LEDs offer numerous benefits due to possibility for different operation modes. Optical parameters of light emitting diodes strongly depend on the regime of operation that you choose. To receive maximum average power we recommend using pulse modes with duty cycle 50% (quasi-continuous wave mode) or 25%. This mode provides signal modulation at certain frequency and allows obtaining higher output intensity than in case of using hard CW (continuous wave) mode.
