Be wary of tCDS - no long term studies. Also 'no such thing as a free lunch' - see gwern : http://www.gwern.net/Drug%20heuristics
Not included and should be: very bright light. http://lesswrong.com/lw/gdl/my_simple_hack_for_increased_ale...
The best solution I found for increasing alertness is also the hardest, but it works for me: go to sleep at the same time every day, don't linger in bed after waking up, and exercise in the morning.
There's also the color temperature of the light, which I definitely notice. I use f.lux/redshift as well as red light bulbs at night, and sleep with blackout curtains. On the flip side, I find it hard to wake up in a pitch black room, so I set two clip lamps aimed at me on a timer instead of an alarm.
What would be really nice is to have light bulbs that adjust both brightness and color temperature to mimic the sun. It would be interesting if mimicking a tropical sun cycle would help with seasonal affective disorder.
I've heard good things about bright lighting too. Unfortunately, my apartment's wiring can't support multiple 100W bulbs. Anyone have any tips on super-bright LED lightbulbs (that don't cost a fortune)?
I work in a home office though, and do have a window.
Its worth noting that GE now makes some fluorescent tube replacements with LED that have a much more complete spectrum. For those with Fluorescent fixtures above your desks, they will help improve the quality of the light you have. I've put them in my woodshop with great success.
