need preheat ballast for 2 f40t12 « on: October 23, 2019, 08:14:16 PM » Author: Walter Knox
i just bought a vintage louvered light fixture, it takes 2 f40t12 bulbs, it has a uneversal therm-o-matic rapid start ballast in it and it replaced a preheat ballast, i know because it has holes for starters, i have some tombstones with starter sockets so that is no issue, i looked on ebay and could not find a preheat ballast for it, but did not know exactly what to look for, what should i look under?

im sorry, what do you mean by the number? if you are referring to a part number, the original ballast is gone.

The same seller also has the Universal 203 ballast (item 301768956081), which operates two lamps like the 205 in item 291541991525.  My impression always has been that the 205 is a better ballast considering it has a starting compensator, which should lead to faster starting and improved lamp life, at least on the "lead" side.  I have wondered if there's any other reason to choose one over the other besides that.

https://www.ebay.com/itm/NEW-UNIVERSAL-205-TC-P-BALLAST-2-40W-T12-Fluorescent-120V-NOS-New-Old-Stock-/383171636663?_trksid=p2349526.m4383.l10137.c10&nordt=true&rt=nc&orig_cvip=true  I was going to get this but I missed it and it hasn’t been relisted, you could message the seller and see if it’s still available.
