Hi-
My 48" Giesemann Spectra is making a crackling sound inside the fixture when my T-5's start up for the day and then gets louder throughout the day when the MH's go on. This just started happening within the last week or so. The fixture is only a year and 3 months old. It has 4 (54w) ATI bulbs and 2(250w) Radiums bulbs that were replaced 2 months ago. I went down to the basement to see if the ballast were making noise but they are not. This noise is coming from inside the fixture. When I shut down the lights the cracking continues for like 30-40 seconds. Has anyone ever had this issue or know what it could be?
Thanks
Ed
