Outdoor LED lighting such as commercial LED flood lights provide some excellent benefits for exterior areas requiring illumination because of how they GENERATE light and how they DISTRIBUTE light. So basically you trade a longer life for a poorer quality light, in regards to visual perspective with HPS.īenefits of LED Flood Lights What are the benefits of outdoor LED flood lights? If you are using high pressure sodium you may see longer “useful” life as these lamps see less lumen degradation than metal halide, but their fuel structure produces a very “orange” light with a very low color rendering index. For example, if you are using metal halide lamps, you may see light that is “whiter,” but these types of lamps tend to have accelerated lumen degradation, meaning the light output of the lamps decrease quickly after initial install, and as a result the overall lifetime of the lamp decreases (we have all seen those flood light fixtures that have “pink” lamps that are barely providing any illumination on the ground). Lighting Performanceĭepending on the type of HID lamp your facility utilizes, the performance characteristics of your flood lighting can vary significantly. It can easily cost up to $1,200 in labor and material to maintain a single exterior flood light fixture over the course of three years. These are expenses that can really add up over the course of a few years. Many buildings and facilities do not own a bucket truck or lift and as a result have to hire an outside contractor to maintain these fixtures. In addition to the potential lamp lifetime concerns, flood lighting, being commonly mounted at heights above 15 feet, often requires the use of a bucket truck or lift to change out a lamp or a ballast. Maintenance costs are often a big concern for outdoor lighting applications such as HID flood light fixtures. A 400w or 1000w HID fixture (very common wattages for exterior flood light fixtures) can cost up to $209 and $525 to operate per lamp, per year, in electricity costs alone. The function of the area being illuminated, combined with the quantity, spacing, and mounting height of the poles and fixtures plays a role in the existing wattages that are utilized. The higher the wattage the higher the light output. Common Issues What are some common issues with HID flood lighting applications?Īll HID lamps have some inherent characteristics that can lead to issues for those managing the exterior lighting applications.Ĭommon (HID) lamp wattages used for commercial and industrial flood light fixtures range from 100 watts to 1000 watts.
