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.
