When the T5 lamp is used, it will produce some electromagnetic waves and microwaves. Contains mercury and may have ultraviolet leakage; And many Chinese workers have suffered mercury poisoning from making energy-saving lamps. Light decay, after a long time, the luminosity will be lower than the new product, most of them can not be dimmed, and it is not suitable for dimmable brightness lamps. It is not suitable for occasions where frequent switching is required, and LED or CCFL lighting is better in these occasions. Low color rendering: incandescent and halogen lamps have a color rendering of 100, which is perfect; Most of the color rendering of energy-saving lamps is between 80 and 90, of course, the price is its advantage, and the price ratio of the other two lamps is undoubtedly a huge advantage.

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.
