Hot, inefficient warehouse lighting is something many companies deal with every day but don’t put a lot of thought into. If a warehouse operates 24 hours per day, the lighting can be one of their biggest overhead expenses.
One solution to lower your energy costs, and HVAC costs, is to install LED lighting, and if possible, a lighting-control system. Earlier this year, Digital Lumens installed LED lighting with a control system in the United States Cold Storage Inc.’s Hazleton, PA warehouse. According to the case study, the old high-pressure sodium lamps consumed 465 watts each and were costing USCS $0.46 per square foot per year.
The new Digital Lumens Intelligent lighting consumes only 160 watts and only costs 3.5 cents per square foot per year, a decrease of 93% in energy costs! Also, with the new lighting, the warehouse was able to get rid of the chiller-load associated with the metal halide lighting and eliminated their lamp replacement and maintenance budget. USCS’s payback period for this project was just 14.6 months.
To contribute to the savings, Digital Lumens also implemented their LightRules system which uses a combination of fixture-based sensors and a lighting control system to dim or turn off lighting in areas of the warehouse that see sporadic activity. With this system, the lights are only on 22.17% of the time. Having the lights on when no-one was around was wasting a lot of energy and contributing to maintenance expenses.
Using the intelligence of the Digital Lumens Light Rules system, combined with the efficiency of LED Lighting, United States Cold Storage was able to slash their lighting overhead expenses by over 90%.
