To pursue improvement, Microfire develope Challenger I revison III. 

With a reduction on weight, the new revison Challenger I achieves better performance.


1. Turbo mode is as bright as 3000 lumen;

2. Added a mode selecting ring, it can be appointed to switch on at your desired brightness. 

3. Waterproof under 20 meters, IPX 8



To solve the bad effort on LED lifespan caused from heat, we innovate a active cooling device, which is different from passive way to transfer heat via conduction,  is much more effective on transference of heat.

Why do we choose this device? Here is the reason.

a.  Higher Efficiency


It is a active cooling device which can make air convection between interior and exterior. The performance on cooling system is can optimize the performance of LED for higher luminous efficacy and longer runtime.



To prove the better performance of this positive cooling device, Microfire was operating a fatigue test. Take two different L500R samples, A adapts a active cooling device and B uses a metal heat sink, switch them on for eight hours constantly per day. After six months, the luminance for sample B is 6300Lux @ 2 meters, compared with the initial 9600 Lux, the luminous efficacy has reduced by 30%

For sample A, it is 8750 Lux from 9600 Lux, the active convection device save 20 percent luminous efficacy.



b.   Less weight

Less than 8 gram, the active cooling device is much lighter than traditional metal passive cooling system.  Less weigh but higher performance, it is a real tactical compact searchlight.
