I purchased 2 of these lights for my artwork thinking I would receive a quality product based on price.One of the transformers did not work but was quickly replaced.Herein lies the rub....After several months, one of the fixtures began emitting a faintly noticeable bit of smoke. A couple days later the bulb did not light. I went to replace that bulb & I found the fixture was brittle & crumbling. The other is still working fine but I now am concerned about the safety of the product.
