Frequently Asked Questions

Can I use outdoor ceiling lights where there's no roof or covering?

No. Outdoor ceiling lights must be mounted to an overhead structure. For fully exposed areas, you must choose a wet location rated fixture, but installation must still adhere to local code regarding mounting structure.

What is the difference between an outdoor flush mount light and a semi-flush mount?

An outdoor flush mount light sits directly against the ceiling, making it ideal for low-clearance areas like carports. A semi-flush fixture hangs slightly down (6–18 inches), adding a more decorative element for medium-height ceilings.

What are the best applications for an outdoor flush mount light?

An outdoor flush mount light is perfect for low-clearance areas like carports, storage sheds, entryways, or covered patios where maximum headroom is needed. They provide uniform, widespread light without drawing attention.

Should my porch ceiling lights be damp or wet rated?

Porch ceiling lights under a deep roof or awning usually only require a damp rating. If the fixture is exposed to wind-blown rain, or is used in a shower/steam area (like a spa enclosure), it must be wet location rated.

How do I choose the right size outdoor ceiling light for my space?

For covered areas, you can approximate the needed diameter of the outdoor ceiling light fixture by dividing the width of the space (in feet) by 1.5. For example, a 10-foot wide porch needs a light roughly 7 inches in diameter.
