Commonly Used Lighting Terms
Light Output – Measured in Lumens and is the intensity of light coming out of the flashlight on the highest brightness setting.
Peak Beam Intensity – Measures the brightest part of the beam. The value is reported in candela and does not change with distance.
Beam Distance – Measured in meters. This is how far the light will shine before the brightness diminishes.
Runtime – Measured in hours. Runtime is the amount of time it takes the light output to drop to 10% of the rated output, rounded to the nearest quarter hour.
Water resistance (IPX Rating) – Water resistance is stated using the IP rating system, and three ratings are used:
- IPX4 - Water-resistant, or water splashed from all directions
- IPX7 - Water-proof, or temporary submersion at 1 meter for 30 minutes
- IPX8 - Submersible, or continuous submersion at some specified depth for 4 hours
Impact Resistance – Measured in meters. Lights are tested by dropping them 6 times onto concrete at the rated distance.
