1. What is a Garage Light Layout Calculator?

Definition: This calculator determines the number of light fixtures needed to achieve proper illumination in a garage space.

Purpose: It helps homeowners and electricians plan lighting installations for optimal visibility and energy efficiency.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Number of Lights} = \frac{\text{FC} \times \text{Area}}{\text{Lumens\_per\_light}} \]

Where:

FC — Foot-candles (illuminance level required)
Area — Size of the garage in square feet
Lumens_per_light — Light output of each fixture

Explanation: The total required lumens (FC × Area) is divided by the lumens provided by each light fixture.

3. Importance of Proper Garage Lighting

Details: Adequate lighting ensures safety, improves functionality, and enhances visibility for various garage activities.

4. Using the Calculator

Tips: Enter the desired illuminance (default 50 fc for general garage use), garage area, and lumens per fixture (default 3000 lm for LED shop lights).

5. Frequently Asked Questions (FAQ)

Q1: What's a good FC level for a garage?
A: 50 fc for general use, 75-100 fc for detailed work areas, and 20-30 fc for storage areas.

Q2: How do I find my light fixture's lumens?
A: Check the product specifications - typical LED shop lights range from 2,000 to 5,000 lumens.

Q3: Why does the calculator round up?
A: You can't install a fraction of a light fixture, so we always round up to ensure adequate lighting.

Q4: Should I account for light loss over time?
A: Consider adding 10-20% more lights to compensate for lumen depreciation and dust accumulation.

Q5: How do I measure my garage area?
A: Multiply length by width in feet. For irregular shapes, divide into rectangles and sum the areas.
