Well, guess what. You are likely to be diagnosed with Seasonal Affectation Disorder (millions of Americans are afflicted by it, particularly in the short-day states) aka SAD, and your physician can prescribe incandescent lights to keep your spirits up.
You have no shortage of incandescent bulbs in your future.
The problem with your theory is that light therapy involves types of fluorescent light, not incandescent light. There are no makes of full spectrum incandescent bulbs, and more advanced therapeutic options, are also fluorescent.
