Abstract
A luminaire may include an input connection that receives AC line voltage, one or more chains of LEDs, and one or more drivers for driving each chain of LEDs, all within a housing, which may be in the form of a canopy. Each chain of LEDs may contain at least 36 LEDs connected in series. Each LED may have a power rating of no more than 1 watt and may be oriented to direct light outside of the housing when illuminated. Each driver may receive power that is extracted from AC line voltage connected to the input connection and provide one or more outputs that drive at least one of the chains of LEDs.
