Thanks for having me. I have been working in the local TV broadcast business for almost 20 years at stations in Western NY and North Carolina, before moving to Georgia. I work at a TV station that still has a Kliegl Bros Type SP patch panel in use. It is connected to a "newer" SmartFade ETC lighting board. We have been running into an issue with our bulbs blowing prematurely. The fixtures that we are using are Mole 3081, 5421, and ETC Source 4's. The bulbs are not blowing like a typical bulb does.... they are melting inside the glass. My ENG Dept has went and checked fixtures and the drops from the grid. Everything is pointing back to the Kliegl Type SP. Any help would be great, I can't keep feeding the monster bulbs.
