The D-Lite RX 4 is a portable, multi-voltage 400Ws monolight featuring five stop power control in 1/10th step increments. Fast recycle times of as little as 0.35 sec keep you shooting without hesitation, and a 1/800 sec flash duration at full power is well-suited to freezing fast-moving action.
The flash is also characterized by its integrated EL-Skyport receiver, which is compatible with the included EL-Skyport Transmitter Plus for wireless remote triggering and power control from up to 656′ away.
This transmitter allows you to trigger and set flash power for up to four groups, as well as an all groups setting, and 16 different channels, which are split between eight normal channels and eight hi-speed channels.
A locking metal accessory shoe connector allows you to secure the transmitter directly to a camera, a top hot shoe and a 2.5mm sync port are available for directly connecting an additional strobe, and a swiveling design helps to improve reception for more direct transmission.
