3rd party gaming keyboard backlight button?

So i just purchased a 3rd party CM Storm Devastator keyboard and it is compatible for both PC and Mac, it is a pc keyboard but i just remapped the keys so its all good, but the backlight toggle is on the SCROLL LOCK button. For some reason when I press the SCROLL LOCK button it doesn't turn on. When I plugged the keyboard into my sisters's PC (eww pc) the SCROLL LOCK button for the backlight worked perfectly. Is there a separate command for Macs to activate scroll lock? Thanks.
