>>I Bought a SAD Lamp and It Made Me Happy

My BIL has issues with SAD - and lives in the Pacific NW. Talk about gloomy winters(!)

He dealt with the issue by replacing all his lights with 6500K ('daylight') LEDs - and says it works. So if you get gloomy yourself in the winter, those LED bulbs are a lot cheaper than Varilux panel lamps - plus you don't have to take time to sit (or stand) in one place and get exposed to the light.
