M137 vs M57 « on: October 20, 2019, 12:37:19 PM » Author: HomeBrewLamps
Is there any possibility that I can run 175 watt probe start lamps on an M137 ballast without the ignitor?

I have done it with my M250R2 since I don't have pulse start lamps and it seems to work fine. I have heard that they have lower OCV than probe start ballasts though and so the might not start reliably.

It almost seems like the lamp is running dimmer than usual..

Quote from: Metal Halide Boy on October 22, 2019, 07:47:09 AM It probably is. M57 lamps run at 285-320 volts, M137 lamps run at 240-290 volts. I didn't realize that! Thankyou for the info. Time to ditch this M137 ballast.
