You get What You Pay For

If installed correctly per the included instructions this unit performs as expected no issues. Love it.

Well made product

I have nice landscaping and these units plus the lights just makes our yard beautiful at night.

Perfect for what I wanted

Has been working great for months now. Running 8 spots and 6 walk way lights without overheating. Great product.

They work great

I bought this to replace a transformer that burnt up in 8 months not one time but twice will never buy a transformer from another brand. This seems to be working perfectly.


I love it. I been using it for 1.5 years now and so far never gave me any trouble. I would really recommend this.

Manufacturer's Testimonials

  • I have used several ABBA products from transformers to pool lights and I am beyond happy with them. Besides their wonderful products, they have one of the best customer supports in the industry and through troubleshooting, my issue was easily resolved. I highly recommend them to everyone.

  • I'm inspired to leave the first testimonial I've have ever left in my life. I did a ton of research and still I went through four different light manufacturers before I found ABBA Lighting. I couldn't be happier with the results. Keep up the quality of your products and your timely customer service!

  • When buying this light, I was expecting a small light. This is by far, much larger than you get at a store. As far as brightness, wow, it is bright. A foot and a half from the flag pole. it will light a flag 30 feet up. As you can see in the picture the massive size of these lights. It has the design to last.
