My High-End Lighting Choice: Kessil A360X Tuna Sun
For my 135-gallon planted aquarium, I wanted the best lighting possible. After researching extensively, I chose the Kessil A360X Tuna Sun, a high-end option known for its exceptional quality and vibrant light output. The price point is significantly higher than other options, but the promised light quality, features, and controllability made it an appealing investment for my project.

I'd previously used Kessil lights in my saltwater aquarium in California and was impressed by their performance. This time, I decided to try them again in my freshwater setup, wanting that same high-quality illumination.

Setting Up the System with Tank It Easy
The installation process involved collaboration with Tank It Easy, a reputable aquarium setup company in Chicago. They provided expert assistance, including advice on the lighting options and they helped in installing the lights under the aquarium hood.

Tank It Easy, known for both saltwater and freshwater setups, offered LED strip lighting as a more budget-friendly alternative. However, my previous positive experience with Kessil led me to choose them once again.

The 'Shimmer' Effect and Plant Growth
One of Kessil's signature features is the 'shimmer' effect – a rippling light pattern that mimics natural underwater light. In my heavily planted tank, however, the floating plants partially obscured this effect, along with reflections.

Despite the reduced shimmer, the lights provided excellent plant growth. My swords, hydrophilia, and floating plants thrived under their illumination.

Malfunctioning Lamp and Warranty Service
After six months, one of the Kessil lights malfunctioned. Initially, I anticipated a complicated warranty process, but I was pleasantly surprised.

The Kessil website provided clear troubleshooting steps. I followed them and determined that the power pack was likely the issue. This simple process showed the excellent resources Kessil provides.

Exceptional Customer Service
Contacting Kessil was incredibly easy. A live person, Morgan, answered the phone and provided outstanding support. She understood my problem, guided me through simple steps for a replacement, and even helped with timing for a Mother's Day family gathering.

The entire replacement process was smooth and efficient. They didn't require excessive paperwork or proof of purchase. I received a replacement power cord quickly and efficiently.

Conclusion: Kessil A360X Tuna Sun - Worth the Investment?
The Kessil A360X Tuna Sun lights are a premium investment, but their performance and customer service justify the cost. While other high-end brands exist, Kessil's responsive customer support sets them apart. The shimmer effect, although slightly reduced in my setup, enhances the aesthetic appeal.

Ultimately, the quality of light and exceptional warranty service make Kessil a strong contender in the high-end aquarium lighting market. Their responsiveness is a huge plus, especially considering the significant investment required for these lights.
