    Awesome quality recessed lights and DIY friendly

    Bought these to replace my old flickering recessed lights. So far, they're exceeding my expectations! The warm dimming feature creates a cozy vibe at night, and installation was a breeze – literally took me 2 minutes. They blend seamlessly with the ceiling too! Highly recommend.

    A Bright Upgrade

    I recently upgraded my lighting to LUSA, and what a difference it's made! The moment I unboxed my lights, I could immediately tell that they were higher in quality compared to what I had before, from weight, color and design. The matte finish on these lights really adds a subtle, luxurious touch that I love, too.

    Installing them was very easy, just took a couple of minutes. I chose the round trim option, and the warm color they emit is just right—cozy and inviting without harsh glare. Plus, now all my lights match in color, which makes a big difference in how my rooms feel. A plus that the lights and packaging are recyclable.

    Great lights, mind the size compatibility.

    The LUSA retrofit recessed lights are very easy to install. However, I did not pay attention that some of my existing cans were 6-inch lights instead of 4-inch resulting in me ordering extra lights I could not use. Customer service was excellent, helping me return them hassle-free. Just be aware that these lights are made for 4-inch cans. Other than that, they look amazing once installed.
