Low temperature horticultural light apparatus

A horticultural light apparatus, comprising:

• a hollow, cylindrical glass tube having a first open end and a second open end,
• two opposed open ended caps, each cap adapted to be affixed to the first open end and the second open end of the glass tube, respectively, the two opposed open ended caps and the glass tube forming an elongated horticultural light apparatus;
• a mounting bracket adapted to mount a lightbulb within the tube such that the center point of the lightbulb diameter is positioned at approximately the diameter center point of the glass tube, the glass tube absorbing a minimum amount of light emanating from the lightbulb thus enabling substantially all of the emanating light from the lightbulb toward the plants to be absorbed by the plants for increasing plant growth;
• the diameter of the tube being of a size sufficient for enabling the free flow of air through the elongated horticultural light apparatus and over the lightbulb thereby reducing the heat generated by the lightbulb from being absorbed by the plants;
• means for reflecting the light from the lightbulb in a direction toward the plants.
