Calculate

Number of Recessed Cans (RC):

A recessed can calculator helps in planning the right number of recessed lights for a room. Proper lighting enhances functionality and aesthetics, making it a crucial step in interior design and electrical work.

Formula
The formula to calculate the number of recessed cans is:
RC = (A / S) × (L / S)
Where:

• RC is the number of recessed cans.
• A is the room area.
• S is the spacing between lights.
• L is the length of the room.

How to Use

1. Enter the total room area (A).
2. Specify the spacing between lights (S).
3. Input the length of the room (L).
4. Click "Calculate" to find the number of recessed cans.
5. The result will appear in the provided field.

Example
Suppose the room area is 200 sq. ft, the spacing is 8 ft, and the room length is 20 ft. Using the formula:
RC = (200 / 8) × (20 / 8)
RC = 25
You would need 25 recessed cans.
