ITT Series 13 and Westinghouse OV-15 Lit Up!

Probably the only time these guys will be lit until I get my own house, as these are 240V. Both are 175W MV. Shown lit with /DX Philips lamps from the 90s. They're used but still bright. The one in the Westy is a little more blue than the one on the left. Might be because the phosphor coating is wearing off on the lamp in the Westy. The ITT is from 1977 and I think the Westinghouse is from 1976. Both came from Sterling, Massachusetts.
