Alumag Belmag HATO-R

Alumag Belmag HATO-R

Just testing the Hato-R streetlight fixture after restoration. I got it 2011 with HPS 70W ballast and ignitor installed. This setup was changed some decades ago by the utility company. Now I just cleaned the lantern and replaced the gear back to MV 250W as it was built for originally.
The reflector became shiny again with very few corrosion after decades of use.

Wow! Very interesting lantern. It looks like a bat. This is something really special.

Not very happy with the current mess on this site.

That's quite an unusual luminaire, Michael! This reminds me of early LPS and HPM luminaires of the 1930s... I never knew that such intricate design was used after the 1950s.

I think that the design of this reflector might be more recent for modern MV lamps. I wouldn't be surpriced that the shape and light distibution was calculated on early computers back then in these days. I’m trying to figure out patents and the date of invention for this entire fixture but it's not that easy I think.

Nope. I think that this reflector shape was being calculated with the very first CAD computers from that time at some universities here around.

Was it a popular lantern? I don't think so. Cannot remember I saw it in Switzerland

I saw them a lot but only in the canton Bern. There were several main roads lit by these around Bern and Thun but also in the Jura mountains around Tramelan. Most of them have been replaced in the last couple of years by Saphirre 2, Iridiums and now LED lanterns.
