Purpose and audience

This 150W halogen lamp produces 2700 lumens of warm white light at 2900K with a CRI of 100. It suits ceiling fixtures, track lighting and showcase displays in residential or commercial settings. The frosted finish diffuses glare for comfortable illumination.

Deciding specification

The BA15d double contact bayonet base is the single detail that determines fit. Verify the socket type before purchase because the lamp will not seat in screw or single contact holders. The 120V rating matches standard mains supply.

Build integration

The lamp operates directly on 120V mains without a transformer or ballast. It frees the installer from external gear and fits existing bayonet sockets. Rated life is 2000 hours so plan replacement cycles accordingly. Not for buyers who need dimmable LED equivalents or lower wattage options.
