Abstract
In a chamber for cultivating plant growth, a plurality of light fixtures are employed, each containing a high intensity discharge lamp. The bulb of the lamp serves as an inner transparent wall and a globe functions as an outer transparent wall. In the space between the bulb and globe water is caused to flow in order to remove unwanted radiation and heat generated by each lamp before the radiation is transmitted into the growth chamber.
