Color TemperatureColor temperature is conventionally expressed in kelvins, using the symbol K, a unit of measure for absolute temperature. Color temperatures over 5000 K are called “cool colors”, while lower color temperatures (2700–3000 K) are called “warm colors”3000K-Warm White;4000K- Netural White;6000K-Cool White What’s the different between 2/3/4 wires trackAll our track spot light is suitable with EUROPEAN standard track.2 wires track is single circuit,with a null line and a live line.3 wires track is single circuit,with a null line and a live line and a ground line.So to be same as single circuit,3 wires track is safer than 2 wires track.4 wires track is 3 circuits,with a null line and 3 live lines.If wanna control 3 groups led track light,you can choose 4wires track rail.
