Early lamp, even though it's pretty non descript compared to position restricted GEs and sapphire arc tube Westys of the era.

Cool lamp!

Not as old, but years ago, I found a Philips Westinghouse Ceramalux 250w at the old farm store where this came from. Pondered buying it but didn't. Wish I had. Was in the area last summer, and tried to go back to that store, but couldn't catch them open, and it almost looked like they were out of business.

Nice! I got a few Sylvania 70W BT25s with this style package and a red "lumalux" package.

To resist is to piss in the wind, anyone who does will end up smelling.
