but I recommend a PM via Pinside.
I have had a set of Pinstadiums(PS) and a set of Pinball LED Lighting Rails (PLLR) for my RRWOZ. My preference is for PLLR.
While both PS and PLLR do a great job adding extra light they are really different approaches.
Here are a few points of comparison based on my experience:
PLLR:
-One size fits all.
-Single warm white color.
-No game interaction.
PS:
-Different options and configurations
-Many color options and configurations.
-Interacts with general illumination (flashes with GI etc...)
PLLR:
-Magnetic mount to rails. No machine modification required.
-Very easy to move from one game to another(less than a minute.)
-Must be removed to raise playfield.
PS:
Two types:
-Magnetic tape required to be installed on cabinet (light bars must be removed to raise playfied.)
-Alternately there is a riser system that attaches to the playfield but I have zero experience with this approach (raises with playfield.)
In either case moving to a new machine is a lengthy process and all PS will not necessarily work with all pinball machines.
Wires tend to be affixed and routed via the backboard portion of the playfield.
PLLR:
-Powered by plugging into a powerstrip or wall plug. You won't find a good way to power these from inside the pinball machine.
-Does not turn on/off with pinball machine.
-Zero interconnect with pinball electronics.
-Mobile app to turn on and off.
PS:
-Powered by pinball machine.
-Turns on/off with pinball machine.
-Interconnects with pinball electronics.
-Mobile app to configure preferences.
PLLR are about half the cost of the basic PS package.
Both PS and PLLR when properly installed do not interfere with game play.
You will appreciate the enhanced illumination but when you are playing you won't notice the physical light hardware.
