Well you're wrong. I'm someone who got into LED, found some good ones, and helps others interested in LED or those who it would work well for (as I've gotten through all the crap LED tech and grows that naysayers haven't, I know the bullshit LED from the not). If you read 800 of my posts you'd know I talk about several differen't LED companies, none of which I work for*i looked at bout 800 of your posts im pretty sure your selling lights
If you can give me examples of crappy LED flowered grows, I can show you they were done with crappy LEDs. And I can show you a good grow with a good LED. That would be much better than what you've been doing, you don't need to give examples necessarily, you just need to do something different in this thread than what you've been doing.do i need to give examples?
What's with the asterisk?Well you're wrong.

Just to point out that I don't work for any one them. Thought it would make it stand out a little more. Oh I guess i forgot to say it would be extra unlikely for someone to work for more than 1 LED company anyway.What's with the asterisk?
so by what you've said, instead of buying the $1200 stealthgrow 300w LED, i'm still gonna need 3 of those to match my HPS yields? so my 1000w light which i could've found on craigslist for around $100-$150, and costs around $30 extra per month on my bill ($360/yr or around $2k in 5 yrs, + $500 for replacement bulbs), and you think it would be a good idea to spend nearly twice that in the same amount of time, for unreliable fixtures? perhaps if you're growing in a REALLY, REALLY high risk place i may consider it, simply due to not making noise and no heat signature. even at that doubling my investment is a hefty pricetag to put on being discreet.Nobody I know of sells LED panels that use more than 600w (and the 600s are usually 1w diodes). I won't argue that LEDs can penetrate better than a 1000w HPS, but a good LED will flower at 1 foot away and through at least 3 feet of green (so yeah not as suited to growing trees as 1000w HID, but they are much better suited for things like SCROG considering their features). For a 4x8 I'd except to spend $2000-3000 to replace that 2000 HPS with 1000w LED at about $2-3 per watt (2 is the good low end, 3 is the most reasonable high end), which is a shit load more than for someone to set up that space for 2000w HID, but you will have only 10% as much heat to deal with (biggest pro when it comes to LED is that it can grow as well as HPS but with >25% as much heat watt for watt)
I agree that no single LED can touch a single 1000w HPS, but 1000w of the good LED panels will grow more/better than 1000w of HPS (the more panels its split between the better). I agree for large legal commercial grows HID is still most viable (most reliable, cheaper, pays itself off faster, and if the DEA comes you won't lose as much investment), but for anyone growing in their house, a room, shed, I think LED is worth it now. HID and LED each have enough of their own pros and cons
PS: I agree to cover 2000 sq feet with the best LEDs it would cost 90k if you bought whole panels WITHOUT bulk discounts and didn't build your own to any degree. But for people growing in say a 4x4 tent that works out to only costing them $1000-2000 depending on what brand and how many watts, yes this is much more expensive than an HID set up for that space, but one must consider all the pros and LED has over HID and realize for many its a viable option. I think its most viable though for people living in locations where it is just too hot outside to run HID set ups plus air conditioning
In no particular order, blackstar, isis, magnum, GLH, advanced LED 3w, LG-LED solutions, hydroponicshut pro-grow, apache tech, blackdog, are companies I keep on my listwent ahead and ditched two 400w hps lights cause they took up way to much electricty and I don't have adequet heat ventilation in my basement closet. I still have a shit ton of CFLS (105, and 65w flowering and veg spectrum). Looking to go all LED + CFL as side suppliment light. As of right now I have a 90w UFO from LED Wholesalers 2 diode quad band, a Hydo Hut 180w (3w chipset) pro grow, a 50w (1w diode) all blue veg LED (origin unkown - ebay). I'm going to order one more to make it complete. I only grow four autoflowering plants at a time as four is a misdemeanor, five a felony in my neck of the woods. So the question for the LED users - what to buy? I'm considering a blackstar 180, maybe a 240 if I can talk 'em down in the price a little bit. I already have a Hydro Hut and want to buy another from a reputable company, looking for at least 180w output, don't want to spend any more than $270 max. Cheers!
It should be cheaper if you know who to call/buy from as far as parts go (factories, warehouses, US/China). But it would seem to me that the people having much success building their own are the people who end up starting their own online LED business (some which are crappy ebay ones, others that are fairly successful with their own website and on the list i mentioned, or seven sponsors for some websites like this one). They are generally reliable, the only problem I've seen people have is losing power to a bunch of LEDs at one. Sometimes its a bad power supply, other times an LED crapped out and took out the power lines for other LEDs so to speak (but some companies avoid that issue ). I've read of people fixing their units with an new power supply, I don't think they can really break so bad you can't fix em. But as far as replacing single LEDs, that I don't know. The company I bought from used the tech to keep more than 1 LED from going at a time, and they said that also makes it easier to switch out dead LEDs. The only company I've seen issues with units crapping out in month or two is Kessil, but I think they that was a factory error thing they fixed.So what does it cost to build your own panel. Can this make it affordable? I would like to stay up on this emerging technology and learn more about it. Are commercials panel really unreliable? what goes out, can they be be fixed?
in a home-grow. in a 5'x5' area, if i had a single 1000w lamp in let's say a common flood and drain system.In no particular order, blackstar, isis, magnum, GLH, advanced LED 3w, LG-LED solutions, hydroponicshut pro-grow, apache tech, blackdog, are companies I keep on my list
RRLBT420 what is the system and size of your grow you are thinking of when you say that?
i hear the power supplies are a common failure as well though as they're one of the parts manufacturer's cheap out onIt should be cheaper if you know who to call/buy from as far as parts go (factories, warehouses, US/China).

