OK so I bought some clear clear rim buttons a while back with plans on lighting them in the future. Now is getting to be the future so I'm looking around for all my options. The buttons I bought are 30mm white solid plunger with clear rims for the player buttons and a 24mm black solid plunger with clear rim for the start.

So far it seems my best bet is the pele led light ring:

1) How will these actually attach using snap on buttons? Will I have to glue them to the bottom of my control panel?
2) How even will light distribution be without having a clear plunger as well. Will I end up with 2 bright spots?
Next thing I'll need to tackle is led controller. Any advice on this? Any known problems with Sparky led controller:

I would like to have custom colours on specific mame games so this may not work for my intentions. At which point would the Ledwiz be the optimal choice?
If I decide to hold on a controller for a while there should be no issues hooking a power source to either the red, green, or blue line on the pele ring and just having 1 solid colour? As far as I know ledblinky has the option to turn down the brightness (I think I would prefer a low glow). Without using a controller could I simply control brightness by lowering voltage to the leds?
