Default Re: Crompton 60W bulb

Darkroom lamps where made of red glass obviating any chance of a white light leak. Very under run to prolong life and no need for any blue light anyway, just as well they as where not cheap. Somewhere I have one I got second hand in 1970...72 when I got it for my teenage darkroom. Then I discovered the sodium street lights did a better job (at night) and for no cost!
