It is an OK light. Nothing special. After playing with Lux light you might be disappointed. It is all plastic and feels medium cheap but it would get the job done if all you were doing was reading a map or looking for the key to the car that you dropped on the floor. I suppose, in a pinch, you could use it to find a better flashlight in the trunk of your car. Yeah, you could probably use it to change a tire on a car. It is nice to keep in the glove box and it is nice that it charges in the car.
It has a fair amount of light coming out of it and I would expect it to last about 30 minutes. It doesn't have regulation circuits in it. The light has a single Nichia type emitter with a magnifier in front that puts out a bluish moon beam. The switch feels, what is a nice way to put it, ahhh, cheap.
If I wanted to doctor it up I would paint the insides so the light beam wouldn't shine THROUGH the plastic casing. I might add some BBs in it so it would feel like it had more weight.
The light does have enough room in it for modding. Can you say "Use a leftover Lux emitter?" It would have room in it.
The light is useable. It would be fun to mod.
