Me personally, I hardly turn them on anymore unless I'm browsing or showing off my collection. In theory, LEDs should last decades of continuous use, but that's hardly the case with statues. Usually something will go wrong with the internal wiring before the LEDs give out. I have 5 statues with LEDs in total, and 2 from First4Figures (Wolf Link and Midna/Dark Link Exclusive). When I first got the F4F statues, I would leave the lights on for upwards of 4 hours at a time daily, and I did this for a year or so. As of today, Midna's hair still lights up, but Dark Link hasn't been working for probably a year or two.
My suggestion is to use the lights as often as you like, and enjoy them while they work, because they won't last forever. Also, if you choose to do this, it might be a good idea to invest in some rechargeable batteries.
^good info, thanks man
