I am scared to death to walk into a pitch black incall.

i don't want disco lights but dim is just fine.

In a hotel room, I find that what works best is to keep the entry light on, and maybe the bathroom light, but all other lights off.  It makes for a nice glow in the room once my eyes are acclimated.

Of course during the day, you can just keep the drapes closed all but a few inches and that works well.

Some people keep the TV screen on, but I find it distracting.

Then lighting tea light candles throughout the room gives a nice glow, but be sure they aren't anywhere near the bed for safety's sake.

One gal I saw had those LED X-mass lights that she draped over the head board.  That was a nice touch.
