Do you have OCD? Maybe you should!
LED OCD was created to allow pinball owners to fully control the lamps in their machines. This allows the use of any combination of LEDs and standard lamps without any of the side effects.
Control the brightness of individual lamps
Eliminate the flicker or strobe effect when using LEDs
Smooth on/off transitions when using LEDs
Here's a slow motion video of a customer's Twilight Zone. The GUM, BALL, LOCK 2, and bottom pop bumper have LEDs. All other are incandescent.
My personal TRON machine, with and without LED OCD. The most noticable difference starts at 0:30.
The video below was created by another customer. Thanks.
