Putting a bunch of high wattage incandescent bulbs on the ceiling is a waste of time and electricity in the first place. If you want a visually brighter space for mood purposes use halogen bulbs or LED bulbs.
If you want to do "light therapy" the only thing that will work is getting inside a couple feet of a very bright halogen or LED bulb for twenty minutes or so at a time. Ceiling lights or something meters away shining on you are quite pointless. I don't know why Ray Peat has indicated brooder incandescent lamps are useful. I'm grateful to him for introducing me to the concept of light therapy, but I must repeat that shining some 200 watt incandescent bulb in your direction is useless for any therapeutic purpose.
