And yet reading at home for half an hour can be a chore because your eyes get tired, or you fall asleep? Is "Full spectrum" lighting the answer? I've read a little bit about full spectrum lighting and natural spectrum lighting. Nowhere does it say what the difference between the two are, or if there is any difference. In conducting these searches, there seem to be many claims that full spectrum lighting is extremely effective, but have not seen many user reviews or opinions.<br> <br> I notice in the bookstore or library they just have standard recessed lighting, but when the light shines on a book it seems to be clearer than with using a halogen desk lamp.<br> <br> Can you get these kinds of bulbs for standard recessed fixtures or lamps? If so, which companies make them and are they available in a regular store?
