in my town they are using post top lanterns in the newer neighborhoods for residential street lighting and Westinghouse / Eaton Vanguard ballast in arm fixtures are common for rural yard / driveway lighting
there is a house near me that has a 35/55 watt SOX street light fixture mounted post top facing sideways to light up there 1980's "architectural" home

I would say Honda as well. My elderly neighbor has an old Honda string trimmer from 1995 that had been sitting in her garage for over 10 years. When I went to start it up, it still somewhat ran. Replaced the carburetor, and now it works like the day it did from day 1.

Our Toro walk-behind lawn mower has a Tecumseh engine in it.  Never gave us any problems despite that its oil had never been changed in its 15 years until a few months ago.

I'm just curious about which brand of gas-powered yard equipment, such as blowers, string trimmers, chainsaws, walk-behind lawn mowers, etc. Stihl used to be my favorite, but about five years ago, their quality went downhill very fast. Now, it's a tie between either Honda or Maruyama. I just finished replacing the carburetor in my neighbor's Honda string trimmer from 1995. It still starts on the first or second pull and runs like new. I've never used Maruyama equipment, but from what it sounds like, their quality is second to none and they still manufacture everything in Japan. I've heard Echo/Shindaiwa is excellent as well.

I just remembered another house I went to one time. It was out in the country, set pretty far off the road. It had some more of those commercial type post type fixtures, in black. These were on tall poles though, about what height you’d see for a utility installation, whereas a lot of the HID post top-in-residential installs I see put them at a lower height.

I just looked up the place on Streetview, and these weren’t GE Town and Country, they look more like Cooper Traditionaire models.

The place didn’t look very old, I’d say late 2000s era or so, so probably HPS units.

Worked on the restoration of a Westinghouse Silverliner 250W/S50 OV15...

The latest edition of “Inside Lighting Infoletter” web site  has an in depth article entitled” Investigating The Purple Light
Phenomenon In LED Street Lights”. Interesting conclusions.

Check ebay regularly, and also the web finds board here on LG. Low wattage MV appears from time to time for very good prices, most of mine have been from ebay.

If you live in a 230v country, one option you have is to import a 12v pure sine wave inverter that does 120v and run it off either a deep cycle battery or a strong 12v power supply and you'll be able to run the North American lamps and gear which might be more common to find online.

Rommie does this I believe. This works best if you intend to have your lamp set up as a demonstration and of course only attempt if you can do so safely.

For 40/50 watt mv, a 39w magnetic mh ballast works a treat with ignitor removed.

pure guess but to sound like - related to one of the other companies

he name is derived from osmium and Wolfram (German for tungsten, also used in English). Both elements were commonly used for lighting filaments at the time the company was founded.

per Wikipedia

for me it is less of a "country" and more of certain items from countries / regions
like eastern European lanterns and LOW wattage mercury from Japan

I would assume heat as well. Incandescent lamps never had a problem in enclosed fixtures since they are the ones that create heat lol. CFLs and LEDs usually have those warnings on the packages because they have electronics in them that will fail faster due to more more heat build up depending on the orientation of the lamp and what type of light it's used in.
