When we were kids this was the COOLEST light ever. The Tensor. Even if it was the preferred illumination by the Middle-Aged Nebbish.
The story's true, by the way. From his 2007 obit: "Jay Monroe, an engineer whose wife’s discontent over the strong light he needed for bedtime reading provoked him to invent a high-intensity, low-voltage minilamp whose use spread to desks, jewelers’ worktables, limousines and far beyond, died on June 12 at his home in Sands Point, N.Y. He was 80."
Shot himself. Also: "His marriage to his first wife, the former Barbara Schultz, who had been annoyed by his nocturnal reading habits, ended in divorce."
Criminey, I wish I hadn't googled that.
