A connection mechanism on an LED lighting fixture for connecting a first element of the LED lighting fixture to a second element of the LED lighting fixture, said connection mechanism comprising:

• a plurality of bayonet tabs configured on one of said first element and said second element;
• a plurality of bayonet slots engageable with said plurality of bayonet tabs, said plurality of bayonet slots configured on one of said first element and said second element that does not contain the plurality of bayonet tabs, wherein said plurality of bayonet tabs are aligned with said plurality of bayonet slots, subsequent to which, said first element is partially rotated with respect to said second element to facilitate the reception of said plurality of bayonet tabs within said plurality of slots, thereby providing a connection between said first element and said second element of the LED lighting fixture;
• wherein said plurality of bayonet tabs have:
• a first portion having a partly tapered profile;
• a second portion extending from said first portion and having a rectangular profile;
• and
• a third portion extending from said second portion and having a rectangular profile, wherein the width of said third portion is greater than the width of said second portion;
• wherein the LED lighting fixture includes a hood and an LED housing;
• wherein the second element is the hood of the LED lighting fixture, the hood having an internally threaded aperture for pendant mounting to external threads of a downwardly extending conduit;
• and
• wherein the first element is an adaptor having a lower end coupled to the LED housing and extending from the LED housing;
• and the adaptor has an upper end adapted to be received within the hood.
