Light setting question

[oliverw953]

Hi all

I have two tmc photons on my tank, I'm just wondering what the florescent parts means/does. I have it on low but don't actually know what it is.

thank you

Looks to be the spectrum of weather effects so instead of changing the brightness it goes through a wide range of spectrums over some time period. The low/med/hi is probability, or frequency that it will do this.
