4 Pcs LED Transformer Replacement Class 2 Power Supply for Christmas String Light Inflatable Decorations LED Controller IP44 Waterproof Low Voltage Transformer US Power Adapter for Home (12V15W 1.25A)

BoltLink lights were popular on Amazon, and then they seem to have disappeared, and it was probably because the controller/transformer they used was not waterproof. So after using for one season, they all started shorting out (and BoltLink probably got a lot of returns because of that). But it was just the controller/transformer that was bad the strings of lights were fine. Finding a replacement controller/transformer was a bit tricky, but these work great. We use a lot of outdoor lights and we really appreciate that these controllers allowed us to use our BoltLink lights without have to buy a new set.

These transformers replaced ones that had stopped working. They were perfect. Second time I ordered them

All 4 power supplies did not work with LED lights. It was the exact model, amperage and voltage needed. It connected properly to the female connector, but no joy. I took another adapter from a different light to verify that the light was good, it was. The other adapter was the exact model, same input and output values. I saw both good and bad reviews on the product. Guess I was just one of the unlucky ones. Thankful that we have Amazon return policy.

I thought I was going to lose my entire prelim tree but fortunately this was built in a plug. Easy to fix👍

The media could not be loaded.  The transformers are flickers and not steady. Doesn’t match my other LED trees. It does stand out though.

Work as it should just down screw on

Cannot just turn on and use it. Tried to replace a “dumb” transformer that just turned on. It worked the first time I plugged it in, then stopped working as it changes its output each time the power cycles. My original LED string is just white and not dimmable or multicolored. Don’t try to save your money buying a transformer and just buy a whole new string guaranteed to work.

Wen to set up the halloween blow-ups and realized I stole the power supplies for the christmas blow-ups. I did not feel like breaking out the christmas stuff so just ordered these. They work great, we have a had few rains now and they are still working, so i cannot complain.
