If you talk about poor men's stadium lighting take 8 old lamp holders.
Then paint them black, put some very bright leds in them and place them around the playfield.
They flash on and off with the GI (The apron has also leds under the graphics).
Below picture is made in the dark.
Welll.... cheaper than this is imposible.

8 old free sokets, 8 ultra bright quad leds (cold white) €10 euro, black paint 3 euro, shrink tube 2 euro.
Total cost € 15 euro.
Lamps are placed so that they don't shine in your eyes.
Lighting the whole playfield looks like playing out side on the street.
You see everything but the mistique is gone.

My homebrew MM with 9 led spots on and off.
Photo taken in the dark, no flash.
So you can play it in total darkness.
And cheap to make ( Closeup is with flash).
2x led upper playfield, 2x led pop bumpers, 3x led castle wall and left and right slingshot.
I use ultabright quad leds and old bayonet sockets.

my latest creation with 10 old gi sockets powered by ultrabright 6.3 volt leds.
If you use spots you can control the color and places where to light up instead to use strips.
