NUVO Lighting 60-7179 Sommerset, 9 Light, Chandelier Fixture, Brushed Nickel Finish with Clear Glass

No bulbs are included. It takes nine E26 medium base lamps, A19 shape, rated to 60W each on 120V. Any standard A19 medium base lamp works, so you can put in LED A19s at the same base and shape to cut the load from a potential 540W down to a fraction of it.

No. It is rated for dry locations and indoor use only, so it cannot go on a covered porch, in a shower or tub zone, or anywhere exposed to damp air. For an exterior or bathroom-wet application you need a fixture listed damp or wet. Indoors it is cULus listed on 120V.

The Sommerset weighs 12.76 lbs, which is within the 50 lb limit of a listed fixture-rated outlet box. A plain non-fixture-rated box or a box mounted only to drywall is not acceptable; use an outlet box or brace rated to support a luminaire. It mounts by rod to the ceiling and ships with 12 feet of supply wire, so you have slack for a sloped or high mount.

Dimming depends entirely on the lamp you install, not the fixture. The Sommerset is a line-voltage incandescent-technology fixture with no onboard driver, so a standard A19 incandescent on a compatible dimmer will dim. If you install LED A19 lamps, you need lamps marked dimmable and a dimmer rated for LED loads. The fixture has no selectable color temperature.

Yes. The fixture is listed with a CA Prop 65 chemical disclosure for lead. That matters for institutional and government procurement in California, where the warning has to be passed through on submittals and product documentation.
