NE2 bulbs need 75-90v db supply to run. If your to use them use NE2H
as they are brighter.

Almost... White leds are biased toward blue white and incandesent lamps
were white biased toward red. Also with incandesant the color of the lens
cap was a factor. for examaple it could be red, amber, green even blue.
