What kind of bulb does the Ellison Pendant Large take?

The listing does not specify a bulb type or wattage. Check the fixture's socket and rating before buying bulbs, and choose a bulb that fits under the opal glass diffuser.

Dimmability depends on the bulb and the wall switch you use. A dimmable bulb paired with a compatible dimmer lets you lower the soft glow for evening use.

How large a room does it suit?

The wide shade is meant to anchor a room, so it works best over a dining table, kitchen island or in a tall entry. In a small room it can overwhelm the space.

Can it be hung on a sloped ceiling?

The material does not state sloped-ceiling compatibility. The elongated chain links suggest some hang adjustment, but confirm with the manufacturer before installing on a slope.

Does the opal glass diffuser come included?

Yes. The pendant is described with a softly rounded opal glass diffuser as part of the fixture, so the glass shade is included with the pendant.

How does it compare with a plain dome pendant?

It offers the same broad dome form but adds a dimensional knuckle and elongated chain links for more architectural detail. A plain dome is simpler and usually less expensive in look.
