a broad array of colors of light (maybe I misunderstood it in my limited reading). So if they are only used as a backlight then, what makes the picture? And if they're only a back light, then what's the big deal lol? (aside from lifespan...)
