Everyone has been waiting for this one! I have been a huge fan of the PD32 since the first version came out. Then came the PD32UE which is a great light but very "floody" The PD35 solves that problem! This light is incredible. If you are a firefighter, EMT or LEO, this is the light for you. If you are just a person who wants a kick a$$ light that ounce for ounce outperforms lights costing hundreds more....this is the light for you. This package comes with TWO Ultrafire 18650 batteries and a wall charger. The light only uses ONE battery but we give you a backup ready to go at all times in the charger for those times when you need extended run time.Are compact size and mighty output really mutually exclusive? Not in the case of PD35. Weighting only 87 grams and less than 14 centimeters long, PD35 delivers a stunning 850-lumen maximum output from one 18650 battery. Six outputs including strobe mode cover from daily use to outdoor and professional use while a simple press on the side switch is all you need to select output.
