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.
Inside the C3300 Extreme
This highly efficient synchronous buck current regulated circuit controls the precious amount of current that goes through the LED at all output levels. This results in constant brightness output regardless of LED variation, battery voltage, and temperature change. The Low EMI management and quick soft-start design provide clean electricity for the circuit and LED to enhance their service life.
Our synchronous buck converter is more technologically advanced and compact than regular buck converter. It also allows more board space for our exceptionally low DCR mosfets, rugged & shielded power inductor, and low ESR tantalum capacitors. This together leads to very high efficiency and low dropout voltage which allows single 18650 to regulate at turbo for most of the runtime.
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.
