High-Output Halogen Lamp

This SYLVANIA halogen bulb delivers 27300 lumens at a 3200K colour temperature. The double-ended design uses an R7s recessed single contact base for secure installation. It operates at 1000 watts on a 120 volt supply. The OSRAM-manufactured lamp produces a bright white light with a colour rendering index of 100.

R7s Base Compatibility

The single decisive specification is the R7s recessed single contact base. This fitting must match the socket in your fixture exactly. No other base type will work with this lamp. Verify the holder dimensions before purchase to ensure a proper electrical connection.

Life High-Intensity Users

Suitable for professional lighting, stage, or studio applications where maximum output and perfect colour rendering are required for brief periods. The rated life of 300 hours makes it impractical for general home lighting or fixtures that run continuously. Buyers needing longer maintenance intervals should consider lower-wattage alternatives.
