3 indicators correctly selected energy-saving lamps

One energy-saving lamp is twenty or thirty yuan, and one incandescent lamp is only two or three yuan. Many consumers will purchase lamps based on the price, but they do not know how to use energy-saving lamps to save more money. Because high-quality energy-saving lamps are five times more energy-efficient than incandescent lamps, their lifetime is five times that of incandescent lamps. Selecting high-quality energy-saving lamps should begin with three indicators.

Indicator 1 phosphor coating

High-quality products use rare earth trichromatic phosphor coating, which has high luminous efficiency, high color rendering index, good thermal stability, and long service life. A high-quality energy-saving lamp is equivalent to the use time of 3 to 8 inferior energy-saving lamps, and the cost is 30 times that of common halogen powder.

Inferior products may be mixed powder of halogen powder or rare earth tri-phosphor phosphor mixed with halogen powder. Its luminous efficiency is 30% lower than that of rare-earth tricolor phosphors, low color rendering index, poor thermal stability, severe light degradation, and short lifetime. Cheap, especially not suitable for use in thin tube fluorescent lamps.

Reminder: Lamps with poor color rendering will not only make the makeup color, but also cause children's color weakness. With good color rendering, the objects seen are closer to the color of the noon sun.

Indicator 2 Electronic Ballast

High-quality products are manufactured through reasonable circuit design and selected high-quality electronic components. They have small heat output, high power factor, and no flicker at the time of operation, which protects the user's eyesight and physical health. In order to save production costs, counterfeit and inferior products can be assembled and manufactured by outsourcing low-quality electronic ballasts. The quality cannot be guaranteed and the failure rate is high.

Reminder: The high-quality electronic rectifier has a fast start-up time and less strobe light, thus eliminating power loss and glare, saving about 30% of electricity, and better protecting eyesight.

Index 3 plastic parts

High-quality plastics have good heat-resistance, flame-retardant and insulation properties, and are resistant to cracking, easy printing, and white discoloration. In order to reduce costs, counterfeit and inferior products use medium- and low-grade plastics, which are brittle, easy to crack, and easily discolored, posing a potential safety hazard.

Reminder: The quality of plastic parts is stable and safe. The heat resistance and flame retardancy of inferior products do not meet the standards, and their service life is short.
