The NEW Ushio HPL 550W Lamp (550W/77V, 2000 hour) is a high-output halogen lamp designed for theatrical and entertainment lighting, including use in ETC Source Four fixtures. The high performance USHIO HPL+ lamp has been redesigned to be the most powerful HPL ever. Its ultra-compact filament geometry now improves the optical efficiency of your ETC Source Four fixtures to produce up to 20% more fixture lumens. That’s up to 20% more light from the same fixture as compared to the old lamp design.

Performance for ETC Source Four and Similar Fixtures

Built around an ultra-compact 4-C8 filament, this HPL+ lamp is engineered to help your fixture optics capture and project more usable light. With a 3050K color temperature and clear T6 envelope, it supports the warm, consistent output typically expected for stage wash, key light, and front-of-house applications.
