Yes - I have converted a lot of bulbs in my 4 games to LED's.
I am a BIG Led Fan - but NOT for Gi.


I have NOT done a WHOLE game in LED's but I have done a lot of the coloured inserts.
Like EB, I have done most of Fish Tales - looks GREAT.
Funhouse I used LED's selectively and I feel looks bloody good, same with WH20 - in both these games I also ADDED some extra blue LEDs around the place for a blue 'glow effect'.

CFTBL - used sparingly and selectively under inserts.

I have tried , experimented and used LED's in GI sections on NONE of my games - I dont like it at all for Gi ( except for ONE spot on the FH machine where the incandescent was doing my right eye in - LOL).

The complexity of trying to answer "what bulbs do I use where / what styles "  -  is too hard to answer, I had the same question myself at the beginning and ended up guessing my way through it all with 3 or 4 seperate Cointaker orders over a period of months in order to get the games 'right'.

As one example  - I have found that where a yellow might look disastrous on one game , it looks quite good on another, this example can be repeated with colours, insert sizes on all my games and THATS why I had to order and order and keep 'knocking colours out' before I was eventually happy.

If you own any of the titles I own , I am more than happy to raise the hood and write a list of what I did.
