20MM conduit bulb holder



Our E27 20mm conduit threaded bulb holders are perfect for making industrial steampunk style lighting. Use with matching 20mm copper conduit pipe to create quirky and unique pipe lighting.

Note, this bulb holder won’t work with fabric cable as the hole is too large and there’s no cord grip.

Product Details



Our E27 20mm conduit threaded bulb holder tarnished copper has been created to use for industrial or steampunk inspired lighting features. Affix our tarnished copper bulb holder to the ends of 20mm conduit pipe to create gorgeously unique lights for your interior.

We love our tarnished copper conduit bulb holders with squirrel cage filament light bulbs. They have an authentically vintage feel that looks gorgeous against the rustic copper finish. Plumbing style lighting looks particularly good in industrial style kitchens. Think polished concrete floor and exposed brickwork – grey and navy tones work really well.

Tarnished copper has an authentically weathered finish that looks fabulous in industrially styled rooms. With stunning tones of teal, navy and charcoal eddying across the surface, it makes a real statement feature against white walls. Alternatively, use against dove grey or navy walls to create a more rugged vibe. To complete your vintage look, add one of our filament light bulbs – this gorgeous collection of bulbs is both beautiful to look at and casts an ambient light into your interiors.
