I think one idea might be to use a 70W M98 pulse start metal halide HX ballast to run a pair of 35W S76 high pressure sodium lamps in series. Or another idea is to import lamps, ballasts, and fixtures from abroad if you can save up for them. I often do that to help me from not getting bored.

You could run both of them in series, but I would recommend reducing the capacitor value to ensure they run properly. You would need to get a clamp meter to ensure that they are running at the proper 3.25A they require.

An individual lamp is 3.25A and each lamp is half the arc voltage drop (135V) of a 1000W M47 probe start metal halide lamp (270V). When a pair of 400W M59 probe start metal halide lamps are wired as a series pair, the arc voltage drops of both lamps sum up together at roughly 270V.

Quote from: stillaintjeff24 on November 29, 2025, 10:55:46 PM I have that ballast! Just got it today* but no 35 watt High pressure sodium lamps. Too bad! I need to get some more diverse lamps.  I have a few 35w HPS . I'll never use them .  If you pay shipping , I'll send them to you .
