These appear to be nicely constructed and I love the color of the fixtures. I truly like the globe is made of glass and not of plastic, which would discolor. I ordered 5, none lit up after 36 hours of charging under a fluorescent fixture overnight. Is it due to the cheap 500 mAh batteries provided or the solar panel capacity to recharge them? I ordered some new Amazon AA 2,000 mAh replacement batteries to try out my theory, perhaps also increasing the brightness too? Wish me luck, I really want to keep these and not be sending them back. I wonder how much testing Pulse does on these?
