Product review (2 stars): Internal Light Burnt Out at 2yrs, $325 to Repair
2 years after the purchase, and 1.5yrs after install, the internal light burnt out.  Repair would have been $300 for labor due to poor design, so we will live without an internal light for the remainder of the light.

This is pretty disappointing for such an expensive purchase.  I would have expected more reliable parts.
