Increase luminous flux
Increase luminous flux
Increase color temperature
Increase the proportion of powder on the impact
Color temperature decreases, color rendering index increases, and light decay decreases
Increased color temperature, reduced color rendering index
The color temperature increases, the color rendering index decreases, and the light fades rises
