Nowadays,LED panel light is very popular in office.When we say panel light with high power factor( high PF),actually it means the power factor of the lamp's driver is high(usually PF>0.9). I am often told by customers"i want high PF LED panel light." Actually there are two kinds high power factor driver,one is with flash,the other is non flash. Very often, clients will ignore the latter.From the perspective of protecting eyes,if you choose LED lamp with high power factor ,it is better to use high power factor and non flash driver. Otherwise,using LED lamp with low power factor driver is more healthy to our eyes than using LED lamp with high power factor driver only.
