Thanks to Eric for this monster of a room heater..! It took two or three attempts to start from our Variac for some reason, but it seems stable enough now.

I have the uncoated version of this lamp (same R bulb though), that's quite a beast. I really like its design and construction, it's very nicely assembled and I can't imagine how much labor went into its production. There's no way this would be economically viable today...

Indeed. The metalwork of the top support is quite something..!

It's unbelievable how much effort was involved in making that part.

It's unbelievable how much effort was involved in making the whole lamp! That is a super quality item (much better than mine Razz ) What's the light like visually? With clear merc directly out the front and corrected merc reflected out from behind it must have an odd green tinge to it

@Ria - You're welcome! Yep, definitely a room heater!
@Max - That's why I find collecting these old lamps so appealing...the modern world is only about profits, with no pride.
@AgentHalogen_87 - The color comes in two phases...blue-white (5500K) off center, and /DX (4000K) directly underneath.
