An upgraded Gladius, as others have mentioned, can approach your 200 lumen criterion. An SSC P4 LED upgrade is probably in the 160-170 lumen range.
Another alternative is the OpticsHQ reverse multifunction tailcap and LED drop-in kit for the SureFire 6P family.
See my review
here.
IMO, the OpticsHQ user interface is superior to the already excellent Gladius UI.
The downsides of the OpticsHQ tailcap IMO are:
- Buttons use glow in the dark caps (target indicator -- I'd blacken them out with a permanent marker).
- Tailcap is not universally compatible with other LED drop-ins (for example, it doesn't work right with my Deal Extreme 6090).
- Tailcap is designed to work with the current generation of SureFire bodies. If you use the tailcap on any old, roundbody style SureFire 6P, you may need to add a washer/spacer to ensure electrical contact.
- Tailcap side button is glitchy when trying to get into the lowest brightness setting. A very quick button press results in the light turning on for a few seconds, and then suddenly turning off by itself. A longer button press results in entering a brightness mode 1 or 2 steps above the minimum level, but at least the light doesn't turn off by itself.
- Tailcap draws power even when the light is off (OpticsHQ claims 5-10 mA, which seems rather high to me)
I can live with the first three items, the fourth one gives me pause (immediate max brightness mode and immediate strobe are reliable, which are key for me), but the last one may be a dealbreaker.
If the power draw really is 5-10 mA, then that translates to 120-240 mAh per day. Since Li-ion rechargeable 123A sized cells typically have capacities around 550 mAh, that means battery life of only ~2-4 days, and that's assuming no use of the light itself.
(Edit: OpticsHQ has informed me that the power draw for their tailcap is 0.5-1.0 mA when in the OFF state)
I've experienced some apparent short life recently with my OpticsHQ setup, but am not 100% sure if the light was accidentally left on or not. So, I'm running some daily measurements of cell voltage. So far, the light has lasted about a week without running down the AW-brand 123A cells, so maybe the tailcap power draw is less than 5 mA.
