Zoo Med T8 Coral Sun Actinic 420

Coral Sun® is a high-intensity actinic lamp with strong emissions in the short wavelength region of the spectrum, peaking at 420nm. It promotes the growth of zooxanthellae algae, essential for the growth and well-being of all photosynthetic corals and invertebrates. This bulb simulates the short wavelength blue light which penetrates to reef depth in nature. Output closely matches the absorption peak of chlorophyll used in photosynthesis. Ideal for all marine aquariums or reef tanks. Zoo Med’s line of fluorescent aquarium lamps is made in Europe for ultra high quality, color, and longer burn life. Our energy saving T8 sizes can save you up to $30.00 per year in electricity over the thicker T12 size lamps! Effective up to 10,000 hours.
