+1 this. I tried putting in some regular ole' Ablaze 1's (pretty sure they were Ablaze 1's...need to triple check) and they ghost like CRAZY on my SF2. I had heard there were issues and went with it anyways thinking it wouldn't annoy me. I was wrong. Grand Master's Challenge's initial light show loses a lot of its impact when everything is slightly glowing.

I used the LEDs only under the inserts and tried cool white under whites, red under red and oranges under orange. Cool white looked nice. Red was only a slight improvement. Orange was actually worse than a regular bulb and was actually more difficult to see. If someone has a suggestion for orange, I'm all ears.

You also need to go with a non-polarized style bulb, as the first/last bulb in a chain on the circuit board mounted bulbs will not light. You can fix this issue by reversing the polarity of the socket...but why go through that trouble when there are non-polarized bulbs that will address that issue?

When I decide to re-do my original attempt at LEDs on my SF2, I'm definitely only running with LED's under the inserts. I'd like to try a color changer under the Grand Master's Challenge light and the Bracelet Target...but IIRC the Bracelet Target flashes (haven't turned mine on in a while). I'm not sure if that will be an issue (anyone?).

I'd stick to regular bulbs for GI and playfield illumination, but that's me. 2 CENTS

Nice! A dedicated Z-Back at that. People toss SF2 in all kinds of whacky cabinets, so when a pinball person says, "I have a SF2 vid"...I typically expect to see a hacked up Defender monstrosity.

Also, nice before/after. Funny thing about my SF2 Pin's backglass is that I actually cover it with up with pinball event flyers and misc. stuff.

I'm a bit of a SF fanatic, which is partially what lead me into pinball (after years of collecting vids, I bought a SF2 pinball just for the theme and was hooked ).

ANYWAYS! Color changing down there might wind up looking cool actually. I didn't think about that. I was originally thinking about getting some regular colored bulbs and sort of randomly placing a purple here...a green there...so it looked more like there was different stuff going on in the windows in the alley than just one bright white light. *shrug*

It was for this:

Just my recommendation: only do the under playfield inserts. I've yet to see an led setup that handled playfield illumination well. Also on sf2, try warm white for orange inserts. Orange led on mine looked really weird and barely lit.

Yeah. Definitely anti-flow design, but that's partially what makes it unique. You're either gonna love that about it...or hate it.

The regular multiball mode in this game is interesting (and very exploitable). I like how you need to control and move your jackpot shots around in a strategic way, so your last high earning jackpot is on a shot you can easily make/repeat. It's not easy, but once you get it down you can crack your first 1B game utilizing that strategy.
