how far apart should can lights be

The spacing of can lights, also known as recessed lights, depends on several factors, including the type of light, its wattage, and the desired level of illumination. Here are some general guidelines:

General Spacing Guidelines:

1. Low-voltage can lights (e.g., 3-4 inches in diameter): 12-18 inches on center (o.c.)
2. Standard can lights (e.g., 5-6 inches in diameter): 18-24 inches o.c.
3. High-wattage can lights (e.g., 7-8 inches in diameter): 24-36 inches o.c.

Task-Oriented Spacing:

1. Kitchen countertops: 12-18 inches o.c. to provide adequate task lighting.
2. Bathrooms: 12-18 inches o.c. to provide adequate lighting for grooming.
3. Hallways and corridors: 24-36 inches o.c. to provide ambient lighting.
4. Living areas: 24-36 inches o.c. to provide ambient lighting.

Additional Considerations:

1. Lumen output: Higher lumen output lights can be spaced farther apart.
2. Beam angle: Narrow beam angles (e.g., 30°) require closer spacing, while wider beam angles (e.g., 60°) can be spaced farther apart.
3. Ceiling height: Higher ceilings require more lights or closer spacing to achieve the same level of illumination.
4. Room layout: Consider the room’s layout and furniture placement when determining light spacing.

Remember, these are general guidelines. The specific spacing requirements for your project may vary depending on the manufacturer’s recommendations and local building codes. Always consult the manufacturer’s instructions and a licensed electrician if you’re unsure about the spacing of can lights.
