1. What is the Lighting Calculation?

The lighting calculation estimates the total wattage needed for a space based on its area and the required watts per square foot. This helps in planning proper illumination for various settings.

2. How Does the Calculator Work?

The calculator uses the lighting equation:

\[ \text{Total watts} = \text{Area} \times \text{Watts per sq ft} \]

Where:

Explanation: The equation provides a basic calculation for determining lighting requirements in a given space.

3. Importance of Lighting Calculation

Details: Proper lighting calculation ensures adequate illumination for tasks, enhances safety, and helps in energy-efficient design.

4. Using the Calculator

Tips: Enter area in square feet and required watts per square foot. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical watts per sq ft value?
A: It varies by space type: offices 1-2W/sq ft, retail 3-5W/sq ft, kitchens 4-6W/sq ft.

Q2: Does this account for LED efficiency?
A: No, this is a basic calculation. For LEDs, you may need fewer watts for equivalent brightness.

Q3: Should I include natural light?
A: This calculates total artificial lighting needs. Natural light can reduce requirements.

Q4: Are there standards for lighting levels?
A: Yes, organizations like IESNA provide recommended light levels for different spaces.

Q5: How does ceiling height affect this?
A: Higher ceilings may require more powerful fixtures, which isn't accounted for in this basic calculation.
