Is this a good light schdual for a tank with no plants?

[Banana mouse]

I have a freshwater tropical tank with no plants, I turn the light on at 9am then I turn the big light off at 4pm and replace it with a smaller light then that light goes off at 5pm, is that a good time schedule for the tank?

Big light 9am-4pm Arcadia fresh water lamp, 36W 1200mm 48 inches 7,500K

Smaller light 4pm-5pm Glo sun glo 4200K

Details:
The tank has been cycled(fishles), threw out the cycle iv had the lights off and now that iv just added my fish I'm going to start having a light schedule.

Sorry I posted some wrong information.


***Smaller light 4pm-5pm Glo sun glo 4200K*** - that's wrong

Smaller light 4pm-5pm glo life glo 6700K, 30W, 91cm, 36 inches. - that's is the right information
