Professional ring light with 30 three-chip high-performance LEDs and a CRI of 94. It has an illumination intensity of approximately 2100 Lux at a distance of 30 cm. The extremely wide beam angle is 110° (half-value angle). A rechargeable lithium-ion battery and the complete electronics are integrated into the housing made of highly stable duralumin. The light is continuously dimmable. The base mounting connection is suitable for filter threads of 77 mm, and adapter rings from 52 to 72 mm are included. The ring light can also be mounted on a tripod. The electronic regulation ensures constant brightness, even with decreasing supply voltage. An automatic shutdown at too low voltage prevents deep discharge and battery defects.
