will it light up a cellar entry way ?
Yes it is perfect for that use. Remember to keep it out of the elements. No direct exposure to water.
How long do batteries last in the light bar?
Using fresh alkaline batteries, expect up to 6 hours of continuous light in the high brightness mode and about 10 hours in low. That said you shouold get months of light if used intermittantly.
Will this light bar work under a kitchen cabinet?
Can this be place on a back wall 3 feet above a kitchen stove?
Yes it can. Please be aware that installing it with the peel and stick disc is not recommended for this location as the steam will lossen it. We recommend using the keyhole mounts with 2 small screws for a permanent installation.
I purchased item #22064, Jumbo Wireless Light Bar as a Christmas gift. The bottom where the batteries are installed is broke & will not stay on. Should I return item to original place of purchase?
