Bright as the sun - SureFire M600P Fury Scout Rail-Mountable White LED WeaponLight w/ 600 Lumens

Exceptional light. Very bright and uniform. During a recent night training exercise, pressing the light button illuminated a whole row of targets. The other student's lights couldn't even be seen. It was light the sun. Amazing!!!

The external touch switch, on the hand, is marginal. Pressure to activate is higher than expected, and it is just another possible failure point. Suggest mounting at left 10:30 position and using your thumb while hand is on the Handguard to depress the activation button into the momentary position. Works perfectly like this.
