Throw1000 m
CD/LM factor166.67

The 1500 lm output of L18 provides great flexibility. You can adjust the brightness to fit different needs. These flashlights have very high intensity. They need lots of power and make a lot of heat, this is because they have high energy output. The throw distance is the farthest distance the flashlight can light an object. Candela per lumen (cd/lm) measures a flashlight's beam intensity. It compares this to its total luminous flux or output.
