NEW Ushio HPL 575W Lamp, 575W/115V, 300 Hour (Case of 10)

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.

Designed for ETC Source Four Performance

Built around a compact 4-C8 filament and a clear T6 bulb, this HPL-575/115V+ focuses output where your optics can use it most, helping maximize punch and beam quality in theatrical, live event, and rental inventories where Source Four fixtures are standard.
