Zoo Med Reef Sun 50/50 Actinic Daylight T8 Lamp, White, 18 in

Light up your smaller aquarium with the Zoo Med Reef Sun 50/50 T8 Lamp in the 18 in white size. This compact bulb pairs 6500K trichromatic daylight phosphor with actinic 420 phosphor in the same lamp, giving you high intensity full spectrum illumination that is strong in the short-wavelength blue region. According to Zoo Med, that blue region is essential for photosynthetic corals and invertebrates, while the 6500K daylight balance brings natural color enhancement and viewing pleasure to your tank. It is a tidy, single-bulb way to give a shorter fixture both daylight and actinic tones at once.

• 50/50 combination of 6500K daylight phosphor and actinic 420 phosphor in one lamp, so both tones come from a single bulb.
• High intensity full spectrum illumination that is strong in the short-wavelength blue region.
• Zoo Med notes the blue region is essential for photosynthetic corals and invertebrates.
• Balanced with 6500K daylight for natural color enhancement and easy, pleasant viewing.
• Ideal for all marine aquariums, reef aquariums, African cichlids, and discus fish alike.
• Energy-saving T8 size, which Zoo Med says can save up to $30.00 per year in electricity over thicker T12 lamps.
• Made in Europe, which Zoo Med highlights for high quality, color, and longer burn life.
• Effective up to 10,000 hours, per Zoo Med, for long stretches between replacements.
• The shorter 18 in length suits compact tanks and smaller T8 fixtures.
• One bulb covers both daylight and actinic lighting needs in a tidy, space-saving size.

For a smaller reef, marine, cichlid, or discus tank that takes an 18 in bulb, the Zoo Med Reef Sun 50/50 T8 Lamp is an easy way to combine daylight and actinic tones together in a single energy-saving lamp. Zoo Med builds its full line of fluorescent aquarium lamps in Europe and rates this one effective up to 10,000 hours of service, so it holds its own in a compact fixture for the long haul. Fit it into a compatible T8 fixture sized for this shorter length, give your corals and invertebrates the short-wavelength blue they rely on, and enjoy watching your fish glow under balanced full spectrum light every single day.
