1. What is the Shop Lighting Calculation?

The shop lighting calculation determines the required electrical power (in watts) needed to properly illuminate a commercial space based on its dimensions, desired light level (lux), and lighting efficiency.

2. How Does the Calculator Work?

The calculator uses the shop lighting formula:

\[ Lighting = \frac{Length \times Width \times Lux}{Efficiency} \]

Where:

\( Length \) — Shop length in meters
\( Width \) — Shop width in meters
\( Lux \) — Desired illumination level in lux
\( Efficiency \) — Lighting system efficiency in lumens per watt

Explanation: The calculation determines the total wattage needed by considering the area to be illuminated, the desired brightness level, and how efficiently your lighting converts electricity to light.

3. Importance of Proper Lighting Calculation

Details: Proper lighting is essential for creating a productive work environment, ensuring safety, and reducing energy costs. Under-lighting can cause eye strain and accidents, while over-lighting wastes energy.

4. Using the Calculator

Tips: Measure your shop dimensions accurately. Typical lux values range from 100-200 for general retail to 500+ for detailed work areas. LED efficiency typically ranges from 80-150 lumens/watt.

5. Frequently Asked Questions (FAQ)

Q1: What are typical lux values for different shop types?
A: Retail shops: 100-200 lux, workshops: 300-500 lux, jewelry stores: 500-1000 lux, warehouses: 100-300 lux.

Q2: How do I determine my lighting system's efficiency?
A: Check the product specifications for lumens/watt rating. Modern LEDs typically range from 80-150 lumens/watt.

Q3: Should I include windows in my calculation?
A: This calculator assumes artificial lighting only. For spaces with significant natural light, you may need less artificial lighting.

Q4: How does ceiling height affect lighting needs?
A: Higher ceilings may require more powerful lights or additional fixtures to achieve the same lux level at floor/work level.

Q5: Should I add a safety factor to the calculation?
A: It's common to add 10-20% to account for light loss from dirt accumulation and lumen depreciation over time.
