We bought 8 of these to light our barn for a few hours each night. We charged them all properly and had them mounted overhead. The lights at full brightness only last 2 hours and became so dim there was little point. We charged them again and this time none would produce the full brightness of that first time. They have gotten progressively dimmer with every charge. Incredibly disappointed as these are $29.99 at Canadian Tire each and we have never really got full use out of a single one.
Bottom Line: No, I would not recommend this to a friend
