The Strobies LED Macro Ring Light from Interfit provides adjustable flash and continuous lighting, using LEDs and four AA batteries. It can be attached to any standard camera hot shoe as well as many lenses with 52-72mm filter threads, using the six included adapters.
With a ring light attached to your camera and lens, you can create very soft lighting with virtually no shadows. This ring light has a Guide No. of 46′ (14m) in flash mode, with a color temperature of 5600K. You can select flash or continuous light mode using the slider on the rear of the control unit. Choose between “F” for flash, “L” for continuous lighting, and “Off” to power down the light. You’ll also find a test fire button to ensure the flash function is ready, and a dial to dim the light from high to low output.
The ring ight is powered by four AA batteries, which should last up to three hours in continuous lighting mode. The light is attached to the control unit by a coiled cable, which is 1.8′ long when relaxed, and up to 6.5′ when stretched. Attaching the control unit and ring light is simple, and adjusting your light settings as you work is easy.
