I use a xenon type fixture made by Kichler. Very easy to install and the lamp is rated for 10,000 hours. I have used many of the Alkco hg series with mixed results. Frequent complaints were noisy transformers and fast lamp burnout. One problem with the Kichler is lamp breakage. The way they pack the fixture the lamps end up broken a good 70% of the time. My supplier provides me with plenty of free lamps but the real issue is getting all the pieces of glass cleaned out of the fixture before installing over food prep areas. I have e mailed Kichler twice about this with no response. I would be interested to hear of recent experiences with the Alcko fixtures. Good or bad. Perhaps it's time to try them again. Do you guys dim these fixtures and what type of dimmers do you use. I use electronic low voltage dimmers I buy at $68.00 a piece. Marked up 30% for a much better profit than a regular switch.
