I went to Lowes and bought a single bulb fluorescent fixture like what you might see in a garage or workbench, along with a 'daylight' bulb. I put it above the window nearest my desk, and it seems to really help with the murky Pacific Northwest winter. I'd guess I paid less than $30, though I did have to wire up a plug myself (should be no hard task for an HNer). As long as I remember to turn it off by about 9pm, I have no problem getting sleepy by about 11 or midnight.
