Advanced Metal Halide Lamp— The Ultra
★ ★ ★ ★ ★Sport floodlight
takes advantage of metal halide lamp technology, proven by
decades of use in all types of lighting applications. It uses an
advanced generation of lamps specifically designed for use in
sports lighting. Offered in a choice of 2000, 1500 or 1000 watts,
these white light sources feature a double-ended design without
an outer bulb, and provide an average rated life of 3000, 6000
and 10,000 hours, respectively. A standard mogul-base 1500W
metal halide lamp has an average rated life of 3000 hours.
These advanced lamps also provide excellent color rendering
with a 4000 degree Kelvin color temperature.
New Optical Design— A two-piece reflector configuration is
utilized featuring a Rear/Primary reflector and a Front/
Secondary reflector.
The Rear/Primary reflector is made of press-molded glass
featuring a special high reflectance coating for a mirror like
finish and 95% visible light reflectivity. The Front/Secondary
reflector is spun from high quality specular aluminum and has a
GE patented ALGLAS
® finish.
This new lamp/reflector configuration produces a more
efficient and effective oval light distribution with very tight
vertical light control to minimize wasted light and maximize light
on the playing field.
