NEW Ushio HPL 575W Lamp, 575W/120V, 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, delivering up to 20% more light from the same fixture compared to the old lamp design.

Built for ETC Source Four Performance

Designed for stage and architectural lighting applications where consistent output matters, this HPL-575/120V+ lamp pairs a compact 4-C8 filament with a clear T6 halogen capsule to help your Source Four maintain a bright, punchy beam. The 3250K color temperature provides a familiar warm white commonly used for tungsten-halogen theatrical looks, while the ANY burn position rating supports flexible fixture orientations.
