the zoo reduce energy use with indoor lighting retrofits. The new targets were the outdoor poles at the
guest entrance that illuminated trees, walkways, and
two famous bronze gorilla statues. The existing architectural poles were attractive, so the zoo wanted to

flexible enough to accommodate the different poles,
but at the same time deliver great light."
It turned out there was only one product that fit
the application: LEDioc from EYE Lighting International, Mentor, OH. The LEDioc was designed for
fast field retrofit of post-top luminaires, and preserves
the optics and photometric performance of the existing luminaire. The zoo's legacy light sources were
250-W metal-halide and 250-W mercury-vapor lamps,
so the 37-W LEDioc represented an 85% reduction in
energy use. Newell notes that zoo employees at first

LEDioc lamps looks brighter and more vibrant, and

make everything better in our second hundred years;
the new site lighting is a part of that."
"The zoo plans to continue to improve lighting
throughout the complex, and I look forward to working with EYE again," Edward Newell concluded. CA
