At present, the market is mainly used for halogen lamps, T5, LED lamps in fish tanks; The advantages of halogen lamps are good color rendering, full spectrum, and good for the growth of coral plants. Halogen lamps also have definite shortcomings, halogen lamps consume electricity, short life, low luminous efficiency, the most important is easy to produce ultraviolet rays, ultraviolet light referred to as UV. What many people may not know is that UV is divided into UVA and UVB. UVB at most makes people sunburn and tan; Although UVA is weak, it has super penetration, even accounting for more than 95% of ultraviolet rays, which can cause a variety of skin diseases, which is also a problem that many aquarists with children at home are worried about. Grow Light 640W , Strip Light , Room Light , LED is used as a light source for indoor lighting, and there are still certain problems with lighting effects. The efficiency, color and service life (attenuation of light) of individual luminaires, as well as the quality of illumination, are not ideal. Although LED illumination is very high and energy consumption is very low, this does not mean that the efficiency of LED lamp light is high, because its overall lighting quality is not high. In addition, LED lighting fixtures need to avoid too strong glare LED grow light features and introduction. Only when the temperature is suitable LED lighting fixtures can be very long, once made into poor quality lamps, in high temperature and closed environment, the lighting effect will drop sharply.

What are PAR and PPFD in LED grow lights

One way to visualize PPFD is to imagine that the sun is “pouring” light onto plant leaves. As the sun shines light on plants, their leaves are gathering energy.

PPFD is a measurement of the amount of light (photons) that the sun “pours” onto plants over time. PPFD is an important indicator because it helps growers accurately measure the light intensity of photosynthesis in the canopy. This is also important because lights that are too close to the canopy can cause burning, bleaching, growth retardation, or discoloration.
