Ironsmith Lighting Products150 Watt Dimmable Halogen Lamp Transformer - Metal & Plastic Material, Halogen, Xenon, Krypton Type Light Bulbs Support - Short Circuit Protected with Auto Restart

So far it works as well as the old unit which lasted 25 years. It was a tight fit because the dimensions were inaccurate. The real dimensions are 4.33" L x 1.81" W x 1.18" H (110 mm L x 46 mm W x 30 mm H).

Replaced 22 year old transformers for the low voltage lighting in our home theater that were getting a bit tired. These were an instant improvement. I hope they last as long as the ones they replaced.

Perfect

Works perfectly

DOA out of box , requested a replacement, received another DOA out of box.

I had to figure out how many watts I would need for seven puck lights. Our lights are 12 watts, so I needed a transformer that would take at least 84. I opted for 100 watt transformer. After that, my husband replaced the old . Works great.
