The Hubbell Outdoor Lighting Ratio: Ensuring Proper Illumination for Outdoor Spaces

Proper lighting plays a crucial role in creating safe, functional, and aesthetically pleasing outdoor spaces. The Hubbell Outdoor Lighting Ratio (LOR) is a valuable tool for determining the appropriate amount of light needed for specific outdoor areas.

The LOR is expressed as a percentage and represents the amount of light that is emitted downwards from a luminaire. A higher LOR indicates more downward-directed light, while a lower LOR indicates more light emitted in other directions.

Factors Influencing LOR Selection

The choice of LOR for outdoor lighting depends on several factors, including:

Purpose of the space: Different areas may require varying levels of illumination. For example, pathways and driveways need sufficient light for safety, while patios and decks may prioritize ambiance.
Presence of obstructions: Obstacles like trees or walls can block light, necessitating higher LORs to ensure adequate illumination.
Surrounding environment: Light pollution concerns or the presence of sensitive wildlife may call for lower LORs to minimize glare and disturbance.

LOR Guidelines for Common Outdoor Areas

Here are some general LOR recommendations for common outdoor areas:

Pathways and driveways: 60-80%
Patios and decks: 40-60%
Stairways: 60-80%
Entrances and security areas: 80-100%

Benefits of Using the Hubbell LOR

Utilizing the Hubbell LOR offers several advantages:

Optimal lighting levels: LOR ensures appropriate illumination for specific tasks and activities.
Reduced energy consumption: By optimizing lighting distribution, LOR minimizes wasted light and lowers energy bills.
Enhanced aesthetics: Proper LOR creates visually appealing outdoor spaces without excessive glare or light pollution.

Conclusion

The Hubbell Outdoor Lighting Ratio is an indispensable tool for designing effective and efficient outdoor lighting systems. By considering the purpose, obstructions, and environment of the space, lighting professionals can select the appropriate LOR to ensure safe, functional, and aesthetically pleasing outdoor spaces.
