## Long description

The KR 90 Ring Light from Kaiser Fototechnik is a compact professional ring light with 30 three-chip high-performance LEDs and a color temperature of 5500K. The integrated 1500 mAh lithium-ion battery provides up to 3 hours of operation, while the durable duralumin body houses the electronics and battery. The lamp produces light intensity comparable to a 30 W fluorescent lamp, with a wide beam angle of 110°. The basic connection thread is 77 mm and adapter rings for 55–72 mm are included; an optional adapter plate enables tripod mounting. A quick charger and a 12 V car charger cable are supplied.
Advantages
The KR 90 delivers daylight-balanced 5500K illumination from 30 high-performance LEDs with minimal light loss when running on battery. The durable duralumin construction integrates the battery and circuitry for a compact, lightweight unit (14.2 cm diameter, 300 g). Adjustable output lets you dim the light down to 50%, and the wide 110° radiation angle ensures even illumination. Multiple adapter rings are included for use with lenses from 55 to 72 mm, and charging options include a fast charger and car cable.
Suitable for
Close-up and macro photography

Switch the lamp on and adjust brightness with the dimmer control to achieve the desired exposure; the light can be reduced to 50% output. For tripod mounting, attach the optional adapter plate if required. The device is designed to maintain light output without loss due to battery consumption.
Usage recommendations
For even skin tones and minimal shadows in portrait or close-up work, position the ring light concentric to the lens axis and use moderate dimming. When shooting macro subjects, ensure sufficient working distance and adjust brightness to avoid overexposure. Charge the battery before extended location shoots and carry the car charger for longer sessions.
