I only use a flashlight when I'm blood trailing a deer after dark. The one I use is a Streamlight Scorpion. Wow is that thing bright. It is brighter than every big flashlight I've ever seen. Being an electrician, I carry this light every day at work. Almost everybody that I work with carries a light. These are the brightest. There is a price to pay for using this light... It eats batteries! It uses two camera photo cells at $8 a piece! They only last 2 hours of constant use. If left on in its holster, it will burn a hole through its case and your shirt. Oh yeah, it will blister the lens also. You really have to get used to this one for every day use. The main reason I continue to use it is because I have a never ending supply of batteries.
