Fluorescent lighting is an efficient, effective choice for many aquariums. It evenly illuminates the full length of the aquarium and efficiently converts energy consumed into light. The complete line of Hagen Glo Fluorescent Bulbs provides fresh water and marine aquariums with lighting which will stimulate photosynthesis, while contributing to a beautiful aquarium display.


Incandescent lighting is available but does not offer the same aesthetic or efficiency value of fluorescent lighting.

When deciding on how much light to provide, a range of 1 to 3 watts per gallon will provide most fresh water aquariums with values that will provide optimal plant growth and visual presentation. Marine reef aquariums will sometimes require greater quantities of light to support the growth of certain coral species. When using the watts per gallon rule, a deduction of 10 to 15% of volume should be included to account for water displacement due to aquarium contents.

Light-Glo canopies are available in single and double bulb configurations. Both systems are equipped with high efficiency reflectors that maximize light emission. Revolutionary features of this lighting system include an anti-capillary barrier that prevents water seepage, and a sleek, modern look.
