It stopped working ...
If you want something that will last for 4 months and you can't return it then buy this light.  I'm very disappointed...  I have 2 of them.  One at home and one at work.  I'm assuming the other one will quit soon... I'm going to look at other reviews now.  :(  So sad.. and now I don't have my happy light to cheer me up...
