There are several factors that need to be considered when you’re talking about lighting design or installing a new light fixture, like electrical load requirements on your system, the number of watts that your current system or breaker can handle, properly connecting wires, and securing them. Not to mention how the fixture will look once it’s installed. For example, if you have a sloped ceiling, you’ll need to purchase specific fixtures that have bases that are sloped with the ceiling. All these things are taken into consideration when you work with a professional electrician.
