Query: Power failure light whose power eventually fails

When I saw these at the hardware store for about $10 I thought they were pretty nifty and got two of them. When they worked, they were quite nice. Over time, whenever I'd try to use one as a flashlight I could tell the light kept getting weaker. Finally, around the 6 month point, they failed to work at all (the two failed within a week of each other).The fact they're marketed as lights to be used during a power failure is comical- as they're the antithesis of a dependable backup & 100% destined to eventually fail. In a way, I suppose they are power failure lights after all.
