From the Manufacturer:

Our most popular kit configurations are the two-head kits. These appeal to photographers buying studio lighting for the first time as well as established photographers looking for an exceptional value. Typical two head kits include two Gemini monolights with two Bowens lighting support stands. To control the light we include 2 silver/white umbrellas and two wide-angle umbrella reflectors.

In our experience, this creates a very easy-to-use and effective two-light setup. The umbrellas are perfect for portraiture and many still-life applications - the black cover can be removed allowing you to fire the light through the umbrella like a softbox.

These kits now include a Pulsar Tx Radio Trigger and a Pulsar Rx Radio Receiver Card to wirelessly sync your camera to your lights. The kits include a sync lead for camera connection and all the power cables, modelling lamps and flash tubes. Everything is then packed into a Trolley Case and Stand Bag for easy transportation.
