Yes. Your typical landscape lighting installation operates on 12 volts and is powered by a magnetic transformer. Integral Lighting is compatible with existing 12vAC installations. Be sure to consult your transformer rating to be sure that you have enough capacity to power additional lighting fixtures. If not, consider the addition of another transformer or increase your current power supply.
All of our energy efficient LED products were designed specifically for use with both magnetic and electronic transformers and require no additional drivers or electronic components.
