They are only low voltage connections (10v) so not really an issue from a safety perspective.
Personally, I have built an Arduino micro controller to control, amongst other things, my lights - I probably would not have gone done the LED light track if I couldn't have sunrise/sunset type effects as I don't like subjecting my fish to lights full on/lights totally off. LED's are worse than MH's - at least the MH's take a while to warm up and reach their maximum intensity.
Also, you will need an adaptor for the 10v power supply - might be easier to get this removed from the kit and buy one locally.
