Kaiser KR 90 Ring Light. - Fotospeed
Kaiser KR 90 Ring Light.
The Kaiser K3250 KR 90 LED Ring Light is a professional rechargeable lighting solution designed for close-up and macro photography. Featuring 30 high-performance three-chip LEDs, a daylight-balanced colour temperature of approximately 5500 K and a colour rendering index of CRI 94, it delivers bright, even illumination with minimal shadows. Its integrated lithium-ion battery, adjustable brightness and included lens adapter rings make it a versatile choice for detailed photographic work, both in the studio and on location.
Professional LED Macro Photography Lighting
Kaiser K3250 KR 90 LED Ring Light
Designed for photographers who require consistent illumination at close working distances, the Kaiser KR 90 combines powerful daylight-balanced LED lighting with a compact, rechargeable design. Its circular arrangement of 30 high-performance LEDs helps minimise unwanted shadows, while adjustable brightness, a wide 110-degree radiation angle and versatile mounting options make it suitable for detailed macro and close-up photography.
30 high-performance LEDs
Thirty three-chip LEDs provide bright, even illumination around the lens, helping minimise shadows in close-up and macro photography.
5500 K daylight illumination
Daylight-balanced lighting with a CRI of 94 supports natural colour reproduction when photographing small objects and fine details.
Rechargeable battery
The integrated lithium-ion battery provides approximately three hours of operation at full brightness, with longer runtime possible when dimmed.
Versatile mounting
Includes six lens adapter rings from 52 to 72 mm, together with a 1/4-inch tripod thread for alternative mounting arrangements.
Precision lighting for fine detail
Consistent illumination for macro photography
The Kaiser KR 90 LED Ring Light is designed to provide even, virtually shadowless illumination for close-up and macro photography. Its 30 three-chip high-performance LEDs produce approximately 2100 lux at a distance of 30 cm, while the exceptionally wide 110-degree half-value radiation angle helps distribute light across the subject.
The ring light incorporates a rechargeable lithium-ion battery and the complete control circuitry within a robust duralumin housing. Brightness can be reduced to suit different subjects and working conditions, while the electronic regulation prevents illumination from decreasing as the battery discharges. Automatic shutdown protects the battery against deep discharge when its charge is exhausted.
A minimum working distance of just 3 cm makes the KR 90 particularly useful for capturing fine details at close range. The main mounting connection uses a 77 mm thread, with six supplied adapter rings accommodating lens filter threads from 52 to 72 mm. A 1/4-inch tripod connection offers additional mounting flexibility, while the included quick charger and 12 V car charger cable make the light practical for studio and location photography.
