LED Retrofitting of Post Top Lighting

These LED post top retrofit lamps, maintain the look and feel of traditional fixtures  found in pedestrian walkway lighting, street lighting in college campuses, historic districts, parks and recreational facilities, or residential streets, while lowering costs, and increasing energy efficiency. These Post Top Retrofit Kits are designed to be applied in very diverse set of outdoor lighting applications. These MH/ HPS replacement kits are engineered for fixtures that ranges from acorn globe style fixtures, to highly ornamental pole lights. Complete retrofit kits are available to upgrade pole lighting that include the post top fitter, decorative globe, and LED retrofit lamp.

These decorative pole retrofit kits offer numerous choices in upgrading luminaires, by replacing high wattage incandescent, high pressure sodium (HPS) or metal halide (MH) lamps in post top lighting applications with energy efficient LEDs at much lower energy use. Metro LED Lighting’s economic analysis has shown these replacement LED kits have high return on investment, fast paybacks, and no maintenance costs. By changing out inefficient existing lamps / fixtures, rapid paybacks are achieved in these decorative pole lighting applications.

Retrofitting Post Top Lighting - LED Benefits

Post Top lighting retrofitted with LED Fixtures or lamps can maintain the aesthetic and design elements of decorative pole luminaires. A wide variety of color temperatures (CCT) are available in the LED retrofits that can be configured for a warm incandescent feel (3,000K) or a bright white MH lamp look and feel (5,000K). By virtue of being DLC listed, light pollution is minimized, less light is wasted upwards, and Dark Sky Standards can be met. The LED sources use advanced optics, and reflectors for high quality lighting by providing better horizontal and vertical foot candles, improving visual acuity and pedestrian safety. These LED Post Top fixtures benefits include:

  • Ability to meet IES illumination standards while maintaining the design integrity of the decorative pole lights in the community
  • Improvement to the quality of the light, with less light waste, light trespass, providing more effective lighting, and higher energy efficiency, consuming often 70% less energy, thus having a direct impact on the kilowatt hours used.
  • Decorative pole lighting efficiency can be improved, putting more light on surfaces for visual uniformity, and acuity, while using less energy
  • Wide variety of choices of color temperatures (CCT), and much higher Color Rendering Indexes (CRI) than traditional HPS fixtures to improve the nighttime appearance of campuses, pedestrian walkways, or historic districts
  • These LED Post Top fixtures have much higher CRI values than HPS lamps, and selected LED Lamps often have CRIs which can exceed 80
  • Energy Savings are readily achievable by retrofitting Post Top Lighting often greater than 70% savings by replacing HPS lamps or MH lamps
  • Lower maintenance costs of MH and HPS post top lighting, by eliminating the need for periodic replacement of ballast, and lamps. LED post top lamps have luminaire efficiencies that are much higher than traditional HPS or MH fixture, lowering electric costs while raising efficacy. 
  • The LED lamps used in retrofitting these Post Top Lights have very long L70 lifetimes, often over 100,000 hours. Traditional light loss factors are thus minimized, with very long times for lumen depreciation, or virtually no dirt accumulation that often effects tradition MH or HPS lamps in post top lighting.
