How do I position a rectangular hood in my rectangular garden?

[SmokeyMacPot]

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.

If you want to see where your light is going take a string and run it down the side of the hood to the floor at the angle the hood is placed. That is the width of your light cast. You obviously place the plants in that zone/ utherwise you can buy a light analyzer and figure it out that way.
