The Serfas SL-255 is designed as a bicycle headlight but works fine as a pocket sized flashlight, runs on a pair of AA batteries, and claims to be 255 lumens on the brightest setting -- which seems about right, subjectively speaking. About $30, pretty close to the price of the most recommended mini-flashlights like the Fenix.

Three brightness settings, one flash mode. Default from off to on is always steady low; then medium, and high. Enabling flash requires a two-second continuous press. A one-second press turns it off.

The Serfas is easy enough to detach and reattach from/to the handlebar that I find myself using it more often now than my older mini-flashlight. It's lighter in weight than my older metal bodied 4-LED mini-flashlight, with a more neutral white (my older flashlight is very blue), and much brighter, with a strong circular beam at center and less bright squarish outer beam. The squarish shape feels about as good in the hand as a cylindrical flashlight, and grips well due to the texture. It's heavy duty, rigid plastic, not metal, so it should be comfortable to hold barehanded in cold weather.
