Got some LED bulbs for a bin full of old D cell Maglites I still have lying around. $8 per bulb to avoid tossing 8 old 3/4 D cell flashlights in the garbage.
Definitely brings the old gals back to usability. Only 100 lumens, but way better than the old incandescent bulbs. Rated to 3W @ 9V. So in a 4 D (6V) flashlight it should run for about 36hrs. I'm gonna test one with reg alkaline batts.

Camera on manual adjusted as close to what I am actually seeing at night on basement stairs. I can't beleive how terrible old flashlights were when I was young. We're so spoiled now.
