I use a Lumie desk lamp, which is a good mood booster on the dark mornings. I went for the desk lamp rather than a light box as it's easier to keep with the required distance than the light boxes, which are quite a bit bigger. Also, the desk lamp has a dimmer switch, so the light can be reduced to normal lamp levels. I use a body clock too - it's a much nicer way to wake up, instead of an alarm.
