Best Fulham ballast for 90W SOX lamps? « on: August 16, 2022, 11:37:39 PM » Author: 70HPS
Hello everyone, is there a Fulham ballast I can use for 90W SOX lamps? I have a Philips bulb but don't have the gear to run it.

I like HID, CFLs and incandescents :hps: :cflhd: :a19incan:

Favorite indoor light source: PL Fluorescent (Preferably preheat, maybe rapid start, maybe instant start but instant start is boring)
Favorite outdoor light source: High Pressure Sodium (MV maybe, but HPS is relaxing)

The best ballast in terms of Fulham ballasts are Fulham Workhorse 5 ballasts.

If you want the correct ballast for your 90w SOX low pressure sodium lamp, here is one for sale:

https://www.ebay.com/itm/144635969047

If you want to go the cheap magnetic ballast route like I did, I used a 70w M98 pulse start metal halide ballast with the original ignitor swapped out with an imported Philips SX76 2 wire parallel ignitor.

I used a WH-5 with 3 of the 4 red leads connected to the lamp. The last red lead is capped off.
