Best Aquarium Light 5000ik Buying Guide
Light Spectrum and Color Temperature
The best aquarium lights offer a full spectrum mimicking natural daylight. A color temperature between 6500K and 7500K supports plant growth while keeping fish colors vibrant. Many models also include dedicated blue and red wavelengths for photosynthesis.
