AR 15 Flashlight FAQ
Why Does AR 15 Flashlights Need More Throw (Candela)
More throw means the beam can lit up the environment further into the distance, to positively identify targets & control the threat at a safe fighting distance.

When Is Flood Beam More Important ?
A strong flood beam pattern is important for close quarter applications to light up everything around the shooter's to maximize situational awareness.
A balanced flood and throw light beam pattern is great for hunting, close range home defense and force on force training.
When Is Throw More Important Over Flood?
The throw performance becomes more important than flood If the identifying things far away past 700-100+ yards in low light. A focused throw beam helps to clearly see what's down range without missing any details.
A tight focused beam with tons of candela output can also help light up things through brushes and tree lines to see targets behind in the dark. A weaker throw light just can't.
