After numerous power outages where I had to use a dozen or more oil lamps I decided to try one of these. I got it yesterday and tried it out. It lights up my 15 x 22 living room with no problem. Ordered two more today. I'll sell my oil lamps at a flea market and probably buy two or three more of these. Much brighter,much safer. Only need to store batteries not oil.
The only suggestion I would make would be to include instructions on how to install batteries.
