There is a wide range of grow lights available. Pays your money, take your choice. Halogen bulbs on the whole are a bad idea as they tend to have a narrow spectrum and get too hot. Generally speaking the best kinds are specialsed fluorescent or gas discharge (eg high pressure sodium), although you can also make an effective LED light. A lot of people just use ordinary fluorescents because they are cheap, though you can get specialised fluorescents with a better matched spectrum.

Are LED's effective? I always think they don't really throw out the right sort of light? It tends to be a bit clinical, even more than the fluro lights??

It depends on the colour. See the graph to the right he

http://en.wikipedia.org/wiki/Chlorophyll

Whether it looks clinical or "natural" to you green plants absorb light in
certain bands, if those are there all is well. If the light is in other
parts of the spectrum (eg green) it is wasted.

The fluorescent tubes designed for grow lights have a lilac tinge to them as
they are made to emit in both the red and blue ends of the spectrum. LED
lighting is more energy efficient than many other sources, whether a given
LED is powerful enough to support indoor plants is another question. At
least being cool you can place them close.
