My daughter has breathing problems and we've literally tried everything.  Some suggested a salt lamp. So we decided what the heck! why not?  So we ordered one.  As for the health claims on salt lamps I can't say it did anything.  
But it puts out quite a bit of light, especially for the bulb being in the middle.  It lights my daughter's room up, and makes a perfect night light for her.
So if anything its a fancy night light.
We're happy any ways.  thanks Wayfair!
