The 18" Bi-Color LED Ring Light from GVM is a unique light source that envelopes your subject in soft, nearly shadowless light that is very flattering to skin tones and renders interesting catchlights in the eyes of your subject. GVM also includes a diffuser for those who want a soft look. While the light can be used off-axis on the included stand, its effect is even more pronounced when you shoot through it with a camera's lens or a smartphone in its holder in the center of the light. The ring light has color temperature that's variable from a warm 3200 to a cool 5600K to match other fixtures or ambient light situations or for creative effects. Both color and light intensity are adjustable on the unit or with your phone and the provided Bluetooth receiver. A 110 to 220 VAC adapter is provided, as is a carry case for storage and transport.
