Zoo Med Coral Sun Actinic 420 T8 Lamp, Blue, 18 in

If you are tending a marine aquarium or a reef tank, the Zoo Med Coral Sun Actinic 420 T8 Lamp brings the deep blue light your living display craves. This is a high intensity actinic lamp with strong emissions in the short wavelength region of the spectrum, peaking at 420nm, so it reaches into the blue end of the light your tank wants. At 18 inches, it is sized for compact T8 fixtures, and it is the clean, modern way to light a coral system.

• High intensity actinic output peaks at 420nm, concentrating energy in the short wavelength region of the spectrum where reef life thrives.
• Zoo Med says it promotes the growth of zooxanthellae algae, which the brand notes are essential to the growth and well being of photosynthetic corals and invertebrates.
• Simulates the short wavelength blue light that penetrates to reef depth in nature, so your tank feels closer to the real thing.
• Output closely matches the absorption peak of chlorophyll used in photosynthesis, putting the light where your corals can use it.
• Ideal for all marine aquariums and reef tanks, a focused choice for serious coral keepers.
• Slim 18 inch T8 form factor fits standard compact T8 fixtures with ease.
• Energy saving T8 design draws less power than a thicker T12 size lamp, a friendlier load on your electric bill.
• Effective up to 10,000 hours, so it keeps working through long stretches of tank life.
• Made in Europe for ultra high quality, color, and longer burn life, part of Zoo Med's fluorescent aquarium lamp line.
• Pairs naturally with daylight lamps when you want a full, balanced spectrum over the tank.

Lighting is the heartbeat of a reef, and the right blue makes everything come alive. Give your corals and invertebrates the short wavelength actinic glow they were built for, and let your tank look its richest. The Coral Sun Actinic 420 T8 in 18 inches is a thoughtful, quality made piece of the puzzle for your underwater world.
