LEDized Highmasts

LEDized Highmasts

These poles used to have Holophane HMST 1kW HPS lights on them. I'm guessing the MTO came with in the past year or so and changed them out to LED. Interestingly the poles on the other side of the overpass still had the original Holophane HMST lights.

I haven't really been following LED fixture makes and models so I'm not sure what's the make and model of these.

One interchange near me got LED with these same lights but Caltrans left most of the other ones with their cool MH and HPS (both light sources used on the same pole) setups alone. I really need to get a picture (or a streetview) of those before they get LEDisease.

Good quality things are awesome. Cheaply made things are not.

Hmm, over here the MTO has been comparatively slow in changing out existing installs to LED compared to the city owned lighting.

Interesting that they used MH and HPS on the same pole. Must have looked pretty neat at night. Over here I've only ever seen privately owned MH highmasts.

Caltrans still has some HPS lingering around and they haven't bothered to change them out yet (mostly underpass lights though).

They are also well maintained interestingly enough despite using LED to replace their streetlights (they haven't bothered using LED for the underpass and sign lights that much.)

I think underpass lights on the MTO highways are for the most part still HPS but I think I've seen one get spot replaced with a LED. Cooper or Holophane HPS wallpacks mounted to a 90 degree galvanized steel bracket were the usual way the MTO lit underpasses. These replaced the old Holophane MV wallpacks and 4/6ft PG17 fluorescents originally installed in the 60s.

I kinda wish MTO kept lighting signs, IMO even a LED sign light would be better than the current unlit signs.

Caltrans doesn't install underpass lights anymore except if they light a city road. Old ones were recessed into the ceiling with a flat glass (some had bowls) and they were MV. In the 80s or so they installed HPS lowbays and retrofitted some of the old ones but by the 1990s, it seems like they stopped caring about maintaining most of them.

Even Caltrans is phasing out sign lights. They tried LED ones but some districts just removed them completely.

Yeah the recessed into the ceiling underpass lights Caltrans uses looks a lot cleaner than the hanging wallpacks commonly used here. Too bad they don't really maintain them anymore.

BTW, here's a shot of the old MV sign lights that MTO used. They were 125w MV.
