Buying Guide
- Location and rating: Choose weatherproof or damp-rated boxes for exterior or high-humidity spaces; select wet-rated luminaires for showers or covered outdoor areas.
- Box material: Metal boxes offer durability and grounding reliability; non-metallic boxes are lighter and can simplify installation in some ceiling materials.
- Installation type: New work boxes are easier to install before ceiling material; old-work boxes are preferable for retrofits.
- Electrical load: Verify fixture weight and electrical ratings align with the box’s capacity and mounting hardware; consider grounding provisions and compatibility with existing wiring.
- Lighting needs: For general lighting, consider low-profile or recessed options; for accent or task lighting, tilt-adjustable gimbals or color-temperature selectable LEDs provide versatility.
- Accessibility and maintenance: Prefer boxes and fixtures with accessible screws and plugs to facilitate future maintenance or fixture changes.
- Complementary aesthetics: Match box style and finish to surrounding hardware to maintain a cohesive look in kitchens, hallways, or bathrooms.
