This document summarizes different types of light fixtures and reflectors. It introduces fixtures as electrical devices that create artificial light using electric lamps. Common fixture types include chandeliers, ceiling lights, and wall sconces. Reflectors are specialized surfaces that redirect light, and the best reflectors are shiny and opaque so that no light passes through. Types of reflectors are also classified as good, poor, or mediocre based on how much light they allow to pass through.
