As another respondent has already told you, the way to go is definitely the
fluorescent tube style of bulb.
As he states, all standard formats (warm white, cool white, etc.) will do
the trick for you, but here in North America (I'm in Canada), there are
special plant grow fluorescents that have a broader spectrum of light and
definitely produce superior results growing plants. The slightly higher
prices over standard formats is worth the small price difference.
As the other person also stated, halogens generate enough heat to fry an egg
and an additional practical consideration is that your electricity bills
will go through the roof as the energy consumption is very high for
halogens. The average 122 cm fluorescent tube used to run 40 watts but the
new standard here is now around 32 watts, due to energy consumption
