Recommended Foot Candles for Large Signs and Billboards

Understanding Foot Candles

A foot candle is a unit of illumination that measures the amount of light reaching a surface. It’s crucial to know the ideal foot candle level for your sign to ensure it’s bright enough to be seen clearly, but not so bright that it causes glare or becomes distracting.

Recommended Foot Candles for a 14 x 48ft Sign

For a large sign or billboard measuring 14 x 48 feet, the illumination should be carefully planned to balance brightness and energy efficiency. Here are some guidelines:

– General Recommendation: Large billboards typically require an average of 20-30 foot candles of illumination to ensure readability from a distance, even in low-light conditions.

– High-Traffic Areas: If your billboard is located on a busy highway or in a city with a lot of ambient light, you may need to increase the foot candles to 40-50 to compete with surrounding lights and maintain visibility.

– Rural or Low-Traffic Areas: In less illuminated areas, you can often get away with 10-20 foot candles, as there is less ambient light interference.

The goal is to ensure your sign is visible from its intended viewing distance without wasting energy or causing light pollution. Properly illuminated signs enhance legibility and ensure your message is effectively conveyed.

 

Importance of Photometric Analysis for Large Signs

What Is Photometric Analysis?

Photometric analysis is the scientific study of how light will be distributed across a given surface. It uses precise calculations to determine how light from a fixture spreads, ensuring even illumination over the entire sign or billboard area.

This analysis is crucial for large signs like a 14 x 48ft billboard to achieve optimal visibility while minimizing dark spots or areas that are overly bright.

 

Why Photometric Analysis Matters for Large Signs

1. Ensures Even Illumination: A photometric analysis can help you plan the placement and angle of your light fixtures to achieve uniform brightness across the entire sign. Uneven lighting can make parts of your message difficult to read, especially from a distance.
2. Prevents Light Pollution: By calculating the exact light distribution, you can avoid spilling light into unwanted areas, reducing glare and contributing to environmental protection.
3. Optimizes Energy Efficiency: Photometric studies allow you to use the right amount of light without wasting energy. This can result in significant cost savings, especially when using solar-powered sign lights.
4. Enhances Visibility and Readability: For a large sign or billboard, every square foot should be evenly lit to make text and graphics easy to read, regardless of the viewing angle or distance.

Key Factors in Photometric Analysis

When conducting a photometric analysis for a large billboard or sign, several factors come into play:

– Distance from the Viewer: The further the average viewer will be from your sign, the more powerful the lights will need to be.

– Height and Angle of Light Fixtures: Adjusting the height and angle ensures the light spreads evenly. Proper placement of **up lighting** or **down lighting** can significantly impact the overall effectiveness.

– Ambient Light Levels: If your sign is surrounded by other light sources (such as street lights or nearby businesses), you’ll need to account for this in your analysis.

– Material and Reflectivity: The surface of your sign can affect how light is absorbed or reflected. Photometric analysis considers this to ensure consistent illumination.

 

Tips for Conducting a Photometric Analysis
