I browsed the Kindle Boards forum and several people there have also gotten bad PWs with darker what they call pink lighting. Mine is more tan, but perhaps there were some batches made with inferior LEDs? One lady got two PWs, one is good the other is bad. She showed them side by side. She had to argue with Amazon CS to replace the bad one, and it will be a few weeks before she gets the replacement. Apparently Amazon failed to hold back PWs for replacement purposes. It does seem like most people are getting good ones, but some of us just learned how bad QC is with Chinese made products!
