THE FUTURE IN LEDS's!!!

I am not disagreeing with that. Lumens are important only when everything is set up correctly. I do agree that light with a higher par rating will be absorbed more efficiently by the plant. I am not specific enough. I sound like a liar. Basically i mean that if you have the perfect lighting spectrum from 2 different lighting types, then taking a lumen reading and finding out which puts out more lumens per watt. That light is the best for the plant. The measurement is accurate for these purposes as long as you are comparing the same par kelvin etc. Besides i think your supposed to be watching my LR2 grow. lol

That's better. It is easy to interchange lumens and raw intensity(SOOO many companies/people do it). I've done it myself, many times... carelessly.

Yes full spectrum does help, there are all kinds of flourphores in plants that only use certain wavelengths to do certain processes. Cryptochrome and phytochrome to name a few.

Oh yeah and teatree, yeah ill def agree, yellow-green i was thinking yellow AND green. And yeah i love my hortilux bulbs. They really concentrate on a full spectrum.
 
I know. I have a 1500 watt something over my pool thats probably 1000000000000 lumens of the ugliest light you have ever seen. It probably can't grow a single chia pet.
 
Another funny thing that most don't know is that t8 flouros are some of the worlds most efficient lighting. They can achieve 100 lumens per watt with a par rating of at least 93. Seen them at canadian tire for fifty bucks for the fixture and 2 bulbs. Only problem is that light is to spread out so penatration is like asian sex.
 
Those star-wars lightsaber guys love those LUXEON leds.

540 lumes outta a 7 dolla led running off a AA battery.. Hmmm, I would need ALOT of those I bet.

http://www.luxeonstar.com/luxeon-rebel-star-c-29.php
Up to 540 lumens at 700mA!

Standard Star Base - Same footprint as standard Luxeon Stars. Use standard hand soldering tools

Single & Tri-LED - Available with a single or three pre-mounted Rebel LEDs

Ultra Thin - Just over 1/8" (3.9mm) thick overall

http://www.luxeonstar.com/fluorescent-tube-leds-c-15.php

leds in tubes.....i wonder how many lumes....

That lil link OP posted "maximum yield" lol kinda funny name for a mag....but anyways:

Depending on the situation, brighter light with an obscure spectrum may not prove as proficient as weaker light with a balanced plant specific growth spectrum.”

I thought the situation was we are growing plants?

I never knew it, but is that saying the spectrum of light is more powerful than the actual watts used? Hmmmmm, i somehow doubt that. cause the sun has a spectrum I bet hahaha.....and 4000 gajujillion jiggawatts.

All I know is this guys is THE shit on youtube when it comes to LEDS. IF ANYTHING THIS GUYS KNOWS ABOUT CIRCUITS AND HE WILL BUILD YOU ONE CUSTOM.

You can truly see how bright that Luxeon is later in the youtube movie.
 
I'd love to see that.Please check and see whether or not the company that makes those LED's is in any way advertising on that site, or in that magazine.

Everyone just needs to go out and get the HIGH TIMES growers/beg guide 2009. Its avaliable all year long. In the end it talks about lighting and what cannabis needs. It then goes on to do a side by side comparison. I will go find the mag if peep want details. Anyhow the 99w LEDS outperformed a 400w metal halide by 10%. Then it lost to the 400w hps by less than 15%. It goes on to talk about how they designers had to use the wrong wavelength of blue and red because of the costs. The wavelength they used was twice as cheap. They said that as prices go down, it shouldnt be unexpected to so LED outperform a HPS. Again per watt the LEDS already bet a HPS ANYDAY. Its just cost. Go back in time 30-40 years, and ask how much it would have been to get a HPS.

Looking forward to it.

