The blue wavelength of LED can allow algae on reef organisms such as anemones and lakes to fully carry out photosynthesis and provide more nutrition for organisms. At the depth of 50CM, it can reach up to 6,000 LUX, which is more than 15% brighter than 250W HQI lamp, equivalent to two 150 WHQI lamps. Turn on white light and blue light at the same time (blue light and white light only), which can realize illumination with different color temperatures and wavelengths, and provide a wider demand for photosynthesis of your aquatic plants.
