Quoted from ForceFlow:
On my game, I used 2 SMD fluted bulbs under the slingshots and plastics on the sides.
For the flashers under the ramps, I used flex head bulbs, and turned them away from the player.
Since the bulbs are visible behind the drop targets, I think I used a frosted LED, rather than one of the brighter SMD bulbs--I can't quite remember without looking.
For the feature lamps under the playfield behind the cardboard, I used colored dual flex head bulbs since they were long and rectangular.
Everything else was pretty much 1 SMD bulbs.
Now that the Art released the matrix product line, I was tempted to try and light the upper left area better. Baby Pacman's apron plastics also seem like a good place to use them as well.
Yeah I am trying to figure out how to get a bit more light in the upper left as you mentioned. I used a mix of frosted 1 and 2 smd and used color matched flex LEDs on the cardboard inserts and also on the 123 inserts for the drops. I will have to take a look for the larger size fled heads for the ramp flashers.
