im sure someone will come and say they dont exist, but i've been looking at several. The question no is....the ones i have seen use a 0-10v range to control the dimming. can anyone help me find one that does it over line voltage or a method to use the 0-10v via dmx or someother method on a light board???? edit: notes & additional quewstiosn: http://news.thomasnet.com/fullstory/462971 http://www.goodmart.com/products/36104.htm "The QUICKTRONIC POWERSENSE T8 dimming ballast is ideal for use in school auditoriums and classrooms, conference rooms and even private offices. For the individual office or conference room, installation can be streamlined by using a 2-wire power-line dimmer; eliminating the need for additional control wires." does that mean i can wire these straight to the dimmer ciruit or do i need a separate dimmer??
