Nice to see a new HPS fixture being installed, especially in a CalTrans district!

I’ve always been interested in all kinds of lighting, mainly incandescent and HID, and especially all kinds of sodium lamps (HPS/LPS). I’ll tolerate LED but I’m not a fan of it.
I’m not proud to say that my city has Devolved to LED.

This is a older video from the 1990s. The Philips Ceramalux lamp that they installed in the light is from the 1990s.

Interesting to see a CalTrans style slip pole base too.

Over here MTO uses conventional poles but with frangible couplings to the pole base.

I find that it is interesting to see that the workers hung the lantern before the pole was fastened to the ground.

I apparently failed to notice the low resolution video!  :lol: Still, nice to see how CalTrans used to install and maintain HPS lights.

Looks like the M400A2 they installed on the arm was a 200 watt.

Somehow I didn't see that, my bad! Wonder why they swapped the 310w ballast door with a 200w one?

Energy savings . Convert 100 fixtures and you just saved 11,000 watts of electricity while the "average" driver will never notice the difference.

Makes sense! Though I've never seen 200w HPS lights in service on the freeways here (unless there were some I didn't know about). All I've seen is 310w. The only place I've seen the 200w lights were on overpasses.

Yeah, I used to question why you would want to go to the expense of swap ballasts and lamps to go to T8 to save 8 watts but when you have a large building with thousands of lamps in use that 8 watts becomes 16000 watts.

That’s weird, I’ve never seen 310w HPS on freeways! I was too late to see the freeways before CalTrans went LED. I have seen 310w HPS at an intersection before. I also saw 250w HPS on a freeway.
