It has been over a week now. We leave them on at night and often forget to turn them off during the day because of the Florida heat. You still go strong. :) At first it scared me that the part of the bulb where the blue light should emit is white and the base is blue? I thought maybe that wouldn't make it that blue, but it's definitely very blue. I can't talk about energy efficiency, but I don't think it's bad? Would buy again.
