Interesting article that I link to below about the difference between AC and DC. Swimming pools and spa's always need 12 Volts of AC power. Most people hear 12 Volts and immediately think of DC which is used in cars and also outside landscape lighting. If you hook pool LED's to 12V DC, sometimes they work, but not correctly. If you experience strange problems with your pool lighting, always check to see if it is AC or DC.
We offer several different very reasonably priced pool and spa transformers at the links below:
