Advantages Of LED Grow Light Compare With HPS Lamp

Grow lights are used in applications where there is either no naturally occurring light or where supplemental light is required. Horticultural LED systems and the spectral science they have made possible have already revealed some amazing effects, including using light alone to create bigger yields per plant; producing more marketable crops overall; and changing the wavelength of light to change the flavor of foods. For these reasons and others, including the ones detailed below, LEDs are on their way to replacing legacy lighting systems in many new and newly renovated growing operations. In addition, LED technology is popular for scientific application to get the best results with high-efficiency photosynthesis and healthy growth duration.

Avoid High Temperature Damage To Plants

High temperature damage, is a plant physiological injury caused by too high temperature. This will lead to deterioration of plant protein, damage of biofilm structure, disorder of metabolism in the plant, and abnormal phenomena such as leaf burning, plant wilting and flower falling off.

According to the law of energy conservation, it is found that the ability of LED and sodium lamp to convert electric energy into light energy and heat energy is different. Using the same energy, the LED plant growth lamp as the cold light source will produce more light and less heat, while the sodium lamp of the hot light source will produce a lot of heat and less light while lighting.Therefore, compared to these two lights, LED plant growth lamps not only save energy, but also convert more energy into light energy, providing effective radiation for plants, and effectively avoid plant “high temperature damage” and help users reduce planting risks.

Longer Service Life

LED uses solid semiconductor chip as the luminescent material, and the light decay is small. The sodium lamp is used to generate arc between the electrodes between the two ends of the arc tube, and its life expectancy is shorter than that of the LED plant growth lamp.

Rich Wavelength And Good Light Filling Effect

As an important factor of plant growth, light plays a very important role. It is found that the spectral energy distribution of sodium lamp can be roughly divided into red orange light, yellow green light and blue violet light (a small amount). The LED plant growth lamp can emit monochromatic light with narrow light wave, such as red, green, blue, orange, etc., and these monochromatic light can be mixed. For example, the mixed wavelength LED light source can promote the growth and development of lettuce, basil and other seedlings and roots, shorten the flowering and fruiting cycle of plants, and increase the accumulation of sugar and starch in sugar beet; The red and blue spectra with different proportions can meet the requirements of different stages of plant growth, coloring, flowering and fruiting.

To sum up, LED grow light has more advantages than sodium lamp in performance, service life and effect, reduces the cultivation cost, and is more worthy of consumers to buy.
