Horizon Lighting Systems does a wonderful job with all of our lighting. They are reliable, professional and keep my lights glowing beautifully especially at the Holidays! Many thanks to Brian and his crew for making my "house" look like a "Beautiful Home". I would highly recommend them for both your landscape and holiday lighting needs

Prompt, responsive, professional service resulting in a beautiful holiday lighting experience that highlighted the architectural lines of our house. BTW, we had Horizon install our landscape lighting as well. We'd recommend Horizon Lighting Systems to anyone searching for a reputable lighting company for landscape and/ or holiday lighting...

We have been very satisfied with Horizon's work performed and professionalism over the past 8 years in two homes. Annual Holiday lighting as well as the entire yard. In our new home, Horizon has upgraded 55 LED "can lights" around the home plus 30 low voltage lights in our back ravine - then integrated them with our Crestron lighting system. A pleasure to work with.

They worked hard to diagnose our existing landscaping lighting, which wasn't all powered or working. They rewired, replaced, and removed parts, which redistributing the remaining lighting to still look good. I appreciate the time and effort they took on the job to help me get my home ready to sell.

Everything happened around my schedule -- none of this having to keep the whole day open to work around their schedule instead of mine. They were very professional, friendly and courteous.

We really enjoyed working with Horizon, they did a wonderful job on our house. We also loved the demo they gave us before they came to install the lights, it let us see what we were getting and how are house would look lit up. Thanks again we loved your work
