A lighting device includes a support structure formed from a thermally conductive material such as aluminum. The support structure or extrusion has a channel for receiving and retaining a circuit board with a plurality of light emitting diodes (LEDs) disposed thereon. One or more fins adapted for dissipating heat produced by the LEDs may be disposed on the support structure. The support structure may also include one or more retaining members for retaining one or more optical elements in relation to the LEDs and a support tray for holding a power supply.
