Frequently Asked Questions

What should I consider when choosing recessed lights?

When selecting recessed lights, consider the height of your ceiling and the size of your room. Smaller fixtures, like 4-inch and 5-inch models, are perfect for task lighting in kitchens, while 6-inch fixtures are commonly used for general lighting. Larger sizes, such as 8-inch and 10-inch, are ideal for creating a broad wash of light.

What is the difference between can lights and canless recessed lights?

Can lights are traditional recessed fixtures with a housing can installed above the ceiling. Canless recessed lights are a newer, slimmer option that doesn't require a housing. Canless lights are typically LED, more energy-efficient, and easier to install, especially in tight spaces.

What are the benefits of LED recessed lighting?

LED recessed lights offer significant benefits like 1) Energy efficiency: Use up to 75% less energy than incandescent bulbs; 2) Long lifespan: Can last 25,000+ hours; 3) Low heat output: Safer and doesn't affect room temperature; 4) Dimmable options: Many LED recessed lights are compatible with dimmer switches.

Can recessed lights be installed in an existing ceiling?

Yes, recessed lights can be retrofitted into existing ceilings. Canless LED options are especially suitable for retrofit projects due to their slim profile and easy installation. However, access to the area above the ceiling (attic or crawl space) may be necessary for wiring.

Are recessed lights energy-efficient?

Yes, especially LED recessed lights. They consume less energy than traditional bulbs and can significantly reduce your electricity bills. Look for ENERGY STAR certified fixtures for maximum efficiency.
