Product Description
Offering both continuous lighting as well as customizable flash modes, the RF550D LED Macro Ring Light from Bronic is well suited for macro photography and scientific applications. The light boasts a guide number of 49' and an effective working distance of 4.9', achieved with 48 individual LEDs that are scattered around the ring. Another notable feature is a large color temperature range from 3000 to 15,000K, which enables a wide range of tones from warm orange to deep blue. You can further modify the quality of your light with the four included diffusion filters: orange, blue, white, and transparent.
For installation, attach the light to your lens with one of the eight adapter rings provided, which range in size from 49 to 77mm. Load four AA batteries, available separately, onto the control unit, then either mount it on your camera hot shoe for easy operation or use it handheld by extending the 39" long coiled connection cord. On the back of this control unit is a backlit LCD screen that displays the output power, current mode, and the battery level. Dedicated buttons allow you to choose LIGHT for steady lighting, FLASH for strobe operation, and L and R modes for using only the left or right side of the ring light. Finally, you can also adjust your output power in seven different steps from 1/1 to 1/64 or dial in exposure compensation and bracketing configurations.
