Same brightness.....Just color temperature.
One would match the rest of the GI, so either Cool White, or Sunlight for a Game.
(I personally only use Sunlight, unless its a black game like TZ, so this title is either white)
Id grab 6 bulbs, and know if I used 4, I had spares....Any Dark GI area, especially the back, where
a Manufacture usually only put one to 2 bulbs, will glow like there is 4-6 bulbs.
Twin 2835, Cointaker or Comet, Frosted, are still best for GI.
Strips for the back or Apron, cant hurt, but not needed, unless you play in the dark.
New Mod from earlier to light playfield, only when active, or strips placed there for a couple dollars, also
will light on all the time.
Frosted strips, and if in the back, get a dimmer switch....some reflection possible, or mount by paddle.
I hope to get some pics, and this up after GB MODS...just busy.
Just look at everyone elses pics, and decide the colors you want for main insert modes....its pretty straight forward color match lighting.
Biggest diff is the flashers....I went all Purple above the playfield in domes, but whatever the taste, go bright with a 10 SMD in the back ones, and its amazing!
