Light, water and nutrients are essential for plant growth. Modern development in the area of a protected ground confirms that today, lighting technology plays a huge role in production efficiency of plants, vegetables and flowers. Parameters of the lighting system affect the quality indicators of seedling production, the timing of its distillation and the yield. For artificial lighting of plants in greenhouses economy of Russia is currently the most acceptable metal halide and high pressure sodium lamps, by which continues growing season of plants, improving control over their growth. Research study and practice of crop showed that the wavelengths of radiation high pressure sodium lamps, which are concentrated the greatest part of radiation energy, coincide with areas of maximum sensitivity of plants. For the basic processes of photosynthesis, plants use the entire visible range of light radiation, but in the blue and red spectral regions, their sensitivity decreases. The emission spectrum of sodium lamps do not contain harmful ultraviolet rays and the power of photosynthetically active part of the radiation is sufficient for normal growth and development of plants. High pressure sodium lamps are one of the most efficient light sources, because have a high luminous efficacy (140 lm / W) and the radiation efficiency (300 mW / W).

When growing svetokultury require high light levels and long cycle . Costs electricity for irradiation plants constitute a significant part of production costs and therefore the effectiveness of irradiation facilities is becoming an important economic factor. The main criteria of efficiency lighting technology is an effective source of light and the efficiency of the optical system. The most suitable light source for large scale crops are professional slr high pressure sodium lamps type DNZ-100, DNZ-150, DNZ-250, DNZ-400, DNZ-600. By a special rotating base that allows you to rotate the mirror bulb in the lamp axis and direct the light beam in the desired direction, mirrored sodium and metal halide lamps can be installed in the usual traditional lamps for sodium and metal halide lamps.

Reflector lamps represent an excellent combination of power light with a spectral range of high-performance, long life and an optical system with excellent light distribution, high stability of flux throughout its entire life. Advanced design of cap lamp mirror eliminates the case of violation of the electrical contact in the socket and lamp holder lead them out of order, occur in previously issued mirror lamps. Great contribution to the lighting efficiency of irradiation facilities makes the optical system reflector lamps, consisting of a highly mirrored surface deposited on the inside of the bulb. The optical system of the lamp, ensures high efficiency of the luminous flux of at least 95%. Due to the hermetic isolation from the environment, the absence of multiple reflections, the optical system does not lose the reflection properties and does not require additional cleaning with a life. Extremely long lifetime (up to 32 000 hours) and almost constant over time the value of the luminous flux made slr sodium lamps the most efficient gas-discharge lamps High pressure in covering greenhouses, which favors the development of plant, stimulates an increase in their volume and number of leaves, flowering and vegetative growth.
