Heat shield for agricultural light bulb

An air-cooled light comprising:

• a high intensity discharge light bulb secured in a socket;
• a cylindrical transparent sleeve surrounding said high intensity discharge light bulb and said socket, said cylindrical transparent sleeve having opposing ends;
• two sealed end plates, each being attached to one of the opposing ends of said cylindrical transparent sleeve, said socket being attached to one of the two sealed end plates;
• a first hose flange having one end attached to one of said sealed end plates and an opposing inlet end;
• a second hose flange having one end attached to the other of said sealed end plate and an opposing outlet end;
• a hose circumferentially attached to the inlet end of said first hose flange and the outlet end of said second hose flange, thereby forming a closed path for moving air through said cylindrical transparent sleeve;
• and
• a temperature actuated disconnect switch disposed within said cylindrical transparent sleeve, said disconnect switch adapted to disconnect an electrical power source from said high intensity discharge light bulb when temperature inside of said cylindrical transparent sleeve reaches or exceeds a predetermined temperature.
