Zoo Med Coral Sun Actinic 420 T8 Lamp, Blue, 24 in

Bring true reef-depth blue light to your saltwater setup with the Zoo Med Coral Sun Actinic 420 T8 Lamp in blue, sized at 24 inches. This high intensity actinic lamp produces strong emissions in the short wavelength region of the spectrum, peaking at 420nm, the deep blue light that reaches reef depths in nature. For smaller marine tanks that still deserve serious lighting, the 24-inch length is an ideal fit.

• High intensity actinic output peaks at 420nm, simulating the short wavelength blue light that penetrates to reef depth in nature.
• According to Zoo Med, it promotes growth of zooxanthellae algae, which the brand notes is essential for the growth and well being of all photosynthetic corals and invertebrates.
• Output closely matches the absorption peak of chlorophyll used in photosynthesis.
• Ideal for all marine aquariums or reef tanks, suiting a range of saltwater displays.
• Part of Zoo Med's line of fluorescent aquarium lamps made in Europe for ultra high quality, color, and longer burn life.
• Energy-saving T-8 size that Zoo Med says can save you up to $30.00 per year in electricity over thicker T-12 lamps.
• Effective up to 10,000 hours for steady, long-running use.
• The 24-inch length is well matched to smaller fixtures and compact reef tanks.
• Casts a deep blue tone that highlights the color and depth of corals and invertebrates.
• Made by Zoo Med, a name marine and reptile keepers know and trust.

Even a smaller reef tank is a complete little ecosystem, and the light you give it shapes how its inhabitants thrive. The 24-inch Coral Sun Actinic 420 T8 concentrates on that deep blue wavelength, the light that, as Zoo Med explains, supports the photosynthetic corals and invertebrates living in your care. Its European build is made for quality color and a longer burn life, while the efficient T-8 format helps keep your electricity use down compared with thicker lamps. Slot it into your existing fixture and watch your compact reef take on that mesmerizing oceanic glow. For the marine hobbyist running a smaller display, this is reliable, reef-focused lighting that earns its place. Give your corals the blue light they reach for in the wild.
