Love my new lighting. The install team was very professional and knowledgeable. My install was completed earlier than first communicated. I couldn't be more happy with the product and the service.

We love Trimlight's service and highly recommend them to all of our friends and neighbors. They promptly came out for estimate, fast installation and great after-installation customer care. The lights are beautiful, great warranty and price. It's a great investment.

I absolutely LOVE my Trimlight lights! We got it originally 5 years ago for Christmas so we wouldn’t have to put up & take down lights but we use them all year for every holiday, sporting event, birthdays, and even as security lights. I’m so glad we went with Trimlight and their life time guarantee. We have been nothing but happy with our purchase even with the initial investment, it has been totally worth it!

Great service from sales to installation crew. The app is convenient and simple to use. I enjoy each holiday, birthdays, game days now with special designed lighting at the click of a button. I highly recommend Trimlight lighting.

We love our new lights installed by Jake and Dillon! They were very professional and kind to my kids who enjoyed watching them work. I would highly recommend TrimLight and this team specifically when you are ready to get permanent lighting!!

These guys are the real deal! The quote was quick and easy, and all my questions during that process we're answered! Installation was also a breeze. Everyone I've spoken to has been so great! I am happy with our lights and having fun with them! We were put on the schedule super quick!

Priced fairly. They work fast and the end result is amazing. Lots of features in the app that make the lights that much more useful. We got the 2 zone system for front and back and that was the way to go. I know there are a lot of permanent light companies out there, but you won't be disappointed if you go with Trimlight.

Trimlight was great. The company was patient with me while we decided what I needed and wanted. The lights were installed efficiently in one day ahead of schedule even. They look great and hopefully we will have years of enjoyment ahead of us with the lifetime warranty.

OMG! We LOVE our new lights. They are perfect! Trimlight did an amazing job with the install, the tutorials, and the product can't be beat! We got quotes from multiple companies and these guys were right in line but are local and have a lifetime warranty. We recommend 100 percent!

Why did I not do this sooner? What a neat product this is and great people to deal with, from Kelsi and Jessica answering all my email questions with quick responses to the very professional install team that did a seamless install in a short amount of time and respected my house and landscaping while working in 20 degree weather. Thhe tutorial at the end of the install was self assuring that even a guy lacking in technical skills can navigate the simple program. Can’t wait to add on into the backyard for summer time fun.
