Spirit Temple!
The only way you even get a little incling of what the Temple of Light is like is when you're disabling barriers to Ganon's Tower. You actually have to go through more than 3 rooms in the Spirit Temple, AND you get to have a rather amusing fight with Twinrova ("bicker bicker" HAHAHA I love it), and everyone knows that Twinrova is like Zelda tradition. Plus you get the Silver Gauntlets AND the Mirror Shild which, when worn with the matching Goron Tunic makes Link look sooo awesome.
So there. Bam.
