Control Technologies

Forward Phase - Also known as leading edge, incandescent, MLV, or triac-based dimming. The vast majority of dimmers installed today are this type. This is a line-voltage dimming method.
Reverse Phase - Also known as trailing edge, ELV, or FET-based dimming. Luminaries with electronic supplies are best controlled with these types of dimmers.
3-Wire - A line-voltage dimming method where power is delivered over a dedicated Switched Hot wire, and the phase control dimming signal is sent over a separate line-voltage Dimmed Hot wire.
0-10V - A low-voltage dimming protocol defined in IEC standard 60929-E2. Luminaries that use this standard provide a voltage, which the control forces to 10V for high end and 1V for low end. All fixtures on the same 0-10V link must go to the same light level.
PWM - A low-voltage dimming protocol defined in IEC standard 60929-E3. It uses the duty-cycle of a signal to communicate light level to a fixture. All fixtures on the same PWM link must go to the same level.
DMX - A low-voltage dimming protocol, formally called USITT DMX512-A. It provides high-speed individual control of up to 512 fixtures over a digital link.
EcoSystem - A digital protocol developed by Lutron and based of the DALI standard (IEC60929-E4). It provides individual fixture control for up to 64 fixtures over a digital link.
Switched - Fixtures designated as Switched are unable to be adequately dimmed with Lutron dimmers.
