An air cooled horticulture lamp fixture for growing plants in confined indoor spaces. The fixture seals the lamp and heat generated by the same to a reflector interior. Flow disruptors create turbulence in a cooling chamber thereby enhancing thermal transfer into a cooling air stream that flows over and around the reflector's exterior side thereby convectively cooling the lamp using the reflector as a heat sink. The lamp is effectively maintained at operational temperatures and the fixture housing is insulated from the hotter reflector by a gap of moving cooling air, allowing improved efficiencies of the lamp bulb in confined indoor growing spaces.

An air cooled horticulture lamp fixture for growing plants in confined indoor spaces. The fixture substantially seals the lamp and heat generated thereby to a reflector interior. A flow disruptor diverts moving air away from an aperture in the reflector through which a lamp bulb socket protrudes into the reflector interior, and the flow disruptor creates turbulence in a cooling chamber thereby enhancing thermal transfer into a cooling air stream that flows over and around the reflector's exterior side thereby convectively cooling the fixture using the reflector as a heat sink.

An air cooled horticulture lighting fixture for growing plants in confined indoor growing spaces having a cooling chamber between a first duct and a second duct and an internal ballast within the cooling chamber such that air flowing between the two ducts flows through the ballast components to cool the ballast, and also removes heat from operation of the lamp bulb. An access cover is provided for easy removal and replacement of the ballast board.
