While browsing Mexican ballast catalogs, I have noticed that in ISB Sola Basic's catalog, they actually manufacture magnetic ballasts that are designed for operating Philips' CPO-TW CosmoWhite ceramic metal halide lamps. I find it strange to know that magnetic ballasts designed for Philips' CPO-TW CosmoWhite lamps actually do exist because most of us know that they usually use electronic ballasts. ISB Sola Basic makes them for 60w, 90w, and 140w CosmoWhite lamps.
You can find these ballasts listed on page 118 of the following catalog:
