I think Chris has the most cost effective solution with T12
fluorescent. Halogen is not mentioned much for plant lights in these
forums although it does make a good heater. There are two other types
that are popular, T5 fluorescent (Expensive) and compact fluorescent,
which are used as spot lighting although some folk are using the 125
WATT units for larger applications.If you search this forum for
lighting you will be covered up with information.
One T5 source is at;

That should give you the T5 info. Note that the Hi-Bay units focus the
light correctly for plant lighting and the silvered reflectors capture
all the uplight and redirect it to the plant. Good $tuff ;-)).

The whole lighting thing has to be cut to fit your situation and
budget.

I'm looking for a way to suppliment my plants with lighting during the day
this winter. Are halogen lights, like shop lights on a stand, sufficient.
The plants are near or in windows, but I have too many plant and not enough
windows.
