I can't tell if that light has the two different T5 bulbs...

The 6500K is TL5 HO/54W/865

The 3000K (too high in the spectrum IMO) is TL5 HO/54W/830

Ande...when your friend is ready to force flowering, he'll be wanting the 3000K bulbs if he wants to see the sort of results hoped for. $15-20 each from most grow suppliers.
