Led Users Unite!

And this other guy has this listed on craigslist

"I have for sale a custom made Tri Band Led Grow Light. This light contains high end components. Contains CREE and BridgeLux LEDs and a Meanwell LED Driver. This light contains 660nm red 630nm orange and 460nm blue LEDs. This light is as powerful as a 250w HPS I used this light 2 months with GREAT RESULTS it vegged my seedlings and flowered my plants with AMAZING results. This is high end for the serious grower. You will be AMAZED how powerful this light is only drawing 50w. If interested send email I will respond ASAP. Thank You."



I'm sure I've bought less for over $125

That first one looks ok, I think that was the only LED unit at the indoor garden store I went to a couple weeks back and they wanted $500 . I don't see any reason not to like it, but since there may not be any proven journals and the unit is used you might want to get something else (besides for 500 you could get a 180w GLH). As for that other one, I wouldn't buy used LED ever as you have no idea how many hours it was run and you should probably not get it for the same reason they are selling it. Plus you will want a good warranty because most LED units are built in such a way that so if 1 LED dies you might lose half or more (3-4 companies have gotten around that). If the 2nd one has lens angles of 120 it might be worth it for a PC grow box?

On the second one he give's a 5 year warranty and only deals locally where we both live. F it, I'm giving it a shot!

The Blackstar 240 panel for instance. I have been looking, but people arent giving answers relevant to my situation. The idea of a board is to share info and discuss topics, yet when people ask questions they are told to search more. I wouldnt be asking if a search had revealed anything.

i use black stars and i get them as close as 6 in flowering, girls love it... 8-10 in veg.....no need for any further...

some guy was talking 22inches away somewhere on this forum when i was reading and that's just stupid, get them close enough that they don't stress the plant yet far enough for optimum coverage. your plant will tell you if your fucking it up...

The guys who sold me the ISIS-FX1 told me to run it at 6" from seedling all the way through. The lens angle has a lot to do with it as well.

can u use leds as a suplemental source of light just as the cfl's help the no dual spec hps ?

could they replace one out of two hps so to lower the temps ? i know that "u can" will the results be comperable ?

im interested in many panels easilly adjusted rather one big standing on top , what make or type should i look for ?

"You are using 1w LEDs which despite what their page says, are the worst you could have (the better being 2w LEDs the best are 3w although I hear some are starting to make 5w). 1w LEDs also don't run at 1w they run at .5 to .7 (so are you sure there are 428-600 LEDs on that panel?). On top o that they admit that they don't hit the exact spectrum they know to be best, this is because those are not available in 1w LEDs I think (or they are just not trying to sell the best available stuff). Obviously they still grow, and you will still do pretty good. For what you may have thought to be 750w of LED is more like 450-500w of low end/quality LED light (but still way better than a lot of the shit sold on ebay)"


uhhh.. what? you are mistaken there buddy. A 1W LED is the most effiecient diode out today, not the worst. And an expensive 1W will most definetly be available in the peak bands for plant growth, but not only are they very rare, but finding a "peak" band diode is going to be tuff.
But if, like you said, you have 1W diodes only drawing .5 - .7 you do not have the 10mm HI diodes. You got jipped on your light prolly have the 5mm ones

3W diodes can be good, but not as great as a 1w 10mm is what I read. You are paying for diode that isn't being powered fully. better to have 1W diode being powered up as much as it can. but hey, some people have more money than they know what to do with, so spend away

and 2w don't come in teh "peak" PAR bands for photosynthesis, i would never buy a light with 2W diodes, or a light with 12 spectrums. lol it is common knoweledge these days that if a peak photosynthetic band is hit, the other, much much less effiecient spectrums are a waste. i would never buy offpeak white, green, yellow, etc. diodes... big fat waste of money IMO

Green Dave- thanks for the come back- appreciated. I looked on the website, but like with most of them ya can't tell much what the ingredient list is.

...and this was fine until I turned on the red spectrum. Couple days later leaves showed stress (leaf tear and margin curling up). Got it at 10" now.

Ok, since there are 365 pages to this thread, and I dont have all day to browse through them all, I'm just going to come straight out and ask. This thread does not seem to have much information or feedback(from the 20 or so pages I have browsed through) from actual LED growers. I was wondering if there is anyone here with FIRST HAND experience using LEDs. I'm interested to know, what you grew, the type/company who makes the LED, wattage/lumens, how many plants, yield, if used for both flower/veg, etc.

