I use the opti light as well but use the daylight bulbs in the celing fan, not quite the same..... Now those opti lights are even at wally world (or what they call Daylight Lamps). Replacement bulbs can be found at Home Depot, or Lowes, or office supply places, or even cheaper on the net. They sure do help with depression--or complete bordem.. it adjust your attitude somewhat...When I purchased mine they were not cheap, so I keep them in the Sewing and puter room.
