There are many different types of lighting available on the market. For lighting areas that have special requirements, it is important to choose the right option to prevent future issues from occurring. A good example of one of these areas is freezer lighting applications. Specialized lighting is needed to meet the unique needs of a freezer, whether it is a small unit in a convenience store or part of a much larger line of units grouped together to create one long stretch of freezers. Below are a few suggestions for choosing the right freezer lighting applications for your location.
Freezer units can be one of the biggest energy draws in a location, especially for supermarkets or large-scale operations. In fact, most grocery stores have an energy bill where over half of the annual cost of operations is directly related to freezer and refrigeration units alone. We recommend implementing a lighting solution that will provide you with the best lumen output per watt of energy consumed for the best overall value.
There was a time when fluorescent was once the standard for this area of lighting thanks to their improved efficiency per watt over older options. However, the new trend is to choose LED for freezer lighting applications. One of the main reasons fluorescents are no longer a viable option for this type of lighting is because they are not designed to handle extreme temperatures well. In fact, most fluorescents lose up to 25% of their lighting output in frigid temperatures. LED lights are better at handling the cold without losing lumen output, which makes them the better investment.
All freezers are not necessarily the units you see at the grocery store in the frozen food section. Freezer lighting can also be part of a much larger freezer found in the backhouse area of restaurants, grocery stores, and other cold storage units. When it comes to this area of lighting, you need to invest in lighting that comes equipped with a cage to protect your bulb. This comes in handy when receiving and organizing deliveries by reducing the risk of accidentally hitting the bulb if a delivery is stacked too high. Using a protective cage design will help to avoid this concern altogether.
Make sure lighting is UL listed for wet locations, since most freezers typically have condensation and vapors that will take a toll on lighting solutions. It is also a good idea to choose lighting that is completely sealed or well-gasketed to avoid internal failures. We recommend using vapor tight options to prevent any issues when it comes to this type of lighting.
You should also consider the use of sensors, which will shut the lights off when the door is not open helping to save you money on lighting costs. A good rule of thumb is to install multiple sensors per unit to ensure you get the most savings.
