I have one of these NOS wall mount lawn glos. Need to make a custom stand for it. Also only place i managed to find these in service is a laundromat in Cassopolis MI but they are incandescent
To find such 150w H39/S63 HPS lamps, I would recommend getting an Eye Super Ace retrofit lamp or the Sylvania Unalux retrofit lamp. Those can operate in that fixture since it uses an H39 ballast with no capacitor.
The only thing that really matters is that the ballast is a lag type HX (high reactance) autotransformer ballast if you want to run Sylvania Unalux lamps. Although HX autotransformer mercury vapor ballasts usually do not use capacitors, you can sometimes find them using capacitors, but they would only be wired in parallel with the mains input and only serve as power factor correction. The ballasts that you never want to use the Unalux lamps on are the CWA (constant wattage autotransformer) type ballasts, which instead use a capacitor in series with the lamp. As a matter of fact, I do have a rare high power factor HX autotransformer ballast specifically designed for 400W H33 mercury vapor lamps, but it has a parallel capacitor integrated inside the casing. In that case, if you want to use a high power factor ballast that can run the Unalux lamps, you will want to look for ballasts that specifically have the capacitor wired in parallel with the input terminals rather than a capacitor in series with the lamp. You can still safely run the Unalux lamps on low power factor HX autotransformer ballasts, which have no capacitors at all in the circuit like what you see with this particular fixture. You can also run these same retrofit lamps pretty safely even on ordinary 175W H39 mercury vapor yardblaster luminaires and NEMA head luminaires since they almost always have HX autotransformer ballasts in them. Additionally, it is also good to know that the Iwasaki Sunlux Super Ace and Ultra Ace high pressure sodium retrofit lamps in particular are also designed to safely operate on CWA ballasts with series capacitors in addition to HX autotransformer ballasts.
Additionally, did you know that in North America, 1000W mercury vapor lamps were available in 2 separate types that are NOT interchangeable with each other? First, there are the common 1000W H36 mercury vapor lamps, which operate at a high arc voltage drop and a low operating current. Secondly, there are the less common 1000W H34 mercury vapor lamps, which operate at a low arc voltage drop and a high operating current. Interchanging 1000W H36 and 1000W H34 mercury vapor lamps is NEVER a good idea because doing so could cause lamps and ballasts to be destroyed. While the 1000W H36 mercury vapor lamps and ballasts are easy to find, you will need to be extremely patient if you are searching for 1000W H34 mercury vapor lamps and ballasts because they are extremely hard to find. It is actually true that you CAN run the 1000W H36 mercury vapor lamps on 1000W M47 probe start metal halide ballasts due to the fact that 1000W M47 probe start metal halide lamps have very similar electrical properties compared to 1000W H36 mercury vapor lamps despite the difference in arc tube size, but on the other hand, you CANNOT run the 1000W H34 mercury vapor lamps on 1000W M47 probe start metal halide ballasts due to the significant difference in electrical characteristics between 1000W H34 mercury vapor lamps and 1000W H36 mercury vapor lamps, plus some 1000W M47 probe start metal halide ballasts also have 1000W H36 mercury vapor lamps listed together as well.

Looks beautiful

So cool!

Who made the flicker flame bulb with the holes in it?!
