You're probably going to see a good little jump in price for a solid light with a strobe feature. I've used a number of lights and can offer opinions:
-Surefire G2 Nitrolon. Not a bad light. For around $35, really hard to beat. Completely durable and reliable. Probably one of the most powerful at this price point. Downside: no lock-out, and expensive batteries. Bad combination. I believe they now offer it with the lock-out. Double check. If so, this would be a great light. Sadly, I lost it during combat operations.
-Pelican M6 LED. This was issued to me in Iraq. Solid case and a lock-out tailcap. Water resistant and held up to abuse. Uses the same batts as the Surefire, but with longer life. Not as bright as the G2, but better than a Maglite. The circuitry held up under extreme shock, but a plastic grommet in the tail-cap switch shattered under a forcible impact (similar to throwing it against the wall hard). Pelican has a lifetime warranty and will send you an RA# to mail your light in for repair. I've kept mine in a footlocker for sentimental reasons, but have had thoughts of sending it in to get it fixed as it amazingly still works, just without the click on feature.
-Maglite. I would wholeheartedly endorse them. They are virtually indestructible. YMMV, of course. But I've seen them run over by 7-ton tactical vehicles, hit with IEDs and used as hammers. Availability of cheap standard size batteries adds to their value. In having owned countless of these (I probably have 10 of them around the house right now), I've only had one issue and that was with a first-run LED. The circuits weren't very shock-resistant and it's got a short. Newer versions appear to have fixed this.
-Fenix. I haven't owned one, but I have yet to hear or read a negative review. Of course, you're going to pay quite a bit more for them vs. a MagLite. And you can get the handy-dandy strobe feature which will be great for dazzling nuisance pigeons & raccoons, as well as providing in-car disco lighting for those annoying techno beats behind radio ads. I do actually fully intend to buy one for my next light, just to see what all the fuss is about.
Good luck and be safe.
