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 here:

 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.
