An old picture and the 250w one has since been traded away. The 175w one I still have casts a pleasant greenish glow when lit. Made in '65 and it has a /C phosphor.
And you saw the clear Radiant 250w merc that I rescued from the electrical program at my school, and you remember it from like some 25-30 odd years ago!
These bulbs take me back. First saw them 7 years ago on Silverliner's old site, right when I was getting back into lighting. Found them looking for info on greened out mercury lamps and a Norelco bulb I found at work.
Why did they stop making the /C Phosphors?
