Would you like cave diving as much if the caves were well lit?

I like to swim along with my light pointed at the ceiling a little ahead of me, not quite straight up. I like the twilight effect, and if there are air pockets they'll reflect moving patterns of light back down in front of me.

Ditto

In addition; I think the darkness actually makes it easier to keep track of team members. I'd much rather send and receive light signals than constantly turn around or look back between my feet because its so bright that light signals become useless.
