I would get a HO T5 6.5k Daylight bulb. If you don't already have a T5 fixture you might want to considering upgrading to a double fixture with one Acradia Bulb for UVB and one 6.5k Daylight bulb for full spectrum lighting and plant growth.
I use this same fixture over all of my chams and love them. They are inexpensive, free shipping, and come with 2 6500K plant bulbs. I will actually be using these over my babies with 1 reptisun 5.0 and one 6500K bulb.
