A outdoor lighting fixture includes an enclosure, a heatsink, and an end-cap. The enclosure includes a cabinet and a cover that enclose control and power circuitry to provide power to illuminate a light source. The cabinet further includes an attachment face, and the extruded heatsink can be coupled to the attachment face. The extruded heatsink includes sides, a discontinuous plane of material formed with sides of the heatsink to provide a recessed mounting tray, and heat-conducting fins extending from the plane of material. The light source, which can include an LED light source, is coupled to the heatsink. The extruded heatsink can be coupled at one end to the attachment face of the cabinet at a position such that a space remains between the plane of material and a bottom edge of the attachment face, to permit water to drain from between the heat-conducting fins of the extruded heatsink.

A lamp device includes a lamp seat, a lampshade having an inner inclined surface and defining an opening, and a securing unit having a cover shell and a plurality of locking mechanisms. The cover shell is disposed in the opening and connected to a mounting plate of the lamp seat. Each locking mechanism has a locking member having a ring portion that is disposed rotatably in a respective one of receiving notches of the cover shell, and an arm portion that is co-rotatable with the ring portion between an unlocked position, and a locked position where the arm portion is disposed outside of the respective one of the receiving notches and abuts against the inner inclined surface, such that the lampshade is fastened to the lamp seat.
