From an electrical point of view, there are two types of outdoor lights, including 120-volt AC and 12-volt DC lights. The first type has the same voltage as appliances in the house do, so the light can connect directly to an outlet. As for the second type, users have to use a voltage converter to connect it to the outlet. However, 12-volt DC lights are safer against electrical shock.
In terms of design, there are many types of exterior lights including path lights, wall and ceiling lights, post lighting, and deck lighting.
It is a good idea to install path lights on both sides of the driveway, near the sidewalk or near the pathway to the entry door. Some of these lights are solar-powered, so owners don't have to turn them on when they need to use them. Wall lights and ceiling lights can add extra light to a porch and add an aesthetic quality. There are many styles of these lights available.
Post lighting can create a romantic atmosphere. It is a good idea to install post lighting around a patio or a pool. It also serves well for lighting pathways or driveways, as they are more powerful than path lights. Deck lighting is useful for illuminating stairs, which makes them safer at night.
