The RF Wedge White is an upgraded version of the Rockwedge LED light. This model has the following upgrades: 1. The RF Wedge has an RF remote instead of an IR remote. This is important because the RF remote has a long range of around 50-100 feet depending on the area, and the RF signal goes through walls and is not directional. What this means for you is that if you have 24 lights set up, you can just hit red once or twice and all of the lights will change at the same time without having to run to each light and point the remote at it. There are also 2 different RF channels if you want to control 2 separate groups of lights from the same remote. 2. We also added a tri-mode switch to this light. The modes are RF, Master, Slave/DMX. In RF mode the light will react to the remote as explained above. Once a light is set you can set it to be a master light (the remote will not control the light any longer but still leave the color/effect you set it at). You can then set your other lights to slave mode and set them to the same wireless channel color and they will just copy the setting from the master light (whether it is in sound activated mode, static color, etc). After you turn the lights all off and then back on they will all remember these setting for next time you use them.
