The Besa Luma 18 is a flush mount ceiling light. Its glass: Hand-blown Opal Glossy glass (a polished outer layer over an opal inner layer) with a clear edge that forms a halo. Lit, the opal glows warmly while the clear edge catches the light and sparkles. It is sized for kitchens, living rooms, dining areas and primary bedrooms.

Order it with incandescent lamping (three 60W A19 medium (E26) base lamps of your choice, not included) or as the LED version with a 30W integrated LED: 3000 lumens at 3000K, CRI 90+, rated 50,000 hours. The glass locks to the white aluminum fitter with Besa’s twist-and-lock bayonet, so it comes off easily for cleaning or relamping. At 17.75" diameter x 4.75" H (glass diffuser 17.25") it sits close to the ceiling.

Why we carry it

We have been curating design-led lighting since 2009, and Luma puts real hand-blown glass and a bright, long-life LED into a slim, room-filling disc. Besa Lighting pairs American design with European glass artisanship: its shades are hand-blown by skilled artisans using techniques passed down for generations, then hand-inspected at Besa’s factory in Ohio for color, pattern, thickness and size before they ship.

Buy once: durability and care

Switch off and let it cool, then wipe the glass with a soft cloth lightly dampened with mild soapy water and dry it; avoid abrasive cleaners (our advice). The LED version is integrated and rated for 50,000 hours. Installation by a licensed electrician is recommended; 90°C supply wire is required for incandescent lamping.

Frequently asked questions

What are the dimensions of the Besa Luma 18?

It measures 17.75" diameter x 4.75" H (glass diffuser 17.25"), per Besa’s spec sheet. Each glass is handcrafted, so allow for slight variation.

How bright is the Besa Luma 18 with LED lamping?

The LED version gives 9000 lumens in total at 3000K with CRI 90+ and is CL dimmable. The incandescent version takes 3 x 60W A19 medium (E26) base lamps (not included) and dims with a standard incandescent dimmer.

What is the clear halo on the Luma 18?

The opal glossy glass has a clear outer edge. When the light is on, the opal glows softly and the clear rim catches the light, so the fixture reads as a glowing disc with a bright ring.

Is the Besa Luma 18 suitable for a bathroom ceiling?

Yes. Besa rates it for damp locations, interior use only, so it suits bathroom, laundry and powder-room ceilings. It is not rated for outdoor ceilings or direct water spray.

Is the Luma 18 LED replaceable?

The LED version uses an integrated 30W LED rated for 50,000 hours, so there is no bulb to change. If you would rather choose your own bulbs, order the incandescent version with three A19 lamps.

How do I install the Besa Luma 18?

It is hardwired and installs directly to a standard 4" octagonal outlet box, centered on the fixture; 90°C supply wire is required for incandescent lamping. Besa’s installation guide is linked above, and we recommend a licensed electrician.
