i have some and use them all the time -- i take them campimg and take some extra batteries to that i can recharge by solar during the day and use them in insta bulbs in the night
night light -- no -u will have to keep ya batteries charged all the time -- made for use in closets and stair cases -- for power outages -- -- full charge these will last around 5 hrs and then replace the batteries -- like i said rechargeable batteries are best
i gave 4 of these i got here on listia --they use 4 aa batterys -- and are around a dull light as a 25 watt electric bulb -- they are great for closets and for star cases and for power outages - and also for camping -- the bulb is plastic and durable - if u drop it it wont break - its best to use rechargeable aa batteries for this -- i have some so im gonna bid this auction
