I had mine created custom by a LED strip supplier over here in Europe, so i could use them in water (IP68). You could specify not only the length of the strip itself but also the length of the control/power lines to the strip. The power supply can be in dry area (house/barn) together with the controllers (i just bought a couple of WIFI RGB controllers from Mi-Light, but these can be bought from different sources). if you connect ST compatible controllers it should wordk. Mine actually work via a Domoticz Gateway which i already had and which had build in support for Mi-Light)…
