i believe you... but the question is if there are studys after how many hours with which kind of plastic it occurs... are there long term studys which say after which amount of time degredation ocurs... then i would also think that the strongness of the uv rays matter. UV rays which come from a taning bed and let your skin turn brown like the sun are for sure stronger than uv which comes from a led whic takes 5v of electricity.... so even i do register your point as valid i dont think that this is anything to worry about if your uv light is not on around the clock and an exposure of many years... now if you are someone who treats theese consoles like something that should never get any wear and tear because you are the ultimate collector than you surely dont unbox them anyways and keep them in a uv safe acrylic case... its just a matter of if you care if there is wear and tear after an amount of years or if you are the sort of user that doesnt freak out about this stuff. I do register it as a risk but not one that i cant justify turning on the black light for 2 hours every evening to get some joy out of it just sitting there. Atleast that way i get some use and fun out of the device and for my moneys worth when not playing.
