Sera Blue Sky Royal[Power - 15W]

12,000 Kelvin - Intense bright blue light - simulates lighting conditions in tropical rivers and lakes.

Thanks to its perfectly balanced spectrum, sera Blue sky can be used as a single tube or in conjunction with sera Deep sea, as a light source for marine aquariums.

The combination with SERA Tropic Sun is optimal for freshwater aquariums.

Good lighting for aquariums is not only important for fish — it is also essential for any live plants growing in your tank. Plants need light for photosynthesis to manufacture food from carbon dioxide and water. Tropical plants, for example, need 12 hours of light daily, while cold-water plants need light changes according to the seasons.

Important: The lifespan of aquarium lamps is 12 Months. The lamp's spectrum gradually changes and after this period, it cannot function as an aquarium lamp for the intended purpose.

For best results, replace aquarium lamps every 12 Months.

Essentially, watts tell you how much energy the light consumes, lumens tell you how bright the light is, and Kelvin tells you the color of the light.
