LEDs
    #3287713 - 10/28/04 01:49 AM (13 years, 6 months ago)

I am going to be constructing a LED circuit wiring 2 super bright blue LEDs (470 nm) in parallel each with their own resistor.

2 questions:

1) do you reccomedn anything other than 470 nm? (i've heard optimum numbers range between 460 - 480 for cubensis)
2) what is the significance of the MCD value?

Out of these two choices...

"BLUE Super Bright Led
470 nm / 5500 mcd / 15 Degree Viewing Angle"

or

"BLUE Super Bright Led
470 nm / 2400 mcd / 30 Degree Viewing Angle"

which ones should I get?

thx a lot

get wider viewign angle...more light coverage.

Good luck!

It's simply how bright the light is. I don't think it matters as far as mycelium is concerned.

Cubensis responds to distinct peaks at 360, 440 and 460nm.

It has always been my opinion(and goal) that one should make an LED matrix using 360, 440 and 460nm LEDs. It would be much closer to natural light(minus all the greens and oranges and reds, of course)..

Natural smatural. How often do you see this in nature?



I'd go with the 470 wide angle one. Like discman said, I don't think the brightness will matter..they'll be plenty bright enough as is.

i will only be fruiting 4 1/2 pint cakes in a 20 gal bin. do u reccomend i get 2? also, would u advise i get the 472 nm super bright blue leds with a 45 degree viewing angle? i'm sure either ones would do the job well..just wondering

One would work but I'd go with 2 and the 45 degree viewing angle.

Put one to each side (longwise) but not right on the side, just near it, to make way for that nice big viewing angle.
