Satco 90-1590 6 Inch Round Porcelain Lampholder

Product Description

The SATCO 90-1590 is a 6-inch round porcelain keyless lampholder designed for utility and general-purpose lighting installations. Porcelain construction provides reliable heat resistance and durability, making it well suited for high-temperature environments where plastic fixtures would degrade. The keyless design means the socket is always-on, controlled by an upstream switch or circuit breaker rather than a pull chain. Electricians and maintenance technicians install this type of fixture in attics, crawlspaces, basements, garages, and utility rooms where a simple, durable mount point for a standard medium-base bulb is required.

This lampholder is a standard round-mount type used across residential and light commercial applications. It is commonly installed on junction boxes or ceiling outlet boxes where low-profile, no-frills task lighting is needed. The 6-inch round form factor fits a wide range of standard electrical box configurations. It is appropriate for use in dry and damp-listed locations depending on local code requirements and installation context.

Installation Notes

Installation is typically performed by a licensed electrician in accordance with NEC Article 410 governing luminaires, lampholders, and lamps. Always shut off power at the circuit breaker and verify the circuit is de-energized with a non-contact voltage tester before beginning work. Secure the lampholder firmly to the outlet box and ensure all wire connections are made with appropriately rated connectors. Do not exceed the maximum wattage rating for the installed lamp type.
