I found this little light in Radioshack yesterday ,it has 1 led(very bright),a good on/off switch,measures about 1.5"wx2"Lx.5"thick and weighs about an ounce.I carried it around on my belt outside for several hours yesterday to charge up and left it on last night.It was on about half hour before I fell asleep so I dont know how long it lasted(package says 1 hour per full charge)but it was going strong when I fell asleep.Not bad For 5 bucks.”
