I think the best use of light effects are in the Zalactic Labs Caves... Especially when you fall down that huge water fall and you see the lanterns hanging overhead while you walk along the wooden walkways... (BTW: The rest of Zal labs will be completed soon........)
Also, I think there should be a system so that lights outside (ie torches, lanterns etc) should only turn on at night. It would look alot better than running constantly for no reason
