Hi all,
I'm new to this forum and after spending a bunch of time lurking and researching, I am no closer to finding a solution. I'm working on a pet project and I'm trying to create an illuminated panel in a cabinet. The panel is about 4'' by 4''. I want the panel to be completely illuminated but to only come on light to come on when it gets dark; basically just be illuminated at night. The problem is I only want the panel to be illuminated with two or four AAs and I'd like to get at least 30 days, if not more, out of them. When doing the calculations and taking into account battery capacity and looking at the draw of bright LEDs (at least 25 mA) I can't figure out a way to do this. Does anyone have any ideas? Thanks for the help.
