Surefire is now marketing a few 100 lumen tacticals

Surfire L4 Lumamax

There's also their L2, L5, Ultra, and G3 LED variants (the G3 is only 80 lumens but the batts will last a bit longer).

Innova also has a decent tactical at 100 lumens.

I've seen one or two out there pushing the output up to 120 lumens. I've not had a problem myself overdriving LEDs a bit, but at 4 watts output, I would start to worry more about the heat dissipation.

Those Surefire LED lights are not going to fail you.

Dorcy 120 lumen 6 watter

Here's one of the 120s. For $40 that ain't bad, but it ain't no Surefire. Those three AAs will suck down quick at 6 watts.
