I compare the Wuben C2, C3 and L50 - three of Wuben's most popular flashlights. I'll go through the differences and recommend to you which one you should get, depending on your situation.
The Wuben C3 is a tactical-style flashlight that features an OSRAM P9 LED. The kit I purchased on Amazon includes a protected 3000mAh 18650 battery (Wuben branded).
