STAY AWAY FROM LED's!!!!!

Thats cool no worries , i replaced all 5 x hps with Blackstar led panels in 2008 , all info is in thread , long story short was not enough coverage , light penatration and the quality of marketable bud just wasnt the same....

I am a survayour for an electrical company and part of my job is to survey factories and industrial unit for changing over from hps to led lighting we make some amazing savings for companys, an average led light conversion from a 400hps to a 125 led light cost around £500 a fitting from us and that is not including labour. These fittings are quality, the thing about LED lighting is that if you dont get the heat away from it, it rapidly deterates and goes dull within months, if you get a quality LED light fitting it will fins on it like a computer heat sink to get the heat disipated.

Sorry about any spelling.

Definitely. Light footprint would be the one area I could see these light companies reaching some major improvement. The Penetrator X series has the best looking coverage footprint out of the 3 I am testing, but it is still only 4x4 area. Personally if I was looking at a massive scaled grow I would likely not use LEDs, at least by themselves.. but for (4) 4x4 tents or something 2 or 3 times that size, I personally think LEDs would be my choice to yield the best quality product I could. The new 2011 lights are noticeably better than the older models, and I can say this from experience.

This is a different situation as the human eye and our plants use light in different ways lighting up factories etc would be for human use.

Ye your correct, i'm not talking about the spectrum of the light and the value of Kelvin's, i'm talking about the quality of the fitting and how the LED deteriates with heat. Most company that we compete with at work can fit LED lighting like us at a fraction of the cost but in 2 or 3 years time they will start to notices the odd led going out, the one's we fit are expensive units but they are more efficent at dispating heat and due to this we give a 10years warranty on every light fitting we install.

So when you buy a LED fitting make sure there is a path for the heat to escape, fan or heat sinks normally.

Its very nice but not the discussion topic , you are growing stealthy small plants in a box or closet , we already know that led can get results this way your arguing with Drfever who has so far managed to post lovely pictures also but not made any valid points what so ever !!

I am not convinced enough YET to give up my HID's and cant afford to do so until I have the proof that LED's would generate the same yield in the same space and still be cost effective but.....

I do love technology and if I wanted to try LED's on 1 plant is there anything I could pick up for around $100 to try it out?

I feel like we all came to the same conclusion. Until we get more watts, per diode, LED's simply won't provide the depth of coverage (aka penetration) for commercial style grows. So we all agreed on that and this thread died for a few days....then someone comes along and says "I THINK MY LEDS OUT PERFORM A 600W HPS, THEYRE AWESOME-O" and the thread starts allllll over again....

In conclusion : LED's are very effective when put in the proper environment. Any grow utilizing tall plant that need to bud all the way down to the rockwool almost...simply is NOT the environment for a panel utilizing 3w diode. Regardless of the lens angle.

Now everyone agree with me and we will all be content until next week. When someone says
LED>HPS or HPS>LED again. Then we can start from the beginning......again.

Intriguing, but not available in enough wavelengths or in smaller than 120 degree lenses to make a solid performing panel....that is, unless a 6w @ 120+ degree lenses can outperform a 3w @ 60 or 90 degrees...i dont know the answer to that but im definitely interested in finding out, but then we'd still be missing some key wavelengths which I guess could be added using a different maker's diodes.

Dude chill out...Collective gardener is one of the nicest most helpful people I have seen here in a long time...instead of engaging him in a mental battle for which you are so obnoxiously ill-equipped in comparison by a long shot, why don't you engage him with an inquisitive mine and get that real knowledge one can only get from actually running a 20000 watt grow? Doesn't that seem much more of a win to you than this useless challenge which you have a snowball's chance in hell of winning? Just saying....

Energy cannot be created or destroyed, it can only change form. Meaning that you will still have to use 1000 watts of leds, to equal the light output of a 1000 watt hps and i also seriously doubt that a 1000watts of LEDs are going to be anywhere near the canopy penetration of that of an HPS. So what is the point? To me these bullshit fixtures seem like light brites repurposed. With these consumer grade made in china fixtures middle men hock to people in high times you are going to get some whispy disappointing buds because they don't provide adequate light, simple as that. I have personally known three people to try these and none of them still use these fixtures because they aren't adequate in light output.

Personally I think that leds are infact great for practical purposes like lighting in the home, but growing ganj inside under lights is not practical and we aren't able to cut corners on the light we're providing, light is number one priority for my garden.

Another thing with LEDs is that everyone is arguing "oh man the wavelengths of light are so much more dialed in for photosynthesis". One big hole in the LED balloon is that many led manufacturers simply dip a translucent led into molten plastic to "color" the output of the led. Kind of like how lighting rigs utilize theatrical jellies to slide over the lights to make them blue or red or yellow or whatever mix of colors they want.

Sorry about starting shit,, my apologies, but I am sick of hearing the back and forth argument that people are going to get the same yields of a 1000 or 600 using a 90watt led.
