Oh, (...). Good luck finding one.

Yeah I have, we’ve been in touch quite a bit for other parts. I have a shipment en route from him right now actually.

I asked about a mi36 bowl and he unfortunately doesn’t have any. The last one he had was cracked, so I didn’t want it.

Try messaging Phil from eBay.

howdy folks, i've been eyeing the Qianshun/Glow Object offerings as a backup plan for my SOX lamps, to keep on hand should my existing Advance ballasts fail, and just out of curiosity to compare them to more traditional SOX equipment. i haven't been able to track down any of the Philips-brand Electronic SOX ballasts and these are the only other electronic offering i could find.

i looked at all the listings and pictures, and all the ballasts say 220-240V operation, so if i do end up getting one i'll need to track down a step-up transformer. no big deal, Digi-Key and Mouser have reputable hard-wire ones that won't break the bank.

all that being said, anyone have any experience running these ballasts on any of their SOX lamps? what do you think and how do they hold up to a regular old magnetic ballast? any input is appreciated and thanks in advance for sharing!

Looking for a bowl that would fit a 55w Philips MI36 lantern.  If it has the latches still attached that’s a nice bonus, but not a requirement. Need it to fix a fixture I have with a busted bowl.

If anyone over in the UK might have a spare or two, please get in touch! I am located in Canada, and will obviously pay for shipping and whatnot. Yes, I’m aware it will be expensive.

Thank you!

happy Independence Day, all US ccollectors!

My thought exactly

Ahh. I didn't noticed this. But usually when referring to emission of an element into the IR, I used to referring to spectral lines there, like in the case of Xenon in Short-arc xenon lamps, or Thorium halide, which also have spectral lines in the IR as well.
And I didn't noticed that I wrote "Spectroscope" in my former comment. Will correct this.
But there is another disadvantage that I don't know why it exist: Why short-arc indium lamps have very short life?
And the fact that the spectrometer needs to be calibrated, makes it hard to use, as if I would buy one of the cheap Aliexpress spectrometers that connects to the smartphones or to the computer, I don't know how to calibrate them.

HP320 is a spectrometer not spectroscope, as it outputs a *calibrated* spectrum and this differentiates it from DVD based toys.

No, Dy / or Dy based rare-earth mixes radiate more selective at visible wavelengths, and this among other things makes them more efficient in MH lamps for general lighting. Here is an example.

The reduction of heating current after starting with trigger start is mentioned in Waymouth’s Sylvania book, Zwikker and Elenbaas’ Philips FL book, and older versions of the IES lighting handbook.  I will put together some scans for you.0
