@@homeguestunton Certainly love the strangeness of running these coated metal halide lamps in an outdoor residential security light fixture specifically intended for mercury vapor lamps. Turns out to be a nice way to improve CRI and lumen output. Had to use a European low voltage Philips SI51 ignitor to assist with reliable lamp ignition. I just love how the mercury vapor yardblaster security light looks with having the 3200K coated probe start metal halide lamp installed with its warm glow. I also love the strangeness of running these probe start metal halide lamps on low power factor HX autotransformer ballasts as well since these lamps are generally intended for use on CWA ballasts since most ballasts that I have seen that were specifically designed for probe start metal halide lamps tend to be CWA ballasts instead of HX autotransformer ballasts.
@@kenytha5 As far as I know, the 175W M137/M152 pulse start metal halide lamps run at roughly 130V and 1.5A much like 175W M57 probe start metal halide lamps and 175W H39 mercury vapor lamps do, but 150W M102 pulse start metal halide lamps along with the uncommon 150W S56 high pressure sodium lamps run at roughly 100V and 1.8A. In that case, you can use a 175W M137/M152 pulse start metal halide lamp on a 175W H39 mercury vapor ballast if you use a European superimposed ignitor and hook it up to the ballast. If you search for “tanning bed ignitor” on eBay, you should be able to find European superimposed ignitors pretty easily. Although the 150W M102 pulse start metal halide lamps and 175W M137/M152 pulse start metal halide lamps have similar electrical characteristics, they are not exactly interchangeable with each other, but you should be able to safely run a 175W M137/M152 pulse start metal halide lamp just fine on a 150W M102 pulse start metal halide HX autotransformer ballast since the higher arc voltage drop of the 175W lamp would lower its operating current on the 150W M102 pulse start metal halide HX autotransformer ballast close to its ideal specifications, but not really the other way around from what I can tell.
The lamp inside is a 3200K base up burn coated 175W M57 probe start metal halide lamp for the North American market.
These coated lamps were mainly used in indoor commercial applications, and I mainly saw them back in the day, they aren’t as common anymore

Question: Is the current between M102 and M137/52 the same? Are they interchangeable?

You have many 175w mercury lamps, they have a nice green color but monochromatic and annoying to the eyes
