Unboxing and Initial Impressions
The Finnex Stingray 2.0 arrived, and my first impression was positive. The packaging was sturdy and well-designed, protecting the light during shipping.

Upon opening, the build quality felt solid and robust, exceeding my expectations. The light itself was sleek and modern, aesthetically pleasing for any aquarium setup.
I immediately compared it to my previous marine plus lights and the original Finnex light I already owned. The Stingray seemed promising.
Lighting Modes and Functionality
The Stingray 2.0 boasts a three-way switch. The first setting activates all blue LEDs, offering a stunning deep blue ambiance.

The middle position turns off all LEDs, providing a convenient off function. The third setting is remarkably bright, showcasing a mix of white, red, and blue LEDs.

I found the all-blue setting particularly effective for nighttime viewing, while the full-spectrum setting is ideal for daytime.
Brightness and Color Comparison
The full-spectrum setting, while bright, was initially overwhelming. It revealed too much detail of the rocks, and I found it less aesthetically pleasing than I anticipated.

In contrast, the all-blue mode was beautifully subtle, but lacked the vibrancy of my previous setup with the original Finnex light. The blue intensity differed significantly.

I experimented by adding the original Finnex light, creating a layered approach to achieve the desired blue tones and brightness.
PAR Meter Readings and Coral Growth
I utilized a PAR meter to objectively measure light intensity. With the Finnex Stingray 2.0 alone, the PAR readings were surprisingly high, potentially exceeding the ideal range for my corals.

By incorporating my other lights and adjusting settings, I achieved a more balanced PAR level, optimal for fostering coral growth. The original Finnex produced a better PAR reading at a lower intensity for my blue light needs

The balance between white and blue light was crucial; too much white resulted in a harsh, overexposed look that I wasn't happy with.
Final Verdict and Recommendations
The Finnex Stingray 2.0 offers impressive brightness and a visually appealing design. However, the intensity, especially in full-spectrum mode, might be too much for some setups.

For optimal results, experiment with lighting modes and potentially incorporate other lights, as I did with the original Finnex, to achieve the desired ambiance and PAR levels for your specific corals.
Ultimately, the Finnex Stingray 2.0's value depends on your individual tank and coral needs. It excels as a supplemental light source but might be too strong on its own for sensitive corals. I will be returning the additional Stingrays I purchased.
