Cleveland, O. - To conserve war-needed aluminum, the Westinghouse Lighting Division is using mirror-glass reflectors in yard lights for war plants. The substitution releases aluminum for war uses at the rate of 180,000 pounds a year and at the same time produces a light that projects 10 per cent more illumination. A workman is shown here assembling one of the new lights.
