Portable RGB LED Fill Light with App Control, Bi-Color Adjustment & Magnet Base
The Viltrox Weeylite K21 RGB LED Fill Light is a versatile handheld light stick designed to bring professional-quality illumination anywhere you need it. Compact, lightweight, and packed with 160 high-quality RGB and white LEDs, the K21 delivers soft, uniform light with excellent colour rendering (RA 95 / TLCI 97), perfect for photography, videography, live streaming, makeup tutorials, or scenic lighting.
Its polygonal design and built-in magnets make it easy to attach to metal surfaces or fix with a tripod or light stand via 1/4"-20 screw ports on both ends. Hide the light sources in corners to create dynamic effects or provide close-range illumination wherever you need it.
