Photometric Performance—Traditional sports lighting systems use metal halide lamps with large bulb jackets and mogul base sockets located in the axial center-line of the optical. This lamp design impedes optical efficiency by producing inefficient symmetrical light distributions with too much light in the upper beam. Some upper beam light is lost in the sky and grandstands or, in the worst case, can be the source of light trespass and glare.

The Ultra★Sport floodlight, on the other hand, utilizes an advanced double-ended metal halide lamp without a bulb jacket and a new unique reflector design.

The elimination of the outer bulb allows placement of the lamp arc into the focal point of shallow parabolic reflector forms needed to build high center beam candle power and provide the highest beam efficiency possible with wide beam distributions.

This new lamp/reflector configuration produces a more efficient, oval light distribution with very tight vertical light control to minimize wasted light and maximize light on the playing field.

Glare/Spill Light Control—The Ultra★Sport floodlight’s precise optical design limits the amount of vertical spill and light pollution without the use of external visor/louver assemblies that increase wind loading and structure costs. Optional internal cutoff skirts are available and provide direct cutoff of the arc tube at 15 degrees above the floodlight’s center aiming point for optimum glare control without the high losses normally associated with external glare reducing devices.

Photometric Choices—Different combinations of primary and secondary reflectors, in conjunction with the new double-ended lamp, provide multiple oval light distributions.
