The lamp in the third picture looks longer.

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.

It's just a slightly different camera position, I should really have used a tripod

I guess one never gets tired looking at the warming up phase of SOX

Pretty, please no more Chinese failure.

Nope
Just one reason we have to preserve these wonderful lamps

Looks amazing And at 167lm/w its very efficient, although the 91w SOX-E version is even better!

I actually quoted the figures from the Philips one that came with the lantern, couldn't find the Osram ones but thought they'd likely be similar. If I find any different I'll obviously correct the info.

Yes most seem to be similar.
The 131w SOX-E lamp (Economy version of the 180w) gets about 206lm/w!

Nice colorful picture!

Your mission - should you choose to accept it - is to save unique and rare HID lighting before it's all scrapped.

Picture 2 is interesting, you very rarely see cathode flare on a 135, more so on the smaller lamps? I once had a 35 that flared up on start, but the flare was quite long, going halfway down one leg of the tube, and taking out the fuse!!
It was something I was going to ask James about but never got round to it?

Yes, I noticed that, this was first ever ignition, not lit it again yet so will see what it does next time.