Basically I'm in the market for an LED right now and I've come across a couple different brands, but I'm unsure about the quality of the lights since a lot of these companies seem to stretch the truth about their products. I'm looking for the best quality 90/120w LED, any suggestions, or even a list of companies that make them would be greatly appreciated!

i also want to get some leds...it seems hard to get more than 2 people to agree on the best light here.. from what i have gathered in this thread..only buy an american made led and it should have a warranty (2 years at the least)

The blackstar '240w' (actually uses more like 133-140w) is a pretty good light and you could get one for $250-300, that is the cheapest most proven unit for less than $300 with 3w diodes (its also put together in the US apparently). The most proven units for more than $300 with 3w diodes are GLH/Spectra LEDs from growledhydro (all come with a 5 year warranty and 4 month return policy), which is what I use along with Irishboy (look him up on this site, a bunch of sweet LED grows) and some others who migrated from 420mag.

GLH is also one of 3-4 LED companies that build their lights in such a way that only 1 LED can die at a time (instead of losing half like you might with a 'UFO'). Blackstar doesn't do this yet to my knowledge, and GLH is the only company I can find that does that with all 3w diodes

ISIS/Magnum and GLH are the best with proven journals from several users. Blackstar is the cheapest with proven journals. These lights are supposed to last 10 years so get a good warranty

thanks@ colorado love

Ive only used leds from one company and I'd recommend them to anyone. I did a lot of research before purchasing, but I don't have any regrets. I'm still on my first grow with them, but so far the results are just as good if not better than the hid lights I used un the past.

After all my research, these are the companies I decided were putting out good lights (note...i didn't look at every light or company out there so I'm sure theres some great lights I didn't include on the list):

Advanced LED - 3w extreme flower models (this is where I got mine)
GrowLedHydro - spectras (lots of growers happily using these out there)
Isis or magnums - cant remember the seller but they supposedly make good grow lights too
Black Dog led - im really impressed with their lights, probably the other company id test out after advanced led
Black stars - inexpensive but people are happy with them
Supernovas from hidhut - not many growers posting journals with these but the ones out there are impressive
StealthGrow.com - they have some good models available too that people are successful with

If you were to pick up any of the lights from these companies, i feel like you'll be happy with your purchase. Hope this helps!

if your going to start using PAR photosynthetically active radiation why not use PUR photosynthetically usable radiation wouldn't you get a better idea of how well the units preforming?

I personaly agree with meharmon we all cant afford the equipment for reading PAR ect so lumens/lux is an acceptable beginning point.

Im no expert but could someone explain to me why we use PAR instead of PUR?

Click to expand...

You're definitely right, if we had access to the PUR ratings we would be much better off and all of this would be easy to compare light sources. I assume it would take some fancy equipment to get this reading from HPS, etc., but if the grow light LEDs are putting out light in specifically tailored wavelengths, then all of it should be PUR, with the exception of the white diodes (since a good amount of their output is a hump in green/yellow range). PAR is a bit misleading because it contains a large swath of "useless" light of course, so even if you throw a PAR meter under a HPS and LED with equal PAR numbers, the LED would have much more PUR assuming it was designed like the models we all use.

Thank you bro +rep this is probably the most informing info I've gotten from this whole thread I would love to sit here and read all these pages but unfortunately running this comps 650watt power supply all day puts a damper on my electric bill I come on RIU now strictly to update my threads and god forbid research any problems i'm having my lifestyle has made me the type of get the point person I am.

[email protected] i were going to buy leds but not going to use them until fall.. is the tech advancing so quick that i should wait until september? or 4 months from now there will be little change?

Well, from what ive been seeing is that the progress is sort of slowing down, although some companies are just starting to come out with 5w models but I think it's safe to say those ones are still a couple years away from being priced similarly to the top of the line 3w models being sold today. I think you'll be fine waiting to purchase in the fall, I don't expect the 5w models to take over for a few years and definitely not by this fall; id be surprised if that happens so soon. If anything changes from now til fall, it will likely be price drops (how much if any I don't know) but probably worth waiting a few months just incase if not planning on using right away
