Introducting the Mantis adjustable parabolic reflector. The wings form a succession of perfect dual-parabolic shapes when assembled. This enables growers to focus light spread and intensity according to their individual needs. When adjusted to wide settings it may be positioned very near to the plants for both maximum light intensity and area coverage. Alternatively the reflector maybe adjusted to more narrow settings and positioned proportionally further away from the vegetation to suit the light and heat requirements of sensitve plants or more sensitive stages in plant growth.
