We have a situation at our Power Generation Facility concerning Light Fixtures. The fixture in question is an outdoor wall mounted High Prssure Sodium. We have a maintenance team that wants to remove the HPS Igniter as well as the Xfmr, leaving the screw in bulb holder and using a screw in flourescent bulb. My contention is that if we do this, we will no longer have a UL listed device. I feel that if there was a claim to be filed with our Insurance Underwriter due to a fire in this area, the Underwriters would certainly cite this to refuse our claim. All comments are welcome and thanks to everyone.
