In the SKYMASTER ZKP 4 LED, ZEISS combines two leading-edge technologies to deliver extremely bright, tiny and pin-sharp light dots: ZEISS fiber optics and LED lighting. The projector was introduced in 2011. Never before has an artificial sky been as close to the natural one. Thanks to LEDs, the stars are not only three times as bright as before, but also pure white compared to slightly reddish hue of halogen-lit stars. SKYMASTER ZKP 4 comes with eight object projectors. They can display all the planets as well as project other objects of the solar system. SKYMASTER ZKP 4 is a modular system. It is up to the user to decide which didactic functions shall be included.
