## Long description

KAISER KR 90 is a compact professional ring light with a 14.2 cm diameter and a neutral 5500 K colour temperature that provides consistent daylight-balanced illumination. The lamp is equipped with 30 three-chip high-performance LEDs arranged to deliver an extremely wide radiation angle of 110°, producing light intensity comparable to a 30 W fluorescent lamp. The main body is made of durable duralumin, houses the complete circuitry and a built-in 1500 mAh rechargeable lithium-ion battery that enables up to 3 hours of operation. The white housing and light 300 g weight make the KR 90 portable for portrait, macro, product and close-up photography or video lighting.
Advantages
The KR 90 offers a high colour temperature of 5500 K for neutral daylight rendering, combined with a broad 110° beam angle for even, shadow-reducing illumination. Its 30 three-chip LEDs deliver intensity similar to a 30 W fluorescent lamp while the integrated electronics allow dimming down to 50% for adaptable light control. The rechargeable 1500 mAh battery provides up to three hours of cordless use, and the durable duralumin construction keeps weight low while protecting internal components. Included adapter rings and charging accessories increase compatibility and mobility.
Suitable for
Portrait and headshot photography
Macro and close-up photography (insects, jewelry, small objects)

How to use
Mount the ring light on a compatible lens or use the included adapter rings to fit the connection thread to your equipment. Charge the built-in battery with the supplied quick charger or use the 12 V car charger cable for charging on the move. Power the unit and adjust brightness to the desired level; the dimming function allows reducing output to 50% for softer illumination. Position the light close to the subject for portrait, macro or product work to benefit from even, shadow-minimizing light across the field of view. For extended use, monitor remaining battery runtime and recharge as needed.
Usage recommendations
For accurate colour rendition and consistent results, set your camera white balance to 5500 K or use daylight white balance presets. When shooting close-ups, start with medium dimming to avoid overexposure and move the light incrementally closer until the desired illumination and shadow control are achieved. Use the adapter rings supplied to ensure a secure fit and consider adding a tripod-mounted adapter plate (optional) when you need stable support or hands-free operation.
