This type of lighting is generally used to provide illumination to areas for vehicle and pedestrian use. There is a wide range of fixture sizes, shapes, and mounting types that can be categorized as lighting for parking garages or canopies.
Below are a few image examples of Canopy and Parking Garage Light Fixtures
Common (HID) Lamp wattages used for Parking Garage lighting and canopy lighting fixtures range from 100 Watts to 400 Watts. The higher the wattage the higher the light output. The function of the area being illuminated, combined with the quantity, spacing, and mounting height of the fixtures plays a role in the existing wattages that are utilized. A 175w or 250w HID Fixture (very common wattages for Garage Lighting) can cost up to $109 and $156 to operate per lamp, per year, in electricity alone.
Maintenance costs are often a big concern for Parking Garage Light Fixtures and Canopy Light Fixtures. In additional to the potential lamp lifetime concerns, Parking Garage lighting and canopy lighting, being commonly mounted over parked vehicles, can be difficult to access and maintain during normal business hours. A standard size parking garage utilizing HID Lamp can easily spend up to $32,671 in maintenance costs over the course of 3 years.
Depending on the type of HID Lamp your facility utilizes, the performance characteristics of your Garage Lighting and Canopy Lighting can vary significantly. 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 Parking Garage Lights that have “pink” lamps that are barely providing any lighting on the ground). If you are using High Pressure Sodium you may see longer “useful” life as these lamps see less lumen degradation then Metal Halide, but their fuel structure produces a very “Orange” light with a very low Color Rendering Index. So basically you trade a longer life for a poorer quality light, in regards to visual perspective.
Garage LED Lighting and LED Canopy Lights provide some excellent benefits for Parking Garage applications because of how they generate light and how they distribute light. Light Emitting Diodes generate light via a semi-conductor, as opposed to the consumption of a “fuel source” like in HID lamps. In regards to “distributing” light, LED fixtures commonly utilize “Multi-Point” sources, meaning the fixtures have Multiple Diodes with individual optics. When you compare this to the way most HID fixtures distributor light (with a single bulb and reflectors within the fixture), the result is light that is more EVENLY “distributed’ across a surface.
Common wattages for Garage LED Lighting often range from 33 Watts to 100 Watts, often resulting in a 40%-60% reduction in energy consumption. The reason for this can be referenced to the “GENERATION” comments above, and can result in savings of up $75 per fixture per year in electricity costs.
