I'm not sure about the two hour timespan, but brightness appears to have an effect on sleep latency and the time it takes to fall asleep. Studies [edit: PDFs]:

Definitely install F.lux: http://stereopsis.com/flux/ http://stereopsis.com/flux/ It adjusts the color temperature of your monitor as the sun goes down. As the sun sets, your monitor becomes more red/pink. It takes a little while to get used to it, but I absolutely cannot stand normal monitors at night time now. When I occasionally disable F.lux to watch a movie at night, I'm blinded by the bright blue glow.

  I've recently done this, and it helps when I'm on-call and get woke up in the night. I can now fall back asleep faster. Another item that helped, I've put oil lanterns up on the walls in my home office. I just got to remember to light them instead of flipping on a light switch, and all is good.

    That's a nice touch I hadn't thought of. Any ones you like in particular?

      I picked up a couple of generic ones, I think they are made by Lamplight Farms. They include a bracket that hangs on the wall with a reflector plate. Other than the wall mount, most of the oil lamps are about the same (that is, the ones in the $5 - $20 range). Of course, I picked up these ones about 10 years ago, and I can't find this particular model any more. I can only find the table top ones (could probably put it on a shelf, with a mirror behind it for better effect). You can use either lamp oil or kerosene in most of them, the lamp oil doesn't stink as bad (and if you get the "ultra pure" oil, there is hardly any smell at all). Also, last time I had a power outage I was able to keep the flame lit (on a pilot light height) through the night with hardly any oil used (and it made a nice night light -- don't know how safe it is though).
