Claim 15:
16. A portable system for controlling an environment in a closed volume, comprising:
a light source;
a first temperature sensor positioned to gauge an internal temperature inside the closed volume;
a second temperature sensor positioned to gauge an external temperature outside the closed volume;
a fan;
a control circuitry adapted to receive inputs from said first temperature sensors said second temperature sensor and from a user, and to adjust an intensity of said light source and to increase and decrease a speed of said fan as a result thereof to control the temperature of the light source and the temperature in the closed volume;
a housing said light source, fan and said control circuitry; said housing adapted to be positioned at a top of a structural element defining a closed volume with a lower surface of the housing in communication with the closed volume and an upper surface of the housing in communication with air outside said closed volume, said fan controlling air flow between said lower surface and said upper surface and wherein said housing adapted to be moved from the closed volume to another; and
a filtering cassette located in a path of said air flow.
