Re: which wire is which ?
Well, you're already done so this is probably moot, but it might help someone else.
Look closely at the wires on the light fixture. One of them will have linear ribs molded into the insulation; the other will be smooth. The one with the ribs is the neutral and connects to the white wire in the box; the smooth one is the hot and connects to the black wire in the box.
The neutral wire connects to the interior shell of the socket; the hot connects to the center contact. By wiring backward you make the shell "hot" and that increases the possibility of electrocution or fire in the event something or someone contacts the shell or the base of the bulb when changing it.

The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
