Stage & Studio Halogen Lamp

The SYLVANIA HPL 575W 120V halogen bulb is built for stage, studio and architectural fixtures. It uses an ultra-compact filament design that improves light collection and output. The lamp is engineered specifically for ETC Source Four fixtures and carries the OSRAM 54817 part number.

G9.5 Medium 2-Pin Base Constraint

This lamp fits only fixtures that accept a G 9.5 medium 2-pin base with an integrated heat sink. It operates at 120V and draws 575W, so the circuit and dimmer must support that load. The 300-hour rated life means frequent replacement in high-use environments.

16460 Lumen Output Decides Suitability

The lamp produces 16460 lumens at a 3265K colour temperature with a CRI of 100. That output level determines whether it meets the brightness requirement for a given production or installation. Buyers needing lower output or longer life should select a different wattage from the HPL series.
