The RL-130 from StudioKing is a universal 5W lamp with a CRI value of 90+. Thanks to the included adapters, you can easily attach the RL-130 to your camera lens. By pressing the buttons on the left and right side of the ring lamp, you can simply click the ring lamp on the adapter ring. The RL-130 has a color temperature of 4800K. The controller can be placed on your camera's hotshoe. Use the buttons and the screen to control the RL-130. For example, you can choose a mode in which the LEDs burn continually and a mode where the LEDs light up briefly when a picture is taken. Optionally, you can only turn on the left or right half of the RL-130. The brightness of the LEDs can also be adjusted. A blue and orange ring are included for a warm and cold color temperature. The RL-130 is powered by four AA batteries (not included).
