Our Integral Lighting 12vAC LED is fully dimmable. Keep in mind that reducing the voltage to an LED does not change the color (warmth) of the light output as in an incandescent installation. LEDs are designed to emit the same color at all points of voltage.
If you need to alter the color output we have various options. In particular, our IL300 and IL600 Series emits 2400K, the warmth of a candle light. We also offer filters for our other fixtures which can create the mood and feel you are looking to achieve.
