The Nanlite FL-20G Fresnel Lens is a glass Fresnel lens with an adjustable-length housing that focuses light output. It features a Bowens Mount and is compatible with the Nanlite Forza 720, 720B, 500, 300, 300B, and 200, and the FS-Series spotlights.

Dial-In The Beam Angle
The FL-20G's rotating barrel design enables beam angle adjustment from spot (10°) to flood (45°) with an intuitive twisting motion.

Increase Brightness
For example, when set to a 10° spot the FL-20G can increase light output of the Forza 300 to 128679 Lux at 1 meter and the Forza 500 to a staggering 217649 Lux at 1 meter.

Thermal Management
The FL-20G's material design was specifically created to handle the heat output of Forza lights running at full brightness without any adverse effects.

Includes Barndoors
The included metal barn doors enable further adjustment of the light output and control of spill.

Quick Change Modifier Mount
To keep up with the speed of production Nanlite kept the modifier mount fast and simple. With one push of a button and a quarter turn, you can swap out the FL-20G for any light modifier using a Bowens Style mount, including but not limited to Nanlite's own line of light modifiers.
