The SRT5 shoots out light that has been measured at a maximum output of up to 750 lumens. This is all possible because of the CREE XM-L (XM-L2 T6) LED and the powerful current from a single 18650 battery or a couple of CR123 batteries. At this brightness setting you can expect the SRT 5 to run for 1 hour and 45 minutes when paired with the 18650 and it will run for 1 hour and 15 minutes when used with a pair of CR123 batteries. Other tactical and practical applications can also be accomplished with the red and blue LEDs.
