Parking Photometric Study


In Part 1 of our blog, we discussed the necessity of photometric study in today’s world, particularly in meeting California’s diverse lighting needs. In Part 2, we will delve into the process of photometric study, shedding light on how it optimizes lighting solutions throughout the state.

The Process of Photometric Study:

Data Collection:

Photometric study begins with the collection of accurate and comprehensive data related to lighting conditions. This involves using specialized equipment such as light meters, luminance meters, and spectrophotometers to measure parameters like illuminance, luminance, and color temperature. In California, this data collection is crucial due to the varied lighting requirements across different regions.

Lighting Simulation:

Once the data is gathered, lighting professionals use advanced software tools to create simulations and models. These simulations help visualize how light will behave in specific environments, enabling designers to test different lighting configurations virtually. By adjusting factors like the position, intensity, and color of light sources, designers can optimize the lighting design to meet California’s unique requirements.

Analysis and Evaluation:

The collected data and simulations are then analyzed to evaluate the lighting performance. This analysis involves assessing factors such as uniformity, glare, and color rendering. Lighting professionals compare the obtained results against established lighting standards and regulations specific to California. Through this analysis, any shortcomings or areas for improvement in the lighting design can be identified and addressed.

Design Optimization:

Based on the analysis and evaluation, adjustments and optimizations are made to the lighting design. This may involve repositioning light fixtures, changing the type or color temperature of lamps, or implementing lighting control systems to achieve desired lighting levels and distribution. Design optimization ensures that the lighting solution aligns with California’s safety, energy efficiency, and aesthetic requirements.

Implementation and Monitoring:

After the design is finalized, the lighting solution is implemented in the designated area. This may involve installation of new lighting fixtures, retrofitting existing ones, or integrating smart lighting systems. Throughout this process, careful monitoring ensures that the implemented lighting solution meets the expected outcomes and complies with California’s lighting regulations.

Benefits of Photometric Study in California:

Accurate Lighting Solutions:

Photometric study enables precise lighting design tailored to California’s unique environment. By incorporating scientific measurements and simulations, lighting professionals can ensure that lighting solutions meet the specific needs of each location, resulting in optimal lighting performance.

Energy Efficiency:

Efficient use of energy is a key consideration in California. Through photometric study, lighting professionals can identify energy-efficient lighting fixtures and controls that reduce energy consumption while maintaining sufficient lighting levels. This helps California achieve its sustainability goals and minimize environmental impact.

Enhanced Safety and Security:

Photometric study plays a vital role in enhancing safety and security throughout California. By analyzing lighting conditions, glare, and uniformity, lighting professionals can design lighting systems that improve visibility and reduce the risk of accidents or criminal activities in public spaces, roadways, and pedestrian areas.

Aesthetically Pleasing Lighting:

California’s renowned landmarks and architectural marvels deserve lighting that enhances their beauty. Photometric study aids in designing lighting schemes that showcase the unique features of these structures, while considering aspects such as color rendering and light distribution. This ensures that California’s landmarks are visually appealing day and night.


Photometric study is an essential process for optimizing lighting solutions in California. By collecting accurate data, simulating lighting scenarios, analyzing results, and implementing optimized designs, photometric study enables lighting professionals to address the diverse lighting requirements of the state. Through this scientific approach, California can achieve efficient, safe, and visually appealing lighting that enhances the lives of its residents and preserves its natural beauty.
