## Customer Reviews

### ⭐⭐⭐⭐⭐ Reliable Power Supply and Easy to Use
*by I***F on January 31, 2025*

I needed a dependable power supply for my LED lighting setup, and this one works perfectly It delivers consistent power with no flickering, and the 45-watt capacity is great for multiple LED stripsThe removable AC cord makes installation more flexible, and the compact design helps keep everything neat and organized The build quality feels solid, and it does not overheat even with long hours of useThis product is a great value for money and offers excellent functionality If you are looking for a high-quality and reliable LED power supply, this is a great choice Would definitely buy again

### ⭐⭐⭐⭐⭐ Heavy, dims very smoothly with full range, silent, and worth the money
*by O***N on April 20, 2025*

If you’re going to spend the time to install this, or pay someone to, then there’s no point in saving $20 or $40 on a cheaper power supply. Just get one of these Armacost ones or it will probably cost you more in the long run.These operate perfectly and they’re heavy, indicating that they might actually survive at their maximum rated output unlike manufacturers making dubious claims about what they can do with half as much copper.24V is much better than 12V because half the amps are required for the same wattage. That means less heat, less power loss per unit of strip/wire length, and longer runs of strip and wire become possible. So I’d use 24V whenever possible.

### ⭐⭐⭐⭐⭐ Worked as expected, installed easily and  no issues after using device for a while now..
*by C***N on April 13, 2025*

Purchased for a Under cabinet lighting project and installed the power supply in the attic with a dimmer switch. Unit installed easily and works well. The two legs of lighting worked well for my particular install. Unit seems to be built well and is of a solid design. Between this power supply and the selected dimmer it works well.
