Tactical Flashlights

Flashlight Standards

Flashlight manufactures that adhere to FL-1 Standards provide specific information about the products. This includes:

Light Output - The Lumens rating that shows the total amount of light that comes out of the front of the flashlight.

Peak Beam Intensity - Measured in Candela this is the brightest point in the beam. Where Lumens tell how much light is coming out of the light in total Candela measures how bright the brightest point of the beam is.

Beam Distance - This is the measurement in meters of the distance at which the intensity of the beam reaches 0.25 lux which is the approximated amount of light of a full moon on a clear night.

Impact Resistance - Measured in meters this indicates the height from which you could drop a flashlight onto concrete and it still work properly. Dropped samples must not exhibit any cracks or breaks, and must remain fully functional in order to pass the Impact Resistance test..

Runtime - Runtime is defined as the amount of time, rounded to the nearest quarter hour, until output drops below 10%.

Water Resistance - Water resistance is stated using the IP rating system. 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
