Burst Mode Explained

When using a high drain IMR RCR123 cell, the Alpha Gen3 enters a 10-second burst mode of 800 lumens, and then begins gradually tapering down to a regulated 535 lumens over a period of 30 seconds.

When using a primary CR123 cell, the Alpha Gen3 enters a 10-second burst mode of 535 lumens, then gradually tapering down to a regulated 435 lumens over a period of 30 seconds.

The user will not see an abrupt drop in brightness after the burst mode.

The decline in brightness is very gradual. This design is intentional as to not distract the user during a possible critical moment.

The brightness of the burst mode may be more easily perceived if the flashlight is cycled off after about 30 seconds and then back on again. The brightness of the burst will be noticeably brighter when powered back on again. (It is not recommended to “re-burst” too many times in a row, however, as it will generate a lot of heat and it will drain the battery very quickly.)

(See the expanded graph below that shows the first 1 minute, 40 seconds of runtime. It shows the gradual decline in brightness after burst mode more clearly.)
