Turbo boost technology is activated every time you turn on at
turbo output setting. It offers 25% more power to the LED for the first
200 seconds at turbo mode.
TX25C2 runs for 90+ hours on its lowest brightness level. The current
regulated circuit design allows constant output throughout its runtime
for all output levels without LED flicking.
At its highest brightness output, TX25C2 current regulates for 1 hour
with two CR123A and 1.6 hour with EAGTAC 3400mAh batteries. Double the
runtime with body extension tube.
Not only we care about the LED runtime, we also care about the
runtime when the LED is turned off. The standby power consumption is
only measured in merely uA level, which translates to years of standby
time period, just like your TV remote control.
