There is also an issue of the light spectrum emitted by LEDs.   The LED light spectrum puts more emphasis on blue light, than, say, incandescents especially, and even halogens.   There's a potential audio/radio frequency issue as well as an issue related to visual light.

Humans are affected by the blue light more than most people realize.   It's quite possible that the blue light is somehow disrupting whales as well.   (Do whales have melatonin cycles too?)

Perhaps a question for David Suzuki and co?
