The ECO Farm MG8 660W LED Pro doesn’t use lenses to distribute ligh. Instead, it has 8 bars and creates uniform coverage by actually positioning the LEDs physically above all plants in a set area (150cm x 150cm).The fixture itself is 110cm x 109cm x 7.2cm (tall). All plants are directly under the source of light, so you don’t get hot or cold spots. And because the light isn’t directed out and away from the fixture, you also lose less light to walls.
