Light your reef the way nature intended with the Zoo Med Coral Sun Actinic 420 T8 Lamp in blue, sized at 48 inches.

A reef tank is a living system, and the right light is one of the most important things you provide for it. The 48-inch Coral Sun Actinic 420 T8 focuses on that deep blue end of the spectrum, the wavelength that, as Zoo Med explains, supports the photosynthetic life your corals and invertebrates depend on. Its European construction is built for quality color and a longer burn life, while the efficient T-8 format helps trim your electricity use compared with bulkier lamps. Pair it with your existing fixture, and enjoy a tank that looks like a slice of the ocean while supporting the animals living in it. For a serious reef keeper, this is dependable lighting done right. Give your corals the blue light they crave.
