This is a beautiful high quality indoor fan. The blade assembly allows for a quick and simple installation or removal for cleaning due to its twist and lock mechanism. It comes with one st19 filament led bulb 4.5w at 2700k. It has a standard e26 base so it easy to replace or change the bulb type. I put this up in a 12X16 room and the air flow is excellent. Classy and elegant! Highly recommended!
