I have the basking light come on at 7:15am, followed by the UBV lights at 7:30am. I provide water drip, misting and first meal before leave for work at 8am. Their second meal and water drip is either at noon or at 4:30pm (depending on my work shift). Last meal just before 6pm is a light one because its so clost to "bedtime". The basking light turns off at 6:15pm, and the UVB turns off at 7:45pm. Of course in mid-Summer when the day is long they also get some additional early and late ambient daylight from the window.
