Ultra high efficiency circuit design

The C3300 Extreme circuit dominate the output competition with its ultimate power management ability and proven stability.

Reliability that you can count on

We design this circuit to survive the toughest torture environment including: 1) repeatedly over-night burn-in test w/ minimal cooling, 2) over input voltage test of up to 13.5V, 3) over-driven output current test of up to 3.7A, and 4) high temperature duration test.

Our experienced electronic engineers ensure all components are working at its maximum efficiency and highest stability with the optimally planned and implemented circuit pcb layout. All chosen electrical components in this circuit design have good amount of headroom to ensure high stability in long term usage.

Excellent runtime and flat regulation

G25C2 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 flicking.

At highest brightness level, G25C2 current regulates for 1 hour using two EAGTAC CR123A batteries. With two 3100mAh 18650 batteries (using 4 cells body extender) you get about 2.7 hours of runtime on high (1.9 hours with energy saving feature turned off).

The current regulation control method allows the just right of amount of current going through the LED. This results in constant brightness output regardless of battery type, LED variation, and temperature change.
