Claim 20:
21. The apparatus of claim 20, wherein the one or more LEDs comprise multiple groups of LEDs, each group of LEDs comprising one or more LEDs, and wherein the controller is further configured to, after determining that the measured intensity is outside the threshold window and before adjusting the current:
sequentially drive each group of LEDs; and
for each group of LEDs, determine whether a power output of at least one of the LEDs in the group of LEDs is less than an expected power output; and
if the power output of the at least one of the LEDs is less than the expected power output, then the adjusting of the current driving the one or more LEDs is based on the power output of the at least one of the LEDs, to compensate for the power output of the at least one of the LEDs; and
if the power output of the at least one of the LEDs is not less than the expected power output, then the controller is further configured to adjust a UV transmissivity value of the fluid, and wherein the adjusting of the current driving the one or more LEDs is based on the adjusted UV transmissivity value, to compensate for the adjusted UV transmissivity value.
