Thank you for this so much-well done too of course!!

It’s good to see you still have some metal halide (at least that’s what I presumed it was). Pulse start is more efficient than the old probe start, and the PSMH doesn’t seem to shift color temperature as much as the old probe start lamps. I don’t think we have any of the PL-L roadway fixtures in the US, but they are still popular in 2’ X 2’ recessed parabolic fixtures in indoor fixtures in commercial businesses. From what I had heard about them, they are a terrible light source when used in commercial indoor applications, because they get hot and can sometimes melt the lampholders in fixtures. When I was doing lighting retrofits on 2- foot X 2-foot, 9-cell parabolic fixtures for indoor applications, I would replace any PL-L or U-bent lamps with three F17T8 lamps, so the lamps were centered between the three rows of parabolic cells.

0:51 ahh these used to be everywhere where I live in England, but got changed to horrible leds unfortunately.

7:50 this lamp looks like less used, I didn't see big blackening above electrodes

Nice video!

I hope in some Councils go to the LED retro fit lamps rather than swap all the lanterns in years to come i wonder? The 100w HPS fitting (globe type) in the UK this is a Urbis Saturn.

The street light fixtures you think ate unknouwn maybe is a Selux Urbi or maybe is a Super Saturn made by Schréder GIE group

that indal 2500 had a very old lamp in there it must have been good quality then

Die Schréder Saturnus armatuur lijkt me een rot ding om een lamp in te vervangen.

4:45 I love indal arcs

Why not cleaning the luminaire glasses?

7:21 Whats the name of the song?
