Duration: 21:47

This video from Mrgunsngear provides an expert-level breakdown of weapon light terminology, specifically lumens vs. candela. It explains how candela dictates beam intensity and throw, crucial for identifying threats at distance and overcoming photonic barriers. The guide also touches on the trade-offs of high candela, such as potential indoor splashback, and compares various Streamlight and Surefire models.

Quick Summary

Candela measures the intensity of light in a specific direction, determining a weapon light's 'throw' or focused beam reach. High candela is crucial for identifying threats at distances over 130 yards and for penetrating photonic barriers like headlights or smoke, though it can cause indoor splashback.

Frequently Asked Questions

What is the difference between lumens and candela in weapon lights?

Lumens measure the total light output (volume), while candela measures the light intensity in a specific direction (focus/throw). High candela is crucial for long-distance visibility and penetrating light barriers.

Why is candela important for weapon lights?

Candela determines the 'throw' or reach of a weapon light's beam. High candela allows you to identify threats at greater distances (over 130 yards) and cut through obstructions like headlights or smoke, known as photonic barriers.

What are the downsides of high candela weapon lights?

Extremely high candela lights can cause 'splash back' indoors. If the focused beam hits a close-range surface like a white wall, the intense reflection can temporarily blind the user.

What is a photonic barrier and how does a weapon light help?

A photonic barrier is a light source that obscures vision, like oncoming car headlights. High candela weapon lights can overpower these barriers by focusing intense light, allowing you to see past the obstruction and identify potential threats.
