Do solar powered lights get energy from moon light?

We Answered:

Essentially, no. The moon does not produce any light rays, it reflects the light from the sun. Think of it this way, can you get tan from moonlight? Do you feel heat on your hand when you hold it up to pure moonlight?

No, because there is only a small amount of visible spectrum rays being reflected.

Does the light from an arc flash recharge a solar powered welding helmet?

We Answered:

Most welders work indoors anyways, so you shouldn't have to worry about it. I have heard, however, that it is a bad idea to keep it in a dark locker right before you use it. I have heard that they do use batteries and if you keep it in the dark too long and weld right away, it wont have the power to darken.
