Parking garage lighting is a term used to describe both outdoor lighting and indoor lighting that is commonly surface, pendant, or recessed mounted to a structure’s ceiling, soffit, or overhang. This type of lighting is generally used to provide illumination to areas for vehicle and pedestrian use. Traditional HID parking garage lights, while common, aren’t the most efficient solution for your facility. In today’s post we will look at three compelling reason to convert your lights from HID to LED.
Light emitting diode (LED) lights generate and distribute light differently than their HID counterparts. LED’s generate light via a semi-conductor as as opposed to the consumption of a “fuel source” like in HID lamps. Additionally, they distribute light using multiple diodes and individual optics versus a single bulb and reflectors within the fixture. The results of this technology is light that is more evenly distributed on the intended surface below, while consuming significantly less energy.
To examine the particulars around energy savings we need to look at the common wattages for HID lighting versus LED lighting. For a typical HID lamp the common wattage is between 70 to 400 watts. If we look at the same range for a comparable LED fixture the range is between 24 to 82 watts.
So we can see just by converting your traditional HID lamps to LED there will be a 40%-60% savings in energy consumption. From a cost perspective, a typical LED retrofit will save the building manager roughly $300 dollars per fixture per year in electricity costs alone. Depending on the size of your facility this can be a very significant cost savings.
Maintenance Cost Reduction
In addition to the massive costs savings from energy consumption, LED’s can also save you money by reducing maintenance costs. Due to the way LEDs generate light, the way they progress through their functional life is much different. Instead of ceasing to function properly once a fuel source is significantly reduced, LED generated light output degrades very slowly over time.
As a result the functional life (often in excess of 100,000 hours) of an LED product can be significantly longer than that of an HID Lamp. For example, by converting conventional 250w HID wall pack to a LED wall pack, a typical facility with exterior building lights can save up to $5,341 over the course of 3 years maintenance costs alone.
Finally, while energy savings, and maintenance cost savings are important, it’s imperative that the lighting performance not be compromised. This again is where LED stand above the competition. As a result of the multi-point design, LED wall-pack-lighting applications often provide very evenly distributed light. What this means is that light levels across a given surface will vary less between fixture mounting locations. Compared to HID fixtures, which often product a “bright spot” directly underneath the fixture with light levels decreasing drastically as the distance between fixtures increases.
The result, is a more even foot candle distribution from the LED conversion. In addition to the even distribution of light, LEDs are available in a range of CCT’s (Correlated Color Temperatures), and as a result provide a range of options to increase the visual perception of “brightness”.
In conclusion we can see that an LED retrofit would help reduce energy consumption, decrease the maintenance expense, while increasing the lighting performance.
