W F Harris Lighting 150-BK PAR38 lampholder black 150W

What this lampholder does

The W F Harris Lighting 150-BK is a surface-mount PAR38 lampholder rated for 150 W at 130 V AC. It accepts a standard medium-base E26 bulb and meets UL 1598 safety standards. The black polycarbonate housing weighs 0.35 lb and measures roughly 5 in by 5 in by 5.25 in. No lamp is included in the package.

How it fits into a build

The fixture mounts directly to a flat surface and provides a single light head for PAR38 lamps. It frees the installer from needing a separate junction box cover because the housing itself serves as the mounting point. The medium-base socket works with common incandescent PAR38 bulbs, so no special adapters are required. Wiring connects through the back of the unit to standard 130 V AC supply conductors.

Thermals noise and power draw

The lampholder is a passive component that draws no power of its own; all consumption comes from the installed bulb up to the 150 W rating. Because it has no moving parts or electronics, it produces no audible noise during operation. The polycarbonate housing dissipates heat from the lamp base under normal use. UL 1598 listing confirms the design handles thermal loads safely at the rated wattage.
