Hi John,I see . It's ok with leds . We did pulse testing on such leds.But it will increase the decay of light a little bit . You can try an samples .
Frequency is 1.0hz .1 time per second. We tested 3 monthes . And if leds ok . then we use the chips.
Hi John,No . 30mA is the max current .150mA will burn the leds.If need 150mA . You should use 0.5W
So pulses at a frequency of 100Hz or more actually appear brighter to the eye than a continuous light of the same average intensity.
So running the LED for half the time only loses a quarter of the perceived brightness, and you could go down to 1:7 ratio before losing half the perceived brightness.
