The X4DL Deluxe Booster goes between the Battery and most Lumedyne Power Packs to add upto 400ws to the Pack above it. It has TWO additional asymmetrical head Jacks that can be powered at 100ws or 200ws regardless of what the Pack is set at. The front one can be boosted by the back to go to 400ws. This allows for the world's widest variety of asymmetrical power options.
It has a switch for each of the two Head jacks in order to select the power or to send the extra Boost power up to the Pack above it. It is only about four inches tall weighs about three and a half pounds and can add an f-stop to the 400ws Packs since it doubles the available power. These Head jacks sync together with the rest of the system only one Head needs to be triggered and the rest sync together.
