The Nanguang Luxpad23 On-Camera LED Light is a compact LED light that you can use atop your camera, or to complement an existing lighting setup. If attached via the built-in shoe mount, the fixture can be articulated using the tension knob. Turn the knobs on the rear of the fixture to adjust the light output from 0-100% and color temperature between 3200 and 5600K. The light can be powered either from a separately available NP-F (Sony L-series) battery via the built-in mount, or with a separately available DC power source via the barrel connector.
