The price and performance of this product is great. I've installed many units with the requested outcome of 12v transformer. This one seems to produce strong 12v. Yes, I used a digital meter that gave me a 12v reading, however the wattage was definitely stronger than many others of different brands. I purchased two, the first one was for Two LED, multi-color pool lights (The Big Ones). They look great. The second was the same 12v, led but smaller niche less lights. They too looked better from the power supplied by this transformer than the sponsored pool transformers. I will use this one until they build something better at a better price.Great product!
