Can these be used to tell someone's munchies which way is up?

If its bright enough to see the shrooms, its bright enough to grow them

AFOAF is actually in the process of setting up an LED terrarium. It should be noted that while blue LED's are indeed very bright, they have a pretty short fall-off angle 10deg. I would recommend using white LEDs, they put out a brighter beam (which, since it's whiite also contains the blue spectrum) and has a 50deg fall-off.

Despite the 50? fall off of white leds, wouldn't the blue spectrum (the part that as i understand is the most important but im a newbie so don;t take my word for it) still fall of at 10??

You have to understand that blue lights have been proven (under what kind of experimental control, I have no idea) to be the most useful spectrum for the cultivation of mushrooms. This, ofcourse, doesnt mean that other colours of lights will not work.

Another user at the Forest Floor was educating me on this very subject about a week ago. Apparently he too has been looking into the use of LEDs for terrariums. (See: http://www.theforestfloor.org/cgi-bin/ikonboard.cgi?s=3be0fd7c409bffff;act=ST;f=11;t=131). Blue has been proven to induce pinning better than other colors - However, white light will do just fine, and I doubt you'd notice the difference. Besides, using LEDs (because of their size) allows you to put the light INSIDE of the terrarium, as opposed to placing the lighting outside where (unless your using clear glass like an aquarium) it has to shine through plastic which filters a lot of the light out. 2 strategically places white LEDs (say at opposite corners) should be able to provide all the light you need for inducing pinning and ensuring upward growth. In addition, there are a lot of accesories that can be purchased for LEDs such as reflectors that widen the output angle.
