UMAGE Acorn Plug-In Pendant with LED Bulb
Inspired by acorns beneath majestic oaks, Jacob Rudbeck's small pendant holds a bright world inside its glass shell.
Three parts — a soft silicone cup, a smooth glass shell, and a kernel in a metallic finish — interlace in a dainty symphony. It is made in China for UMAGE's Copenhagen studio and plugs in without hardwiring.

Common Questions
What does plug-in mean for this pendant?
The plug-in Acorn powers from a standard outlet, so no hardwired ceiling connection is required; UMAGE also offers a hardwired version if you prefer a permanent installation.
Which bulb should I use?
The Acorn takes a light source of max 15W LED with an E27 / E26 base. If you're unsure which bulb to choose, UMAGE's bulb recommendations sheet can guide you.
How do I clean the glass shade?
With a soft, lint-free cloth. For smudges, spray glass cleaner onto the cloth rather than directly onto the fixture, and avoid abrasive materials that can scratch the surface.
