Quoted from littlecammi:I have five Pinstadium kits on order (and intend to order more as soon as I've received the first five) because the additional playfield lighting they provide is a huge improvement to just about any game. But I'm not that sold on the Pinstadium flasher option because I like the specific locations of the flashers in the games to stand out, instead of the Pinstadium flashers spreading the flashing over the entire playfield. The exception would be using the Pinstadium UV glow flashers on games where the playfield has items that may react very well to UV (such as Scared Stiff if your game has the glow-in-the-dark plastic pieces).
One of the reasons the flasher option was built in under the awning was to control the brightness and also additionally hide the light source. This way it works for the main game flasher to be the focal point and the Pin Stadiums are used to accent that. In the past prior to Pin Stadiums I used to want the flashers to be really bright and I would install 8 or 12 led flashers to get the intensity. However what I found was the light source of that new LED bulb on the flasher was too much and very distracting. I used to literally avoid the shot sometimes.
In the end I realized that I liked the color casting throw of the light but I did not want to see the bulb's ultra bright light source. So with the flasher option you enhance the flasher and increase the throw/effect without the pinpoint led beaming into your eyes.
Also you can always enable or disable the flasher anytime you want. But I have a feeling that you may end up preferring the flasher feature because it really is super cool!! However it's up to everybody's preferences. The way I look at it it's better to have more options at your disposal and if you choose to use less you always can which is why I recommend including the flasher option you as you can't add it later after it's built.
I hope this is helpful and shines some light on the subject.
