Ball Trough Problems & Optic Switches you will see the specks of the LED. Apparently a Fairchild MV8114 will work now that has a 660nm wave length, view angle 12, and a mcd of 1200 to 2200, and it's clear and red ECT. (

I think I found a suitable replacement at Radio S*ack rummaging through their parts bins I found two LED's Part number (276-307) 660nm, View 12, color RED clear, 1.7 to 2.4V max, and 3000mcd. Now the specks are exactly the same but the mcd rating is 800mcd more than the Fairchild brand do you thing this will make a big difference in the way it operates?
