Lights Education


Let’s be honest, buying a new flashlight is confusing. What the heck is wattage, candlewatt, and lux, and why do they matter? How on earth do I choose the right flashlight for my needs?

Turns out, there are simple standards to help consumers compare flashlights: the ANSI FL1 flashlight standards. Here at RAYOVAC®, we test and retest our lights against the ANSI Standards in our own R&D lighting test lab.

Below are the key ANSI Features defined:



A measure of the total power of light emitted. The higher the number, the brighter the light.


Run Time

The length of time the flashlight will run with the batteries provided.


Impact Resistance

The degree of which a device resists damage from dropping on a solid surface.


Beam Distance

The distance the light travels. A measure of how far from the device the beam of light reaches.


Water Resistant

Water splashed against the device from any direction shall have no harmful effects.



Ingress of water in quantities causing harmful effects shall not be possible when the enclosure is temporarily immersed in water under standaradized conditions of pressure and time.
