1st LED grow..need CFLs? using a progrow 260

hey so I just switched to flower and am wondering if any added CFL bulbs will help produce a more substantial yield...the plants them selves look fantastic each measuring just under 17" at the start of flower...which bulbs would you all consider adding to the tent? I'm using a 3x3x5 dark star by secret jardin...
thanks y'all!

Why cfls? CREE, Philips, Utilitech, EcoSmart sell household led globe bulb.

Although I have a ufo 90, my plan is to grow through harvest using only globe bulbs
