As the trend seams to be moving away from small die led's of specific colors, to me it seems that led has lost some of it's "cool" or "NASA" factor.
Anyone else feeling the same way?

monos are still more efficient, but agree the cool nasa factor is fadingAs the trend seams to be moving away from small die led's of specific colors, to me it seems that led has lost some of it's "cool" or "NASA" factor.

Hell no! Just getting warmed up.As the trend seams to be moving away from small die led's of specific colors, to me it seems that led has lost some of it's "cool" or "NASA" factor.

Are they?monos are still more efficient, but agree the cool nasa factor is fading
A single white led has a lower eff. then a blue one. stokes loss is more then 10%Are they?
There's no way white LEDs will be more efficient. They're just blue ones covered with phosphor.
And yet the most efficient LED available is white.
Why is that?
The price of some of these lights are just stupid thats why some stick to hps.As the trend seams to be moving away from small die led's of specific colors, to me it seems that led has lost some of it's "cool" or "NASA" factor.

would all those individual blue bulbs be as useful to us?A single white led has a lower eff. then a blue one. stokes loss is more then 10%
A cob is a matrix of 11x11 leds. at 700mA a single led in a cob now runs at <70mA.
Underdriven by factor 5 for a 1watt led.
I completely agree with that quote. I'm also tired of all this efficiency talk when its mostly theorized calculations based on individual diode performance.. from a data sheet. To me, gardening efficiency should be based on a Grams Yielded/ Luminaire Watts Drawn. Electrical efficiency is pretty negligible when you are talking a 4x4 space or smaller (Not referring to 1000W Hps).Hum, I like what I saw another member post somewhere - something along the lines of "I measure efficiency in weight"
try producing the same amount of 660 red with a white cob, then you can compareBlue leds are more efficient than white, but red leds are not more efficient than white. Also, blue + red is a terrible spectrum for flowering weed. You'd need amber, which means you need efficient amber leds.
There's a good reason everyone's using white leds now... It's because people like to copy success.
Well the 1st part of that is really already spelled out under the term of "efficacy".....which is why we all are here [well most of us] in the 1st place, trying to grow better and more..... punI completely agree with that quote.

If a high efficiency set-up costs 2-4 times what an economy set up costs (referring to COB's), but yields the same, what have we actually gained? (still talking small spaces). How long would saving 100-200 watts per month take to recoup the initial investment for a "high" efficiency light?
