It's a Source Four® and an LED. ETC created Source Four LED™ luminaires to produce the most beautiful light possible from an LED source. You get the crisp optics, user-friendly functionality, and convenient size and shape that you love about the Source Four family of fixtures, along with the capable user-interface and high efficiency that made you fall for ETC's Selador Desire™ line of LED luminaires.
Studio HD's flicker-free mode prevents the undesirable side effects that commonly arise when using LEDs with high-speed and rolling-shutter cameras. No external controller required! With its stand-alone functions, the Studio HD is a brilliant add to your lighting kit.
