Outdoor LED lights, such as led post top lights, provide several advantages for illuminating sidewalks and pathways due to the manner in which they produce and distribute light. Different from HID lights, light emitting diodes create light using a semiconductor, as opposed to using a “fuel source.” In order to “distribute” light, LED lights often use “multi-point” sources, which consist of numerous diodes with separate lenses. When compared to how typical HID lights disperse light (with a single bulb and reflectors inside the fixture), this results in light that is more EVENLY “spread” across a given area.
Energy Savings
Common LED post top light wattages vary from 30 to 120 watts, often resulting in a 35%-80% decrease in energy use. This is due to the remarks made about GENERATION, and it may result in power cost savings of up to $800 per fixture each year.
Cost of Maintenance Reduction
Again, owing to the manner in which LEDs create light, their useful lives evolve quite differently. LED-generated light output decreases VERY SLOWLY over time, as opposed to ceasing to operate after a fuel supply has been considerably depleted. Consequently, the functional life (typically more than 100,000 hours) of an LED product may be substantially longer than that of an HID bulb, which greatly saves the expenses associated with servicing post top lights over a longer period of time.
Lighting Efficiency
In terms of how LED fixtures DISTRIBUTE light, LED post top lighting applications often give a highly EVENLY spread light pattern due to the multi-point architecture. This indicates that the variation in light levels over a given area will decrease as the distance from the pole or fixture increases. This is in contrast to HID lamps, which often produce a “bright spot” immediately below the bulb, with light levels diminishing dramatically as the distance from the pole rises. The LED conversion results in a more uniform foot-candle distribution as compared to HID. In addition to providing an equal dispersion of light, LEDs are available in a variety of color temperatures, providing a variety of possibilities for enhancing the visual experience of “brightness.”
