The Recessed Can Calculator is a handy tool used to determine the number of recessed cans needed to adequately light up a room or space. It takes into account factors such as the total area to be illuminated, the coverage area per can, and a spacing factor to ensure even distribution of light. By inputting these variables into the calculator, users can quickly and accurately determine the optimal number of recessed cans required for their lighting needs.
Formula of Recessed Can Calculator
The formula used by the Recessed Can Calculator is as follows:
Number of cans = (Area to be illuminated / Coverage area per can) * (1 + Spacing factor)
Where:
- Area to be illuminate is the total area of the room or space you want to light up.
- Coverage area per can is the effective coverage area of one recess can. This can vary depending on the type and wattage of the light fixture. It's typically provided by the manufacturer and can be in square feet or square meters.
- Spacing factor is a multiplier to account for the spacing between the recessed cans. This can vary based on personal preference, lighting design standards, and the layout of the space. A common spacing factor is 1.1 or 1.2, meaning you add 10% to 20% more cans to ensure even coverage.
General Terms Table
| Room Type | Desired Lighting Level | Typical Spacing Factor |
|---|---|---|
| Living Room | Moderate | 1.1 - 1.2 |
| Kitchen | Task Lighting & Ambient | 1.0 - 1.5 |
| Bathroom | Bright & Task Lighting | 1.0 - 1.2 |
| Bedroom | Moderate & Accent Lighting | 1.2 - 1.5 |
Example of Recessed Can Calculator
Let's say we have a room with an area to be illuminate of 50 square meters. Each recessed can has a coverage area of 5 square meters, and we're using a spacing factor of 1.2.
Number of cans = (50 / 5) * (1 + 1.2) = (10) * (2.2) = 22
So, we would need 22 recessed cans to adequately light up the room.
Most Common FAQs
Measure the length and width of the room or space, and then multiply the two dimensions together to get the total area.
The coverage area per can refers to how much space one recessed can effectively lights up. It can vary depending on factors like the type and wattage of the light fixture.
The spacing factor is a multiplier that accounts for the spacing between recessed cans. It helps ensure even distribution of light throughout the room.
Yes, you can use the calculator with measurements in either square feet or square meters. Just make sure to use consistent units for all inputs.
