A T8 light should give you good low light, around 30 micromols, if you have 2 inches of substrate. You don't need two bulbs which might be too much light without CO2. Picking a bulb is largely a matter of what looks best to you. I would go for one of the 6500K bulbs, but I have no idea how they differ.
