Reflectors without baffles are very
inefficient so light is lost. Baffles
direct the light downward.New fluorescent configurations have
made it easier to build a garden. Circle
tubes and thin tubed 8" doubles screw into
incandescent sockets. Although these
bulbs are not very efficient they are step up
from incandescents. Combinations of circle
lights and tubes can illuminate a garden
very brightly. They can be used in
extremely small spaces. These lamps
always seem to be on sale. When electrical
costs are not a factor they are a
inexpensive way of setting up a garden.
