What Does IPX4 Water Resistance Mean for a Headlamp?

You'll see ratings like IPX4 on headlamps and other gear, but what does it actually mean for using your light in the rain?

What IPX4 means

The "IP" code rates protection against dust and water. The "X" means dust isn't separately rated, and the 4 means the device is protected against splashing water from any direction — rain, sweat and splashes.

What IPX4 can and can't do

• Can handle: rain, snow, sweat, hose splashes, working outdoors in wet weather.
• Can't handle: being submerged underwater or jets of high-pressure water.

Quick answer

IPX4 means your headlamp is fine in rain and splashes but should not be submerged. For most work and outdoor use, IPX4 is exactly what you want.

The BeamWard headlamp is IPX4 water-resistant — built for rain, snow and sweat.
