Ceramic technology provides an interesting solution for professional lighting designers.  ARRI 
fixtures designed with this technology dramatically reduce transmitted heat, provide 3200K 
light, offer long lamp life and draw minimum power.
After the successful ARRI X Ceramic 250, ARRI Lighting developed a Fresnel style Ceramic 
fixture, which has been equally received. Modeled after the ARRI 2000 tungsten Fresnel, the 
Studio Ceramic 250 evolved into an optimized and balanced lamphead.  User benefits are 
similar to the ARRI X Ceramic 250 design: lamp performance equal to a 1kw halogen lamp, 
cooler housing temperatures, lower power consumption, higher lamp life, ‘hot’ restrike, 
integrated ballast, 3200K color temperature, and a Color Rendering Index >90.
ARRI Ceramic Technology – a new choice!
