Frequently Asked Questions
What is the golden rule for recessed lighting spacing?
A reliable guideline is to divide your ceiling height by 2. For an 8-foot ceiling, space fixtures roughly 4 feet apart. For a 10-foot ceiling, space fixtures 5 feet apart. Keep fixtures spaced approximately 2.5 to 3 feet away from walls to prevent unwanted shadow pooling.
What is the difference between 4-inch and 6-inch recessed pot lights?
4-inch lights provide sleek, modern, focused architectural lighting ideal for modern homes and task zones. 6-inch fixtures have a broader beam angle and higher lumen output, making them popular for general room illumination with fewer total ceiling cuts.
What color temperature (Kelvin) is best for recessed LED lights?
2700K (Warm White) creates a cozy ambiance for bedrooms and living rooms. 3000K (Soft White) is the most popular modern whole-home standard. 4000K (Cool Neutral) is excellent for kitchens, bathrooms, and garages.
Why are canless wafer LED lights replacing traditional recessed cans?
Ultra-thin canless LED wafer lights are less than 1/2-inch thick and clip directly into drywall. They do not require bulky metal housing cans and can be installed directly underneath joists, pipes, and ductwork.
