Ideal UV wavelength for curing?

Hey there!

So i made my own post-print curing box using some 370nm 3 Watt UV LEDs, however I’ve noticed my prints gain a very slight tint of lime green after leaving it in there after an hour or two.
Would this be due to the shorter LED wavelength? I was told that 370nm is the ideal wave length for UV activated resin, but now I find other sources tell me 405nm.

I made box too, but used 405nm LEDs. Clear turns an old looking yellowish in it, but it seems to do that anyway on it’s own. So, I guess it possible as I don’t notice any difference in hue. Does it end up a different color if left in the Sun? (I’m assuming we’re talking about clear here)
