Light Archon Keystone Ceiling Lampholder, E26 Medium Base, White

The Light Archon Keystone is the workhorse ceiling lampholder for closets, basements, attics, and utility rooms: a white impact-resistant nylon body, an E26 medium-base socket rated to 660 W and 125V, and nothing to go wrong. Choose the keyless body for wall-switch circuits or the pull-chain body where local control at the fixture is faster.

The Keystone mounts directly to standard ceiling junction boxes on the included screw slots and wires with two terminal connections. Light output, color temperature, and dimming follow whatever E26 lamp you install, from a 9 W LED to legacy lamps, so one holder covers service work across decades of housing stock. Both bodies are UL and CSA listed; the pull-chain variant adds a 1-way on-off switch with a durable bead chain.

Frequently Asked Questions

What box does it mount to?
Standard 3.25 in. and 4 in. ceiling junction boxes; the slotted holes span standard box screw spacing, so it lands on round pans and octagon boxes without adapters.

Keyless or pull chain: which do I need?
Keyless when the circuit already has a wall switch; pull chain when you want on-off control at the fixture, such as closets or attic runs without switching.

Which lamps does it take?
Any E26 medium-base lamp within the 660 W socket rating: LED, CFL, or incandescent. Output and color temperature follow the lamp you choose.

Is it dimmable?
The holder itself has no electronics. On the keyless variant, pair a dimmable lamp with a compatible wall dimmer; the pull-chain variant is on-off only.
