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. 1. A method of cooling a horticulture lighting fixture , the method comprising the steps of:{'b': 200', '205', '235', '245', '220', '100', '220', '830', '220', '830', '2', '235', '245, 'providing said horticulture lighting fixture having a housing with a downward facing bottom opening , a first duct , a second duct , a housing interior , a reflector captured within said housing interior , and a socket extending through said housing interior and oriented so that said socket holds a lamp bulb in a substantially parallel orientation in relation to a longitudinal axis extending between the first duct and the second duct ;'}{'b': 2', '830', '2', '102', '100', '205, 'installing said lamp bulb into said socket so that operation of said lamp bulb illuminates surfaces of a reflector exterior side of reflector to reflect light downward through opening ;'}hanging said horticulture lighting fixture at a predetermined height above plants to be grown thereunder in a plant growing environment;{'b': '235', 'attaching a fan to said first duct ;'}{'b': 235', '245, 'energizing said fan so as to flow cooling air between said first duct and second duct ;'}{'b': 2', '205, 'energizing said lamp bulb so as to reflect light downward through opening ;'}{'b': 235', '245', '220', '101', '235', '245', '102', '101, 'removing heat from said fixture by flowing cooling air between said first duct and second duct through a ...
