The Alpha 4K's concept is to create a more compact and lighter fixture with interchangeable Fresnel lenses, giving the end user more options than just flood and spot.
This new approach of to the Fresnel concept reduces almost half the depth compared to traditional Fresnel fixtures.
Optically, this new product offers great versatility from Open-Eye (86°) for extra wide beam with a single hard shadow to precisely controlled Fresnel from 7° to 65° using the two different Fresnel lenses: Spot or Flood.
With its wide variety of beam angle, the Alpha 4K is capable of replacing, with better performance, any open face and Fresnel and in some configuration a Par.