If you can give a link, that would be cool, or, if it's an actual magazine you're reading, the issue date and number and the name of the article,because I'd like to read about it.:bigjoint:
Also, yes, this is a hobby...and it's expensive enough with HID lights, ventilation, nutes, etc....unlike other hobbies where you do something without a lot to show for it,like beadwork, painting,etc(and I'm not ragging on these hobbies,just saying paintings don't have any THC),the purpose of this hobby is to get the best quality you possibly can, each and every time.Since it makes much more sense to me, right now, at least,to go with a setup that has been proven to grow the quality I'm looking for,without putting me in the poorhouse(remember, most of us are growing because we don't like the expense of buying)then right now, my choice is to stick with tried and true.If I had a lot of extra money to blow, I'd experiment, too.:peace:
lampshade said:
Ok i just re-read the artical. Soooo high times says that the LEDs outperformed the MH by 12%. And that in underperformed the HPS by 5%. Also the LEDS took a week longer to finish and experienced stretching. This is b/c they were not using the right spectrum of blue leds, due to cost. People are still working on the technology to make this product cheaper, but there has to be a market for it to get started. So in my opinion, if you want an experiment, then go for it. To alot of this growing is a hobby, not about money.

I know, my point is that hobbys cost money. Its what its worth to you. Beauty is in the eye of the beholder. And some of us are fascinated by new technology.
Golf will crush your pocket, Alot of coin collectors spend thousands on a piece of metal. Some people like to modify cars. Now thats expensive.

Anyhow, im reading the mag. I also just wrote the editor so hopefully in a couple of days we will have somemore info. The mag is the 2009 Master Grower's Guide. Its avaliable year long, and its $6.99. It should be sold wherever HT is sold.

Oh also, they used the UFO, and yes they do advertise it. We will never know if the were biased in there testing or not.

Also if they skipped the veg im assuming led would perform better. B/c the UFO is known for stretch. They said they fixed it, but who knows.

That was one of the questions i asked.
 
Hm.Do they also advertise the same brand of HID's that they used in their experiment?

I agree, thats why i asked all the questions i could, without being invasive. If they dont respond i will really wonder.
 
Actually snowman looked up the real luxeon. Good for you. You gave a realistic lumen number also. Luxeon leds are insane but so is the price. For lumen and par output per watt nothing can top led. But for 10% the price hps is 99% as good. Except for the heat. My led fixture is the brightest light i have ever seen. But it was a ripoff. I could have used slightly more watts in metal halide and got the same output and saved the money. But at least i have it now. it uses 400 luxeon and cree 1 watt leds.
 
Well the one I posted wasnt "the real" Luxeon, just a version/type of one. A type of luxeon, at different specs and such, such as mah rating, watts, output, price. And that lume spec is for the white one. The clearest one. Take a blue one now and the rating is slashed. Im sure there are more versions Luxs and other names for these leds. Not feasable to eclipse a MH or HPS in price, and performance, and most of all, reliability.

I swear purple color tint LED is very new, like within the last 3 years new, that is bright that is. These saber guys were searching high and low for a bright purple led they could wire in sequence for thier LIGHTASABERSZZ. Theres another guy in china, i forget his name on youtube, but he made the leds 3x brighter with his own kit and it seems he not giving out the secret.
 
3 and 5 watt led's penetrate very well and now are considered a viable option or alternative to HID. A 150 watt led system with 3 watt leds will yield far better results than 250 watt hps. Make sure you get a full spectrum with white lights included in the array. The 90x1 watt ufo's dont penetrate well. An all blue led array will completely destroy a MH per watt.
 
I'm a little irked to hear you talking LED-Lumens. Lumens are for Humans. They are heavily weighted in green, something an LED light puts out little to no photons of and something we see mostly in (sorry about the dangling prepositions).

That's why no LED ad that isn't just marketing hype will mention Lumens (except to debunk the misconception that it means anything when discussing LED output. Photon flux density is what we're after. Find out what your PFD is for your HID lights and compare them to the LED's numbers.

Prove it with a pic of finished product.
 
Yah lumens only matter if the par is proper. no point in 10000000 lumens of pink light. Just an example. i know nothing about pink light. Why does everyone say penetration? I would say that led per watt of high quality would have a smaller footprint than a hps bulb. Therefore more peno. 500 watts of leds can fit in a smaller space than any bulb of equal wattage. that means denser light at the source and more penetration. Also all other values rival or excede hid. Also everyone talking lumens i can guarantee most don't have their 1000 watt hps within a foot of the plants. why have 150000 lumen hps higher above the plants when you can have less initial wattage and lumens closer to the plant. its the same thing but more efficient. also cooltubes lose lumens even though you can go closer
