I have purchased two different 'Coast' brand lights at Lowes and think both are great.
One is carried daily as a work light and the other is kept in the car.

Their web page does seem to give different outputs from what are listed on the packaging in the store, but I like the fact that you do have a lumen output listed and that you can actually test them in the store.
The same lights are available at places like 'Sportsmans Warehouse', but usually run about twenty dollars more.
I haven't found anything I like more but your application may be different from mine.
Good luck.
