Most round wagon-wheel chandeliers use a candelabra-style E12 base. At least one model in these listings uses a standard medium Edison E27 base, so check the product spec before buying bulbs.
Listings show compatibility with LED, Edison-style, halogen, CFL, and incandescent bulbs. Many specifically call out Edison-style bulbs, and several note compatibility with LED/CFL/halogen options.
Several chandeliers are described as dimmable. They work with dimmable bulbs and require a compatible dimmer switch to provide adjustable brightness across the full dimming range—confirm the listing specifies “dimmable” and use a matching dimmer type.
The listings describe compatibility with flat, sloped/angled, and vaulted ceilings. Many models can be mounted horizontally or vertically; check the product spec for any model-specific mounting limits.
Brightness is reported in different ways: one listing shows about 800 lumens per bulb (based on a bulb spec), while a multi-bulb wagon-wheel example cites a combined output of 3,600+ lumens for larger configurations. Check individual listings for exact lumen totals.
