The
majority of light originates from the sides of the
reflector, which are parallel with the bulb; this can be
ascertained by simply looking at the pattern of light
shining on the walls and floor. The sides of the
reflector are angled, and on many hoods the light
footprint can be easily adjusted to suit your
requirements. So remember, if you have a rectangular
garden, it is important to position the longest side of
the reflector parallel to the shortest side of your
garden.
