Lenses - extra 40° lenses which can be easily changed just requiring a small Phillips head screwdriver. The reason we have included these extra lenses as an optional extra is that if you need to place the lights closer to the plant then spreading the light by using wider lenses will allow you to do this. You will also find this useful if you are using it to grow snow pea sprouts or other salad greens where you wish to accomplish it in the smallest possible area as possible i.e. having the lights as close as possible to the plant. Remembering that the more you spread the light the less the intensity, but the closer you place the light source to the plant the intensity increases.

This ability to tune your growing environment by simply changing the lenses gives you unparalleled flexibility in being able to fine tune lamp placement with respect to plant requirements allowing you to cover just about all possible growing situations.
