Product review (3 stars): Neither light works any longer. It's not the lamps ...
Neither light works any longer.  It's not the lamps, I've replaced them.  Can't get manufacturer to return my email or any contact what-so-ever. Thinking this was a mistake to purchase.
UPDATE - Spoke to Z Line, they are sending out a new transformer that I will be able to swap out (thank goodness for the three year warranty). I've upped this to three stars for the friendly customer service.  Still think (if it is the transformer) that it should last more than eight months.  We'll see what the new part can do.
