    • Optical power refers to the total optical output power collected by integrating sphere;
    • The measurement errors of forward voltage, peak wavelength and radiation power are ± 0.2V, ± 3nm and ± 10%, respectively. The increase of injection current will lead to temperature rise, The light attenuation of LED lamp beads will be accelerated, and the service life will be shortened; when the LED lamp beads are tested or used beyond the above limit values, the reliability of the device may be affected and permanent damage may be caused.
    • It is recommended to provide a good cooling environment or cooling system to obtain the best effect.
