Sylvania 58738 150Q/CL/MC ESL 120V

The Sylvania 58738 150Q/CL/MC(ESL) is a high-performance 150W Super-Q® tungsten halogen lamp engineered for precision accent, display, and architectural lighting applications requiring high lumen density in a compact form factor. Delivering 2,800 initial lumens of 2950K warm white output at 100 CRI through an E11 Miniature Candelabra (Mini-Can) base with a compact T4 clear envelope, this ANSI ESL-coded lamp provides instant full brightness, universal burn position, and 2,000-hour rated service life for high-end retail showcases, museum and gallery spotlighting, and specialty architectural luminaires.

ADL Supply Expert Application & Replacement Guide

The Sylvania ESL 58738 is primarily specified by lighting designers, electrical contractors, and visual merchandising teams for high-end jewelry and fashion retail showcases, museum and gallery accent spotlights, under-cabinet task lighting, high-output cove accents, and specialty architectural pendant fixtures where the compact T4 form factor at 150W delivers the high lumen density required in small-aperture luminaires. The E11 Miniature Candelabra (Mini-Can) base is a screw-in base format with 11mm thread diameter — distinct from the E12 Candelabra and E26 Medium bases — and the fixture socket must specifically be E11 before ordering. This lamp operates directly on standard 120V line voltage with no transformer required, is fully dimmable with compatible incandescent/halogen dimmers, and delivers instant full brightness at ignition with no warm-up delay. As with all quartz halogen lamps, the envelope must never be handled with bare skin — quartz oil contamination creates localized hot spots that accelerate premature failure.

Operation, Safety & Mounting Compliance

E11 Base Specificity, Dimming & Quartz Handling

The E11 Miniature Candelabra base uses an 11mm thread diameter — one size smaller than the E12 Candelabra base common in decorative fixtures. These two base sizes are not interchangeable; confirm the fixture socket designation before ordering. This lamp is fully dimmable with standard incandescent and halogen leading-edge dimmers — trailing-edge (electronic) dimmers are also compatible with most Super-Q halogen lamps, but confirm dimmer compatibility with the specific fixture application. Never handle the quartz glass envelope or T4 tube with bare skin — skin oils deposit alkaline residues that bond permanently to the quartz surface during thermal cycling, creating localized hot spots that accelerate premature envelope failure. Always relamp using clean cotton gloves, a lint-free cloth, or the lamp's original packaging.
