ETC S4LEDS2THD-0-A
Source Four LED Series 2 Tungsten HD Engine Only

OUR PART #  S4LEDS2THD-0-A


Though it may look the same on the outside, the ETC Source Four LED Series 2 is the evolution of LED lighting, offering even more of what makes the Source Four LED the best LED profile available. This particular product [ETC model: S4LEDS2THD-0-A] is the Source 4 Series 2 LED Tungsten HD Engine Only (lens sold separately), and features a standard Edison connector. With finely-tuned electronics and optimized arrays, the Series 2 delivers a combination of light quality and output that can't be matched.

The Source Four LED Series 2 Tungsten HD arrays are designed for broadcast lighting, offering flicker-free operation, and high-definition lighting. With a new mix of LED emitters, the luminaires' output is significantly brighter than the original Source Four LED white-light arrays. The Tungsten HD array matches conventional tungsten lighting, with adjustable warm-white (2700 to 4500K) light. They offer tint control, so they can be tweaked to perfectly illuminate individual skin tones. The Series 2 LED light engines work with all Source Four lens tubes, giving a high-quality, controllable beam of light. For the best results, it is highly recommended that EDLT versions are used. We also offer a special LED-only version of the 50° lens tube.
