How much light you get from an outdoor chandelier depends on the amount of lighting you want. That said, an outdoor chandelier is decorative in nature. It is typically meant to be less bright than its security-oriented counterparts such as floodlights and motion sensor lights.
The light from a light bulb is measured in lumens which indicates the bulb’s brightness and the intensity of light emitted. A standard 40-watt bulb generates more than 400 lumens of light. The more the wattage, the higher the lumens.
For an outdoor chandelier, it is recommended that you use bulbs with an intensity of anywhere between 100 and 400 lumens. Anything greater than 400 lumens may be overkill.
