LED Retrofit for Exterior Canopy Lights

Accurate Technologies Helps Education Facility With LED Lighting

Accurate Technologies recently assisted Pasco Hernando State College, in upgrading the exterior hallway lighting for an complex of aging classroom buildings. In the process, we also had the opportunity to make recommendations on suitable replacement products for various areas around several campuses. The goals of the college included greater energy efficiency, more reliability and less maintenance with their equipment, and better quality of lighting. Since buildings had been added to their properties over several decades, there was a wide variation in existing light fixtures, types of lamps and even the color of the ‘white’ light from various light sources.

The decision was made that a consistent color standard of 4000K was to be implemented across all of their facilities. 4000K color temperature is a popular decision among commercial facility managers, since it provides a neutral balance between efficient light output and a comfortable warmth.

We provided LED retrofit modules for this facility's canopy lights. 30w modules replaced 100w Metal Halide lamps. The picture was taken after the bottom floor was retrofitted, but the top floor still had the original lamps.

We provided LED retrofit modules for this facility’s canopy lights. 30w modules replaced 100w Metal Halide lamps. The picture was taken after the bottom floor was retrofitted, but the top floor still had the original lamps. It’s apparent that the lower floor is much brighter, yet energy use is reduced by 70%.

As the project progressed, comparisons and tests were implemented between Accurate’s retrofit products and other technologies, particularly induction lighting. Tests were conducted and LED emerged as the best solution. Our AT-DML-E26-30W Directional Retrofit Module was chosen over 40w and 80w induction lamps.

At one area of PHSC’s main campus, there’s a cluster of two story buildings linked by exterior walkways, built in the 1970s. These walkways were originally lit with 70W mercury vapor HID lamps, and later upgraded to metal halide. Most were 100w, but there were a few 70w lamps mixed in, and even the odd high pressure sodium lamp here and there. The installation crew started with the bottom floor of the complex, removing the existing ballasts and wiring each socket directly to the incoming 277v lighting circuit. Then the 30w LED modules were installed.
Once the bottom floor was complete, the facility manager inspected the results and took these pictures.

The amazing thing about these pictures is that the ‘before’ and ‘after’ conditions are visible in the same photographs. There are no camera tricks here, this is the difference that a well planned LED retrofit can make. This project resulted in a 70% power reduction, an 80% heat reduction, lower maintenance costs and much higher quality and quantity of light.

Accurate Technologies also provided LED solutions for classroom areas, interior hallways, gymnasiums, stairwells, warehouses, libraries and auditoriums.

There are no dark corners or unsafe areas in this open courtyard. Our LED Retrofit modules increased visibility and safety, yet reduced energy use by 70%.
