When it comes to energy efficiency, lighting is especially important when people are looking to reduce their electricity costs. Additionally, smart lighting technologies offer improved energy efficiency that allows for automated and dimmed lighting options. By understanding the different types of lighting and their applications, you can create an ideal lighting environment for any space.
