T5s or T8s and color temp

I have the option of getting 3000K t5s or 2700K T8s for flowering.

Is 2700K better than 3000K for flowering?

If so, would the increased efficiency (more light) of the t5 make up for the poorer color temp?

These are regular bulbs btw, not HO. (they are just for suplimental lighting, I will be pairing them with an HPS)

well before you waste the money you should know that the HPS will trump the T5 or T8 by so much in lumens that you are essentially wasting the light. It would be like using a flashlight in the daytime. I use the 2700K T5's for flowering and they work great btw.