If I'm not mistaken I think the issues with stuff dieing or failing quick was with round LED panels from not so great companies anyway. But to be fair, nobody has really had the chance to run an LED for 50,000 hours yet, the better panels with 2/3w diodes have only been around a year or two, so we really can't know how long they will last. And any LED panel that has been around long enough to run near that 50,000/5 year was made withold LED tech poor for growing, and who knows how reliable the parts were. Now companies seem to care, and the panels can actually grow. It is yet to be seen if the majority of panels will last 3-5 years. I'm hoping mine does, I at least won't have to worry about losing more than 1 LED at a time, but I suppose there is a chance the power supplies or cord socket could go (5 year warranty)
Yeah I guess you gotta hope they cared enough to go for a quality power supply as that seems to be the only thing going wrong besides LEDs just dieing out.in a home-grow. in a 5'x5' area, if i had a single 1000w lamp in let's say a common flood and drain system.
in a few more years when they're more cost effective and reliable, they'll be far more practical. they are unquestionably more efficient watt-for-watt, but they still need better penetration and a larger footprint to impress me. then they need to cut the price in half or betterYeah I guess you gotta hope they cared enough to go for a quality power supply as that seems to be the only thing going wrong besides LEDs just dieing out.
Hmm for a 5x5 I'd try and aim for 30w or so of LED per square foot (from the top LED companies), and the cheapest I'd go with is $2 per watt and the high end $3. So it could cost anywhere from $1300 -$3000 depending on how much power and from what company and if you get any discounts such as with a bulk order (not sure how much that requires). Since it would be for a 1000w HPS though, I'd try and split that across several panels, perhaps 4. (If it was say a 400 or 600 HPS you could get away with just 1 panel, but no 1 LED panel can replace a single 1000w HPS because they don't make LED panels large enough for that). Basically for anything less than a 1000w HID, I'd replace it with about half the wattage from a good LED company (with other companies you might need 75% as many watts)
*I'm just not sure as much how to replace a 1000w HPS with LED because its footprint is just so much bigger. LEDs are usually crammed into a panel and no single LED panel can handle more than 4x4 if you ask me (and any one that could would probably cost >$1300). Replacing a smaller HID like an 800 or 600 or 400 is easy because single LED panels can compete with those .
*If we're talking 1w LEDs or 2w LEDs then all that stuff I've said is bunk and you would need a lot more power (because CRAPPY led panels suck). Not to say all 1w or 2w panels suck, there are some good ones, but they do still suffer from poor penetration so most grows done with them are not that impressive.
* I realize there are panels using diodes that are greater than 1/2/3w, but I can't help when it comes to those (i just don't know or have seen anything done with them)
Yeah I hope it will be a lot cheaper soon. 3w with <100 degree angles seem to get good penetration (better than my 400w at least), I wouldn't start to worry unless a plant was getting over 3ft tall. They made the jump from 1w diodes to 2w, and I think you could say 2011 is the year that 3w came to place. Perhaps next year it will be 5w diodes and they will really put the doubt out of peoples minds?in a few more years when they're more cost effective and reliable, they'll be far more practical. they are unquestionably more efficient watt-for-watt, but they still need better penetration and a larger footprint to impress me. then they need to cut the price in half or better
true, but the biggest issue i've seen with the higher wattage diodes is shortened lifespan, especially with the cheaper units as they tend to overdrive the diodes. again i think they will have a future, but i think they really have to figure out how to make them far less expensive, and more reliable. in 1900 people probably never thought that nearly everybody would own a car someday, but Henry Ford found a way to make them affordable when he invented the assembly line. LED will need somebody like him, who really cares about progressing the industry and who's really motivated to make the necessary improvements to make them practical in most grow rooms.Yeah I hope it will be a lot cheaper soon. 3w with <100 degree angles seem to get good penetration (better than my 400w at least), I wouldn't start to worry unless a plant was getting over 3ft tall.

I'm sure I'll end up getting another big LED unit in a 2-3 years when the tech puts the present to shame
one of the biggest problem they need to solve before led will ever be applied to things like stadium lighting is how fast the light intensity degrades over distance. part of the reason hid lighting is popular for that task is it's low degradation over distance. if you've ever put one of those led replacement bulbs in your closet, you'll notice that it's very bright immediately around the bulb, some so bright you can't look directly at the bulb, but you'll be lucky if you're able to see the floor. granted these aren't the same power as you'd expect to see in stadium lights, but you get the ideaI've seen high output color mixing LED's used in mission critical applications for years. Like HID, it will likely be a product developed for industrial applications. an LED street light or stadium lamp that is repurposed. We definately need the benefits of scale to bring this to the masses. Probably be GE, Sylvania or Philips that come up with the right combination of price, performance and reliability.
