A new floodlight designed for the night lighting of baseball fields, ski slopes, skating rinks and similar areas, is pictured undergoing tests on an indoor range at the General Electric Illuminating Laboratory at Schenectady,N.Y.

Instruments to measure the output of the 1,500-watt enclosed lamp may be seen at the end of the tunnel-like range 150 feet away.

Huge curtains with openings 10 feet in diameter are spaced at irregular intervals to prevent reflected light from reaching the measuring instruments.

These curtains produce the corkscrew tunnel effect seen in the picture.
