Understanding Recessed Downlights
Recessed downlights, also known as can lights or pot lights, are fixtures installed into a hollow opening in the ceiling. When installed, they appear to shine light from a hole in the ceiling, concentrating the light in a downward direction. These lights are popular for their sleek, unobtrusive design and their ability to provide focused lighting.
Benefits of Recessed Downlights
Recessed downlights offer several advantages, making them a popular choice for both residential and commercial lighting solutions.
Aesthetic Appeal
One of the primary benefits of recessed downlights is their aesthetic appeal.
