Review on Stay Lit in Emergencies: Rechargeable LED Bulbs with 1500mAh Battery Backup - 15W, 80W Equivalent - Ideal for Power Outages at Home by Sharon Griffin

I bought 10 rechargeable LED bulbs of this type. Revain replaced 8 of them. None of the 18 worked as advertised. I think I'm giving up! Good idea. None of them lit for more than 30 seconds when first screwed in. Left some in lamp overnight but no change. They were supposed to work like a regular lightbulb, but none of them worked. They work with a small switch or in your hand, but neither will work in a lamp. None lit up when I turned off the power in the room where the lamp was located. I got interested in them when a friend showed me 4, she connected to QVC. They worked when we had a power shortage. She said their color changed when they attacked. Neither of them showed signs of attacking.
