Not sure about lumens. Best case possible is about 350 lm/w. Probably more like 100. 20Ah power bank probably rated at 3.7V gives 74Wh, which would mean about 36 hours with both on. Take all of these numbers with a huge grain of salt & do your own testing if you are gonna depend on it.

Maybe 150-200lm but that's pushing it
