Enhancing the Lighting System at Cerritos Towne Center

Submitted by Associate Member Altech Electronics

The Opportunity 

Cerritos Towne Center is a premier shopping center located in the heart of Cerritos, Calif. With over 480,000 ft² of land, this Towne Center is home to notable tenants such as Walmart, Best Buy, Kohl’s, HomeGoods, and Islands Restaurant. The center was in need of a reliable LED Lighting upgrade to continue providing a dynamic and safe shopping experience. 

The Objective 

With an objective to improve the safety and sustainability of the property, the customer had a specific request to maintain an average of 2-4-foot candle (FC) readings across the entire Towne Center’s parking lot. In addition to improving light uniformity, the client was also looking to reduce glare and light trespass onto neighboring residential areas. To provide a suitable solution that will enhance the overall shopping experience, Altech Electronics conducted a complimentary photometric study of the project’s location.   

The Solution 
As a result of the objectives the customer provided, Altech Electronics recommended approximately 150 units of our 150W LED Area Light Hyper Series (ALHS), instead of our 90-120W LED Area Light that would have sufficed for a 400W MH replacement.  

The rated L70 150,000 hours lifespan and superior lumen efficacy of our lights (165 LPW) provided a significant improvement in both the sustainability and performance of the exterior parking lot lighting system. 

The Benefits 

Although we trust the integrity of our IES files and photometric software (AGI32), we took it a step further to verify the actual FC readings on site. As seen in the images, we projected FC calculations of 10.9 and 14.3 at two separate points in the parking lot; the actual meter readings on site were measured at 10.3 and 16.5 respectively. The difference between the photometric study projection and field light levels were minimal. 

Due to the significant reduction in wattage-used from retrofitting to energy-efficient LED fixtures, Cerritos Towne Center will realize over $20,000 in annual savings on their lighting utility costs and enjoy an ROI in 2.7 years.  

End Results  

In summary, through our detailed photometric study, Altech Electronics recommended our 150W LED Area Light Hyper Series (ALHS) as the best solution for the customers' FC challenges. Thus, the total system wattage reduced was over 40,000W. Furthermore, we were able to validate the accuracy of our photometric tools by comparing actual to projected light levels.  

In conclusion, Cerritos Towne Center was extremely satisfied with the overall solution Altech Electronics provided, which exceeded their expectations for the sustainability of the property, light performance levels, and the safety of their tenants and shoppers.
