Tech Blog: 9-Volt Led Flashlight
If you are uncomfortable with the traditional flashlight design there are a few alternatives to choose from including the Pak-Lite Flashlight which combines two Super Bright LED Bulbs with a 9-volt battery. 'You get up to 1,200 hours of use on one battery. Very economical don’t you agree? It comes in several versions including the “Infared” which is to be used in conjunction with a night vision device, “Flasher” that uses white/red bulbs, and the “Ultraviolet” which makes forensic work that much easier. To get one for yourself it’ll cost $12.99 for the basic model and the other versions like the ones mentioned above sell for $29.99.'
