||Accentuate coral fluorescence and provide light for coral growth
Specialty VHO (Very High Output) fluorescent lamp streamlines reef aquarium lighting. Space-saving UV Lighting Company 454 VHO Lamp does double duty by emitting both tri-band blue and actinic light. Unique 85% tri-band blue spectrum and 15% actinic spectrum blend boosts aquarium coral fluorescence and photosynthesis. 180 degree internal reflector allows 40% more light output for brilliant coral illumination. T-12 (1-1/2") diameter fluorescent lamps. Useful life of 4,500 hours.
Q. What does T-12 stand for?
The "T" number or the T-rating indicates the diameter of the fluorescent lamp. The T-rating of fluorescent lamps are described in increments of 1/8 of an inch. So a T-8 fluorescent lamp is 8/8, or one inch in diameter and a T-12 fluorescent lamp is 12/8 or 1-1/2 inches in diameter.
Q. What does NO, HO and VHO stand for?
A. There are many different types of fluorescent lighting systems and the different types are sometimes categorized and distinguished by their light output. NO stands for Normal Output, HO for High Output, and VHO for Very High Output. Each of these different fluorescent light systems requires ballasts and lamps specific to that system. The lamps of these different systems cannot be interchanged. VHO fluorescent lamps are similar in design to standard fluorescent lamps, but by using a special ballast, they produce three times more light than a standard fluorescent tube. Instead of using 4 to 6 standard fluorescent lamps, you need only 2 VHO tubes to generate the same amount of light for your aquarium.
