What if the LEDS on a reef tank were set to flash at a rate too fast for the human eye to see? Many LED
flashlights already do this to save power. I've heard that the battery can last as much as 25% longer by flashing the LEDS beyond 10 hertz so that the eye cannot see the flashing. If you have an array of 50 three watt LEDS, one could flash them so that only one LED
is on at any given moment, but would look like all of the LEDS are on at the same time and the entire array would consume only 3 watts rather than 150 watts. While the human eye would not see the flashing, would this adversely effect the corals?
Could all of the pumps also be put on a frequency so that only one device is on at a time and therefore only consumes the power of the highest wattage item of the whole reef setup?
Thanks for satisfying my curiosity,
