A dimmable driver for an LED light fixture allows multiple types of dimmers to be used with the light fixture. The dimmable driver may be disconnected from one type of dimmer and subsequently connected to another type of dimmer without having to replace or otherwise adjust the driver for each dimmer. Multiple types of dimmers may be connected to dimmable driver at the same time and the dimmable driver may use dimming signals from one or several of these dimmers. In some embodiments, the dimmable driver is configured to accommodate a step dimmer, a 0-10 V dimmer, and a phase-cut dimmer. Other dimmers and dimming protocols may be accommodated by the dimmable driver in alternative embodiments. Such an arrangement maximizes flexibility for lighting specifiers, contractors, and distributors while minimizing potential errors, costs, delays, and obsolete inventory.
