Last Westinghouse OV-20 mercury street light in my area

Even though it's more than 20 miles away in Ruston, Washington....I was amazed to see this was still there AND it had been relamped! It is 400w mercury vapour on a small, dead-end residential street!

Nice to see this still in use and maintained, the only OV 20s here are the ones in parking lots, I'm pretty sure my area is completely HPS.

Odd to have such a high wattage light on a dead end street. 100 or 175w MV seems good enough.

You would think so True but i've seen both sides of this scenerio in more than one place.

Example 1. a small Town in east texas. Chandler uses 100 watt HPS for all it's roads. even the Biggest arterial road which passes right through it. most of these 100 Watt lights are Nema heads and small cobraheads but a Few of these 100 Watt Lights are bigger fixtures normally meant to carry 250-400 watt lamps oddly enough. there's Two 400Watt MV GE M400R3's on the far south side of this small town for whatever reason.

in my Hometown of tyler seemingly random stretches of residental streets have 200 and 250 Watt HPS streetlights where as most of the residental streetlights are 100 watts

Here most residential areas are lit with 50W HPS with more-urban/thickly settled neighborhoods lit with 100W HPS. The northern part of the state had a different electric company that used 70W HPS instead of 50W an they used a lot of 70W HPS up there. 250W HPS is used widespread across the state too but not much 400W HPS except for the freeways (which are now all LED here).

Here, most residential streets used to use 70-100w HPS. Back in the MV days, 100, 125 and 175w was common. I'm not sure what they use now since a lot of the LED fixtures they use in residential don't have NEMA tags.

The LED wattages all vary too much lol. HID was much more consistent lol. In Cranston they use 20, 40, 70, and 133W LED for 50, 100, 250, and 400W HPS. A little too conservative with the LED wattages IMO. RIDOT uses 133W LED for 250W HPS and 280W LED for 400W HPS, which actually works out great. RIDOT's freeways are very well lit with those wattages (provided there are no missing poles, wiring faults, or dud fixtures). I think RIDOT's long-term plan is to use the individual nodes to dim the lights in times of low traffic.

Providence opted to use 42W LED to replace 50 and 100W HPS and 139W LED to replace 250W and 400W HPS. West Warwick opted for 42W, 53W, and 139W LED. Unsure why they use 42 and 53W since they're so close. They're Cree fixtures. The 42W ones are the tennis racket ones and the 53W ones are the nicer looking version that looks like a mini version of the 139W ones. I don't know the Cree model numbers...

Arlington Texas has some LED Highmast fixtures. I wonder what wattage those are cause they light the ground as well as the 1000 watt sodium fixtures they replaxed.
