Alpha Profile 800 ST

The Alpha Profile 800 ST is the most modern moving beam shaper in existence today for use in the most demanding lighting sectors.


Clay Paky has used highly sophisticated micro mechanics to obtain a compact, light, silent unit with an extremely bright light and a zoom capable of producing an extraordinarily sharp, perfectly uniform beam. Lighting designers will find all the tools they need  to enhance their creativity in the Alpha Profile 800 ST: a miniaturized four-blade framing system, capable of creating any geometric shape; a zoom that starts from the extremely narrow angle of 7.6° and reaches up to 55°; an exclusive autofocus system and the Dyna-Cue-Creator function, which are two useful features created by Clay Paky to make their lights easy to program and enrich them with original dynamic visual effects.

The 6000 K light beam and top-of-the-class operating silence complete the characteristics of this light. It is perfect for use in Theatres, Television studios, on exhibition stands and in the most demanding live situations.
