W tube lit for the first time.
I'm sure many of you remember this W tube fitting and pair of tubes that was given to me end of 2016, since that day I had never really lit the fitting until a few days ago. Of course it being so old was naturally a  concern, it dates to 1968. More importantly, was the Quickstart setup going to be too harsh for such a fragile lamp? It was a risk I had to take.

Thankfully it struck up first time and ran very quietly, suggesting its had next to no use in the time its been around. The W tube seemed unfazed by the quickstart ballast, no blackening was observed on the cathodes. Overall its an incredibly bright fitting, its easily as bright as a regular 4' T12 tube.

Love this thing! Dunno what it's supposed to be and I don't think it knows what it's supposed to be but whatever it is it's terrifying and it never gets boring. Wonder how many of these 2D-BC-T12-things there are? Are those BC ends? What is it?

Its basically the very first version of what we know today as the GX53 pizza CFL lamp. It was designed to be a compact fluorescent lamp, rated at 40w they certainly achieved it, but the fragility and expense of them (they were handmade) would have probably played a part in why they weren't so popular.

Fascinating light this is!

This is a legendary piece of fluorescent lighting history, it must be looked after incredibly carefully! Makes the 25w Philips W tube I have seem like a Genie CFL in comparison. Cool Cool

Nice to see this lit, it's an absolultely fascinating tube and fitting

Its in a corner where no one really goes, out the way on purpose so its completely safe. I want so bad to restore the fitting, but I can't bring myself to leave such a rare and fragile lamp floating round in the meantime.

Excellent to see this lit, does it work on a standard F40T12 ballast or is the voltage higher? It seems strange that they went to the effort of making parallel tubes with bridged connections, instead of the simple U-shaped curves as used earlier on the Philips TL-W of 1964. And I wonder which of these companies was first with the flat fluorescent lamp.

I'm unsure of the specs of the tube, I've ahd the tube 3 years and only dared fire it up recently.

They might have had trouble with the glass cracking on so many bends, hence the joins?
