The value of HSBType.red (also green and blue) contain the percentage of the color. If you want the value you have to multiply it by 2.55. So you have to change the rule to:

var ColorHSB = LEDStrip_Test_Color.state as HSBType
val red = (ColorHSB.red * 2.55).intValue
val green = (ColorHSB.green * 2.55).intValue
val blue = (ColorHSB.blue * 2.55).intValue
LEDStrip_Test.sendCommand("{\"color\": {" + 
	"\"r\": " + red + "," +
	"\"g\": " + green + "," +
	"\"b\": " + blue + "}}")
