Godox FLS8 8-Inch Fresnel Lens, Bowens S-Type Mount

The FLS8 is an 8-inch fresnel lens that fits Bowens S-type COB LED lights, including the Godox Knowled M300D. Its concentric-ring glass gathers the light and pushes it forward, raising the effective output by up to 19 times, so the light carries much further across a big set or stage.

Turn it to set the beam anywhere from a 10° spot to a 40° flood. A tight setting throws a neat, round pool of light onto a painted canvas backdrop behind a subject, and a wider one floods a larger area. Barn doors to trim the spill are available separately. The lens body is solidly made and keeps light leaks to a minimum, and it's equally at home on commercial, advertising and fashion stills.

It doesn't fit the Godox M600D or M600Bi because of their mounting rings. For those lights, choose the FLS10.

Use it with LED lights only. Don't leave it running for very long periods, as the lens can overheat. If your setup has a shutter, keep it open while the light is on, because a closed shutter can make the lens overheat and crack.
