I used to be a Mag Lite guy, but they pretty much haven't been keeping up with technology.

Now I have 2 of these: Stinger and I'll never go back to Mag.

If 15,000 candlepower isn't enough for you (and there's no reason it shouldn't be), there's this: Stinger XT.
If 45,000 candlepower isn't enough, the UltraStinger has an output of up to 75,000 condlepower.

The best part of all of these lights is that you put them on the charger and leave them there until you need them. I'm not sure what the difference is, but for some reason Ni-Cd's don't have memory issues when used with flashlights. Or maybe it's their Ni-Cd's.

You can buy them on most any Snap-On or Matco truck, just ask your local shop when the tool trucks come by or follow one to their next stop. There are probably other places to buy them, but I don't get out much and the tool trucks drive to where I work once a week <img src="/forums/images/graemlins/notooth.gif" alt="" />

My first one came with an A/C charger as well as a separate D/C chrger. I lost the light for a while, and bought a second one thinking I'd left the first in a customer's car. Worked out pretty well since now I have one for the truck and one for work.
