Thanks for the vote of confidence dude!!! It was your posts that made me look at GLH... thanks for the push! I know there has been quite a bit of debate about penetration of light and lollipop plants properly to get 1W diodes to grow great. and yes, it's true if you properly train your plants 1W diodes grow them great. but with penetration of the GLH in these photos, who needs to train plants!! I am very impressed with the penetration!!




this is what I like to see visuals they say a picture is worth a 1000 words and I can truly see the efficiency of these lights it really brings hope to a more natural grow for the plant rather then training the plant to the efficiency of the light source

Whats wrong with Blackstar? Their '240w' seems like a pretty good option for a lot of people who can't afford more than $250-300 for an LED

How did you come up with this list, just curious why you have these opinions because I see people happily growing with some of the lights on stay away and unproven sections of your list, not to mention other lights out there that are producing well

There is a huge difference in radiant output power (light) between a true 1W power die and the collection of little chip dies that are placed on a metal core PCB and these LED sellers are claiming as '3W LED's'. They are not '3W LED's', thay are maybe '3W modules' or '3W arrays', but definitely NOT '3W LED's'- you can't take a bunch of inefficient chips, bunch them together, and have them get any more efficient.

While it is true that there are 'some' highly efficient, true 3W dies being produced by a few companies, these are terrifically expensive and not available in the wavelengths necessary to satisfy the photosynthetic demand of the plant.
This talk about this 3W die and that 3W die- well, not exactly in the real world.
This guy is using Epistar dies in his product- he has said as much in other forums (i.e. Setting Sun on 420). These Epistar dies come in 40 and 45 mil^2 sizes, depending on which process die you are ordering. Yes, that's right, the approx. 1mm^2, 1W package that I have been referring to. And what power level is he apparently running them at? 1W (unless the picture/ LED arrangement on his web site is not correct for the new model). These are true, 1W power dies. The marketing and sales people have stuck everybody with a virtually useless metric by which to judge a grow light with so you will buy it over the Internet- 3W this and 5W that- BS.

And yes, you can over-drive these Epistar dies (more current, or more Watts, or however you want to describe this) beyond 1W, to the degree which the fixture cooling system will allow vs. what you consider the acceptable service lifetime of the fixture to be- but again, this becomes very tricky- it comes at the expense of LED lifetime and reliability.
This information is for the new 2011 Spectra LED™ models:

First of all a big thank you to both astro and GLH for contributing to this thread and setting the record straight! I think we are uncovering another important piece of the LED BS marketing machine.

astroastro, If I understand correctly, then the GLH units use TRUE 1W dies BUT hooked up to a 3W LED CHIP. Is this what allows them to be overdriven to 1.5-2.0W with relative safety? I guess other manufacturers have them hooked up to 1W chips instead or do they have LESS than 1W diodes hooked up to 1W chips?

If this is correct, then what is the relationship and resulting difference between a 1 W die on a 3W chip and other "lesser" combinations?
 
Hey guys just thought id stop by and let you know whats up with my LED panels to clear up any confusion. I know the website needs to be updated and I do have a new website under construction its just taking forever. Anyway here you guys go.

Hi mate, I'm very interested in a 500w panel, and was thinking of this one:

http://hydroponicshut.com/Pro-Grow-550-Watt-LED-Grow-Light.html

Which is much cheaper than what you sell, but I'm a rookie and I'm sure there's a huge difference between this and yours. I have a 180w version from those guys and have (to my mind) gotten good results from it, but I'm intrigued as to the benefits of yours. Any chance you could provide a "this is why mine is better" comparison with the above?

it only uses 385-420w, it doesn't have as many spectrums, warranty is 3 years instead of 5, and it doesn't say anything about what lens angles they use. They actually work out to be about the same price $1.9-2 per watt. The only reason I would get that one instead of the GLH 500 is that you can switch some of the lights off, but to me that isn't very important. But I would also recommend going with as many smaller watt panels as you can, I'd only get the 500w if you plan on using light movers or if its grow space will only have an area of 3x3 or less (when there wouldn't be much wiggle room for multiple panels). Don't get more than 50w of LED per square foot, try to aim for 30-40 if you want to save power but grow as well as 50w of HID. I got the 1st 2011 edition 395w GLH (same as 500w except avg wattage of diodes is 1.52 something instead of 1.9 something) in a 2.5 x 2.5 space and its definitely over kill at 62w per sq foot!

Thanks for the info. The angle is 90 degrees. Is there a need for greater variety of spectra? I remember hearing that several fewer was "enough", then when more were added to the mix that was considered all "usable" light, but now the yardstick seems to keep shifting.

