Use it on-camera or off-camera while drawing power from an AC cord or via batteries. The large, digital display is easy to read so you know what your settings are. A touch control panel provides precision operation of the LED504B. Or use the included remote for wireless control. Barn doors direct the light exactly where you want it and are removable. The Bi-color design lets you adjust the light's color temperature for a warm, cool, or neutral effect.
