Quoted from gweempose:
Mine was fully converted to LEDs before I got it. They look nice, but I plan on tweaking them. They are a bit too bright for my taste, particularly with the mirror blades. I really like the blue DMD, which I added.
Avatar LE was the first game I totally converted to LED...and I started with Cointaker Premium 2-LEDs which are great, but too bright in most of the inserts. So - for most of the white, yellow ,and green inserts I changed to Pinball Life's single LED Ghostbuster and those look great and non-blinding now. I used CT Pinks in Eywa & Valkyrie. I used CT cool white frosteds in the GI and those look great....less "spotty" than the clear dome type, and they "blend" the plastics art nicely - you don't see the "Stern pixels" as much. I used blue Retros under the Link Pod (there are blue regular bulbs there from the factory)...a blue PBL flasher under the Link insert...white PBL flashers for the other playfield flashers....warm white LEDs in the pops (cuz of the explosion artwork on the pop caps). Game looks beautiful w/ these combinations & brings out the natural colors.
I also recommend putting stronger coils in the game. I upgraded mine to the same ones that are in Ironman (but opposite) ...I forget the #'s offhand but I can post them later. With stronger coils the game jams SO FAST. I felt like my timing was off a bit w/ the stock coils ,but w/ the IM coils - it feels so perfect.
