It's a very bright led flashlight and depending on the battery depends on the brightness.

As an old nighthawk instructor pilot, I love this flashlight with its red lens.
I hate using more light than I need in the dark. The red lens is usually more sufficient to keep me safe and get what I need to do done.
It takes 30 to 45 minutes to fully night adapt and bright white lights destroy the substance rhodopsin that allows us to see in the dark. The rhodopsin will build back up given the necessary time.
If maintaining night vision is important to you, this light is a good choice. I keep mine in a flashlight holster clipped to my pocket so it's always there when I need it.
Another similar flashlight with only the clear lens had a lanyard attached to the end. This flashlight doesn't have a hole for a lanyard to be attached. But with the flashlight holster, that's not as important.
I love my red lens flashlight!

Pros:Powerful little light. Has clear/ red and green lenses. Comes as a pair. Has a magnet end

Perfect. Exactly what I needed to look out at night when my the neighborhood dogs are barking.

This is a very bright flashlight. I love how the light can cover a broad area and the removable red filter was just what I was looking for.
