Medium color temperature
According to GB7793-20 10 "Hygienic Standard for Daylighting and Lighting in Primary and Secondary Schools", classrooms should use light sources with a color temperature of 3300 K-5500 K ... Professional LED educational lighting is mostly 5000K warm white light, which is comfortable and natural. However, the color temperature of traditional T8 fluorescent lamp and ordinary LED lamp is often above 6500K, which belongs to cold white light. Long-term use may have adverse effects on students' eyesight.
No stroboscopic danger
Strobe is a big killer that affects eyesight and learning efficiency. Traditional T8 fluorescent lamps and ordinary LED lamps have serious time-frequency flicker when they are started or the voltage is unstable. Studying in this environment for a long time is easy to cause visual fatigue and reduce learning efficiency. And professional LED educational lighting, light stroboscopic less than or equal to 3.2%, far lower than the first two, can better protect students' eye health.
