This lamp is equipped with a flexible arm, which ensures an easy adjustment of the reflector. The PRIMA-FLEX optics are designed to provide deep, well-focused illumination. The diameter of the light field is 17 cm at 0.5 m. The light intensity can be adjusted through the membrane keyboard. The C button allows you to turn on the courtesy light (ambient light).   PRIMA-FLEX is also the first observation lamp with the possibility to choose an ambient light in addition to the traditional concentrated light. This function can be activated at the touch of a button (C). The transformer, integrated in the plug to give the arm greater lightness, is supplied with interchangeable plugs.
