Does anyone know if i can use leds in the 465-470 wavelenth for veg and 625-630 for flower im talking thousands of little lights in a small cage style grow but firstly can i use this wavelenth i know optimal are 450 and 650 but am i close enough? any help is much appreciated, hoping to go all out this year new tech led, aero, scrog all gonna be home made keep up the good work guys n keep on growin

I don't know that much about the technicalities of led wavelengths to be honest.
When i looked into building my own led boards i was going to use these for blue.

Product Specification
[FONT=verdana,arial,helvetica,sans-serif]Prolight Power LED blue 5 Watt[/FONT]
[FONT=verdana,arial,helvetica,sans-serif]Technical Data:[/FONT]

[FONT=verdana,arial,helvetica,sans-serif]Case: Star-PCB with Aluminium-Cooler
Viewing Angle: 140°
Power: 7,1V
Current: 700mA
Wave Lenght: 470nm (blue)
Brightness: 40 Lumen[/FONT]




PowerRecommended Resistors5V -9V 2 Ohm / 2 W12V 8 Ohm / 4 W13,8 V (car) 9 Ohm / 5 W
And these for red.

I have no idea of the actual ideal and correct spectral output of leds for growing,but i reckon that these will work just fine:blsmoke:

One thing to watch with LED's is the Angel compared on how close you want the bar to the plants, and how much you want them to stretch, and and how much lighting you will be useing..

When useing a wider angle, this makes you need them a lot closer, (or they strech), then if you have a smaller angel.. I have found threw my second LED VEG that wide angel's on the side and narrow on the top seems to work the best... Narrow ones i am useing are 8-15 degrees and the wide are 100-120 degrees.

A little background on my LED experiance.. This is my third light/light system i am making now, and will be making a complete post of what i have found soon..

I had intended to use the flexible waterproof bars.
The leds i have posted on have a 140 degree viewing angle and if you wish you can also get miniature reflectors for each one to increase their viewing angle and intensity.
Personally i am no longer going to bother with leds as i think professional cfls are probably a better and cheaper bet with better results than leds:blsmoke:

I was just looking at this today on the web... interesting stuff on led's not very great technical data but they have the spectrum data if you navigate around the page..
LED Grow Lights.com Home Page

im wondering my self if this is the way to go.. now if we only had a fry's out here on the east coast.. i could build my own lol

I think LEDs still have a way to go before they are superior to HPS/MH or CLFs but
they might be the future way to grow.

maybe off topic, but I think the future lies in sulphur plasma lamps, and i cant wait to get my hands on one!

My 2 cents,

I believe leds are going to replace all the other lighting indoor growers presently use. There is no other way to control the spectrum of light like you can with leds.

Sure it will take a while getting used to them, and as soon as we do create a demand the prices will drop. Well demand and new techology combined.

Just like everyone else I want to see them in action.
So anyone using them Please Post away!

I also agree but even the leds that i checked out at a wholsale suppliers and posted here with a good output and the correct wavelengths are 15.00 euros each bare.
Until they fall in price they are a luxury item:blsmoke:

For those interested in the sulphur Plasma Lamps:

nlite SULPHUR PLASMA LIGHT

They are way too expensive for most growers, hell LED's might even be cheaper, but LG Korea has already started marketing them as replacements for street lights and for lighting skyscrapers. But these are not for the hobby grower, unless you have a setup that needs at least 3 1000w HPS bulbs, these wouldn't be worth it anyway...

not to mention it's heavily weighted in the green spectrum which is not ideal for growing.
