19° Spotlight Lens:

Perfect for anyone who needs max. Light output and wants accurate control of light beam;
Suitable for large setup when you need the Light beam to be strong;
19° Spotlight Mount has twice the light output of 36° and 20% more than 26°;
Its beam diameter is approx. 1/2 of 36° Spotlight Mount.

26° Spotlight Lens:

If both light output and beam diameter is important to you, this may be the perfect solution;
It has approx. 20% less output than 19° Spotlight Mount;
Beam diameter approx. 65% of 36° Spotlight Mount;
More versatile comparing to other 2 options design suitable for more kinds of setups.

36° Spotlight Lens:

Perfect for a restricted setup where a wide beam of light is required;
@3m distance, it has a beam diameter of 180cm which is twice as wide as 19° Spotlight Mount;
36° Spotlight Mount has the least light output among the three options.

Rugged design meets precision optics with the Aputure Spotlight Mount’s interchangeable ecosystem of 19°, 26°, and 36° lenses. These lenses allow film- and videomakers to make the most of their Bowens mount and use a wide range of fixtures, including Aputure’s Light Storm COB 120D, 120D II, or 300D. By simply attaching the lens to the front of the mount, users can enjoy further lighting control and modification on set. With these lenses, you can shape light the way you need it, be it a clean spot effect, a wider illumination circle, or any modelling effect achieved with gobos or barn doors. Different beam angles can be achieved with a simple lens swap thanks to the mount and lens kit’s ellipsoidal reflector spotlight (ERS) configuration. More than that, these high precision optical lenses produce a dramatic but clean beam of light with minimal colour fringing. You can buy the lenses individually or buy the set to get a military-grade casing for easy and secure transport.

Light Shaping Control
Like typical ellipsoidal lights, the Spotlight Mount also offers simple user-interchangeability between Aputure's 19°, 26°, and 36° lenses, whether you need a wider illumination circle or pinpoint accuracy. Combined with the internal shutters, filmmakers will be able to gain more control of the shape of their light.

Precision Optics
The three lenses for the Spotlight Mount were designed with professionals in mind. In addition to allowing the 120d II to produce 10 times its original output, the high-resolution lenses produce an even beam of light, with minimal light falloff on the edges, while maintaining a shift in the colour temperature of fewer than 200 degrees Kelvin.
