Lumena 20W LED Corn Bulb (ES/E27) - Warm White

When a Standard Bulb Falls Short

This 20W corn bulb is built for fixtures that need real brightness rather than a standard household glow, think bollards, lamp posts, and other large exterior fittings with room to spare inside the diffuser.

Warm White, Built In

This listing is the Warm White version, giving a soft 2700 to 3300K glow that suits traditional bollards, period style lamp posts, and anywhere you want light without a clinical edge. A Daylight White 6500K version of the same bulb is available separately if you would rather match a cooler, crisper look.

How It Works

72 Epistar 2835 LEDs are arranged nine to a panel across six side panels, with a further 18 on the top, so light is thrown in every direction rather than down a single beam. Each panel sits behind its own sectioned polycarbonate cover, which protects the LEDs without blocking the output. Electrically it runs at 20W nominal, accepts 95 to 265V, and delivers around 2100 lumens with a colour rendering index above 80.

Where It Works Best

Fit it into bollard lights, lamp posts, or any large E27 fixture that can accommodate its size. If you are fitting this into a fixture other than a Lumena one, check there is enough internal space and airflow around the bulb before installing, since its 360 degree output needs room to breathe.
