Quoted from PinMonk:The fact that you have kids playing it makes it even more important to know what the "simulated UV" wavelength actually is. I see no technical specs about it on Pinstadium's site. You could literally be messing up their eyes forever. Kids are still developing and very susceptible to environmental hazards. If it's actually using LEDs in the 390-400nm wavelength range, those are bad for more than passing exposure.
I’m more worried that he has a TWD with young children vs RGB lights.
On a serious note, isn’t pinstadium just rgb lights? If so all modern pinball machines have the same light spectrum. Or perhaps it has dedicated UV leds.
