OSRAM SYLVANIA 12 pcs HPL 575w /115 (UCF) halogen bulb
- Product Review (submitted on October 30, 2008):
- I ordered these for my ETC Source 4 Par, ParNel, and S4L production lights. They are a correct fit. I ordered these long-life bulbs to replace some GE branded bulbs. The brightness is a little off, but they will last much longer.
