The type of bulb doesn't matter. Only difference would be the spot light enclosed type might better direct the light where you want it.

When your looking for which color of bulb. You should look for it's kelvin rating, not what color it says you'll see(like cool white, day light...). For growing you want 6500K(best), 5500K(better), 5000K(acceptable). For flower you want 2700K.

If you look at the base of the CFL they usually have the kelvin rating printed on there. :thumbsup:
