If the wavelength change, stimulate phosphor ability to drop, luminous efficiency will be lower.
For whether they contain blu-ray in the lamps and lanterns, we can take when buy spectrometer to measure the lamps and lanterns of the light spectrum, if the intensity of blue light than the sun's blu-ray strong many, don't buy that.
LED eye classroom light out of the light should be uniform, soft, the brightness is appropriate, light area is moderate, does not cause dizzy, for our eyes can't see, the feeling of dazzling, so you can rest assured purchase.
