Lightbox CFLs (full array)
These are 23W (100W equivalent) soft white CFLs with a 2700K color temperature.
Soft whites are easy to get; I can always swap in "cooler" colored bulbs (4000-6500K) for a more daylight effect later. What is important here is that this bulbs emit 1600 lumens each for a total of 16,000, which is well above the 10,000 lumens needed for SAD therapy.
