You have heard this a hundred, probably a thousand times already. But we are still going to say it: proper lighting fixtures are absolutely crucial for a tank, whether it is freshwater or saltwater.

And you can’t simply go to the shop (physical or online) and pick a light that has the highest user reviews. Why? Because your lighting fixture needs to adhere to the needs of your fishes and plants, ergo your tank-inhabitants.

Different fishes and plants need different lights, some require bright, some dim.

So, in this article, we are going to present a product that has vibrant colors, and if you have a monotonous blue LED, this can be a perfect alternative.

Here, we have come up with the Kessil A360WE Tuna Sun review, which has individual spectrums that creates vivid colors for your planted tank. This is one of the best lights for aquarium plants. Besides, it gives a spotlight vibe but uses a wide-angle to spread the beam all over the tank.

·      High Performance and Design

In terms of efficiency and built quality, the Kessil A360WE Tuna Sun is unbeatable. It is compact and lightweight, which means it is easy to replace or carry.

Besides, even though it is small in size, the coverage is quite high. The maximum area is 24″ surface diameter; thus, you can estimate the range or make a guess of how long it can go.

·      Wide Angle

There are few things about this product that will surprise you indeed, and the wide-angle is one of them. You may think that it only illuminates a particular area, but this is not the case.

It comes with a beam that stretches out to 70 degrees vertically and 140 degrees horizontally, which covers all the edges. Thus, if you have a large shallow tank, this light can efficiently enlighten the entire area.

·      Double Peak

The dual peak technology is another great innovation of this product, which mainly focuses on photosynthetic absorption. It produces several wavelengths in an attempt to replicate the sun rays that eventually boost the photosynthesis cycle.

Moreover, this unit uses Kessil logic to customize the color contrast with light intensity. So, it keeps the consistency of color even in a broad-spectrum range.

·      One-handed Intensity Controller

Intensity management is always a bit confusing, especially when the controller is not user-friendly. But this product sets you free from any tedious complications.

It uses advanced ‘360 technology’ that deals with colors and intensity by two different knobs. Therefore, you can easily control the brightness as well as spectrums by few clicks.

The color range starts from 6000K, which is near to yellow and it goes to 9000K, which is pink. Besides, it offers white, which is in between these temperatures.

·      Energy Efficient Vivid Color

This unit has 90Watt LED lights that give a great effect of natural color inside your tank. It creates a healthy environment to make sure that your plants and fishes develop properly.

If you are using Halide lights in your aquarium, then we would like to let you know that this 90 Watt LED is much more efficient than that. It is an effective product that provides the maximum lighting to your tank-occupants.

Furthermore, the product is developed by keeping your electric bills in mind. Hence, more money saved. Besides, there is a hanging tab available in the box, so you don’t need to spend money on additional assembly tools.
