An illumination system includes a gas containment vessel configured to contain a gas. The illumination system also includes one or more pump sources configured to generate one or more pump beams. The illumination system includes an ozone generation unit including one or more illumination sources. The one or more illumination sources are configured to generate a beam of illumination of an energy sufficient for converting a portion of diatomic oxygen (O.sub.2) contained within the gas containment vessel to triatomic oxygen (O.sub.3). One or more energy sources are configured to ignite the plasma within the gas contained within the gas containment vessel via absorption of energy of the one or more energy sources by a portion of the triatomic oxygen, wherein the plasma emits broadband radiation.

The present technology provides a high-pressure sodium lamp lighting device that reduces occurrence of the acoustic resonance phenomenon. A high-pressure sodium lamp lighting device of one aspect of the present invention comprises a high-pressure sodium lamp of arc length AL within the scope of 142.8 mmAL167 mm. The lighting device also includes an electronic ballast configured to supply a high frequency AC voltage to the high-pressure sodium lamp. A lighting frequency of the electronic ballast is a frequency that avoids a first and a second acoustic resonance occurrence bands f1 kHz and f2 kHz determined based on equations from an arc tube inner diameter D mm of the high-pressure sodium lamp. The equation for f1 is a range of f1min to f1max=(7.4D+130) to (8.3D+156). The equation for f2 is a range of f2 min to f2max=(11.5D+200) to (10.0D+197).

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.
