What can be the best incandescent ballast for a 125w 220V MV?

FB is toxic, full of ads and BS "knowledge", while forums are molstly friendly and ads free. I don't really understand why FB instead of LG.  Sad

Alright, I'm sure there are HPS bulbs that work for it because I've seen them. However I severely doubted the existence of a compatible SOX bulb for it, I was just checking if there might have been one.

There ARE HPS retrofits for MV. See here .

Hobbies come and go.

If someone leaves this site because his hobbies have shifted somewhere else, that is perfectly fine to me.
But if someone start ignoring this LG just because "on FB it is more convenient" (or something similar), that would be very sad.

@Xmaslightguy, yep that's what I'm thinking. Very unfortunate, but true.

The crazy thing is I've bought a few ballasts from this seller for really good prices including free shipping ! I figured they'd know better ! Roll Eyes

The White House is more than likely completely LED right now.
Wouldn't surprize me if that's the case...
But there's probably lots of nice vintage lights in there that should never have anything other than incandescent in them.

I love how the seller calls it a LED in the description ! Huh? Roll Eyes
Yep, just clueless.

This fixture is made by Curtis Lighting in Chicago. This one is called a "forty-sixty". The ad is from the IES handbook published in 1947.

@mobilite , I have a pair of louvered that look very close to those in your book except mine are made by electrolier

I typed up this post the other day, but my PC rebooted so now I have to start over (thanks antiquated forum system).
Anyway, I recently moved to a new area and there is this nice park nearby. It was built in 2011/2012 and has hundreds of landscape lights, as well path/step lights. I assumed they were 70w MH, but turns out they are actually 18w CFLs. I did some research on those plug in g24d-2 lamps, which use a magnetic ballet. A bit surprised it wasnít an electric ballast based on the installation year.

Unfortunately, only about 10-20% of the fixtures are still functional. Same are tagged with black electrical tape, presumably to indicate a needed ballast replacement. The park is maintained by a volunteer group, and I contacted them offering to volunteer to repair the lights, but sadly never heard back. I was looking forward to it. ☹

The lights are 277VAC, and made by BEGA lighting. I looked up their current catalogue, and same/similar versions of the different fixture designs are still made, but in LED only versions. I put some thought into retrofitting the existing fixtures. I donít think drop-in retrofit lamps would be good, because we are still relying on the existing/failing ballasts. I donít think ballast bypass would be safe, because then there is 277VAC exposed at the lamp socket if the outer glass of the fixture gets broken (which has already happened to a few), exposing line voltage to weather and people in the park. Line voltage should remain contained to the ballast compartment.

I was tracking to find an LED waffle lamp that could be mounted flat in place of the existing lamp socket, with an external 277VAC input driver for the ballast compartment, but my search came up short. Everything was far too powerful. I attached a few pictures, but they are not good quality.
