Both have their universal ballasts installed. The one on the left is the dimmer one. Its actually running slightly better than the first test. The right fixture runs fine. Not as noisy as before. Strange that they appear on different phases on camera. These are running stable and not flickery

Could it be that the previous owner use of LED T8 directly on these ballasts caused some small temporary issues? Ill give them a good run and see how they improve

EOL lamp test:

When EOL lamp is placed into the left fixture on the blue wire, both bulbs light up 1/3 brightness and flicker at 30 or 60hz continuously and may light up fully anyway after some time.
When the SAME lamps are placed in the right fixture, keeping the EOL lamp on the blue socket, they barely light up at all.



Date code on the bad ballast is E 81 and L 80 on the good one

Very, very good comparison, especially since these are the same brand ballasts and both HPF.
If the left fixture lights up fully, with 120hertz flicker instead of 60hertz, I'd be surprised.
But regardless, I'm pretty sure when the capacitor goes bad, it pretty much becomes a low power factor R.S ballast.
This makes me wonder if this same event can happen with magnetic PL-L HPF R.S ballasts, and also magnetic HO and VHO ballasts as well.

The left does come on with the 120hz but dimmer lol.

As seen in the next photo. I tried an EOL bulb in it, the EOL lamps rectified at 60hz sometimes lighting up fully for a few seconds. when I put the same EOL lamp in the good fixture they didnt really light up much or do anything. I'll keep both ballasts and I'll still use the defective one if there is no danger from its bad cap.

I think the use of LED tubes by previous owner is what killed it

I wouldn't keep using the bad cap ballast for long. But aye, I know nothing at all when it comes to this kind of
situation. Thankfully, I've never had a magnetic ballast with a cap this bad.
I'm willing to bet LED killed it as well though... the Thermo-matic X ballasts are typically some of the most reliable ballasts
you can get lol

The good cap one seems off on the kill a watt readings, 0.99 PF and almost 100 watts?

I think the bad cap should be fine to use, but definitely not with F34s lol