I have a 2m x 1.65m x 65cm tent, and will look to grow maybe 6 full-size plants at a time, so perhaps it is indeed worth having multiple smaller panels so I can have greater accuracy of light distribution. Good thinking, Batman! :-D

Your going to need more lighting than a single 500w panel in a 6x5ft tent. Send me a e-mail if your interested in my products [email protected]

Their false advertising and shady marketing.

Claiming they use CREE diodes? When they come from China?
Advertising more wattage than the led puts out?

They are not bad, but the performance from 2 Blackstars you can get from 1 2011 GLH at the same price.

GLH represents honesty which is the hardest thing to come by in the LED grow market.

oceangreen, are you on GLH's payroll or something? Take it easy with the sales pitch and show pics of plants grown under GLH to convince people. I think we all know they work well by now, but always want to see more results.

EDIT: Took a look at your posts hyping up GLH all over and a week ago you didn't know what panel to buy, so I guess you never grew with LEDs...

How did you come up with this list, just curious why you have these opinions because I see people happily growing with some of the lights on stay away and unproven sections of your list, not to mention other lights out there that are producing well
Well, I am only listing with products, that I have dealt with.

The good list:

GLH: Don't need to say much about GLH. Track record speaks for it self. Mike is a true business man and keeps it honest. He answers emails. I want everyone to send an email to all LED manufacturers, Mike will be the first to reply, I promise.
He care's about making a good LED which is what we are all after. I think he has done a fantastic job for a business in its first years.
Lets be honest. MH and HPS will be replaced by LEDs. I mean these things will get lighter, smaller, brighter, more efficient in the next decade. You will be able to fit all your Lights in a box in your trunk thanks to LED.

LUMIGROW:

I tested the ES330 and its a solid LED. It is quite expensive, but it is the ONLY american made LED, referring to the diodes. I am sure some parts come from China, like the housing. It has a good design and obviously a lot of money went in to making this solid LED.The light may seem out of spec as they have not changed the specifications or design for a while but it is true to specifications.

Jumbo LED, is also Chinese made. I have not personally tested this LED, however I have seen them in action/application and the results were on par with the Lumigrow es330. The only thing that i did not like was the UFO design. Its obvious that panel LEDs provide a better housing for higher powered units because of light distribution, even though the Panel LED will emit a circular distribution.


The bad list:

Sunshine Systems
I started with 2 sunshine system UFO 90w with 2 125 CFL's. I liked the UFO for veg, it did its job. I decided to test the power output and take the thing apart. I saw a light system than any high schooler could assemble. I don't want to go into technicality, but the "90" watt UFO was producing close to 58 true watts. I will give sunshine credit for great marketing and a very nice design, but thats it. They use 1w diodes from China and it's not Epistar. Sunshine also commercialized their product and spent more money on design and image. Even the box it comes with is pretty. They don't spend money on performance, which us serious guys want.

HGL:
Where can I start with this company other than the track record of the owner. A customer on here was shafted and disrespected after spending 6000 dollars with HGL. The Owner did the most dis honerable act to any grower, calling the cops, after a small dispute. Who in their right might would do that. Further investigation results in previous scam business' by the owner resulting in a change of identity and gender. Many users claim their LEDs are junk. The list goes on. What bothers me the most about it, is the fact HGL encroaches GLH. It does so by having a similar name and place of operation. I am sure many customers have confused the 2 companies, when in fact GLH is the best thing out there right now.

Blackstar:
Claims to use CREE diodes. Thats a straight out lie. They don't even use Epistar from China.
Their LEDs advertise a higher watt output than it produces. However, as we know now, wattage is not the only thing that makes an LED.
Blackstar uses the cheapest best material to make their LEDS. They are however an ok deal $/watt. Again, more wattage does not mean a better LED.

I have heard good things about Blackdog and was recently introduced to Future LED. However I cannot comment because I have not had personal exposure to these 2 products although I know they will perform well.


I hope I cleared things up and everyone has their own opinions, I understand I did not provide hard evidence to back up my statements. I will however do a Direct Test between all these lights, and will provide LED GUTS in a separate thread soon.

Thanks,

Ocean

you misused GLH for HGL in the HGL section once ;)

cool! I'm interested to see what these panels looks like on the inside, as I certainly don't want to risk screwing up mine by doing it myself ;)

I have NO association with GLH. I can put my life on it. I love LEDs and GLH are the best right now. So I support them, largely.

I was just testing out what users on here have dealt with and wanted to know everyone's opinion. I have done a Sunshine, Lumigrow, and Currently in process with GLH's

Do you have any pics of all these LED grows you've done? 14 posts, just signed up during the past 13 days, and became the LED spokesperson already?

Haha, I like it, good one. I'm no Spokesman. I will put up a journal within the next few days, detailed. As for now, Ill stop hyping anything up, so people don't get the wrong idea. I'm usually on grasscity, so I am new here.


Thanks Man
