Reduces the need for use of actinic fluorescent tubes!

This 20K Halide bulb is the best choice for promoting coral and plant growth and for creating a natural ripple-effect in your aquarium; because Halides imitate the ripple-effect provided by sunlight as closely as possible, they are just what your aquarium needs to ensure that conditions remain healthy and reach optimum performance. So what makes Halides bulbs so special? Halides emit their light from a single focus point…just like the sun and this means that the light is “rippled” in the most natural way and plants and coral reap the benefits.

This 20K Halide bulb will bring about a higher concentration of blue in the spectrum; your corals will appear more vibrant…greens and blues will stand out and your aquarium will benefit from the sustained and close-to-natural light source. The mood brought about by the 20K Halide will be that of a deeper setting or an evening tone creating an ambient and relaxed mood.  Why Halides ?

Why choose a 20K Halide bulb and what else do I need to know?

The 20K Halide bulb will reduce the need for additional actinic fluorescent tubes for balance and will also help to create a stable and healthy environment for your aquarium. Halide bulbs offer the ultimate in quality and performance at a low price. A 250W Halide bulb will give you the “ripple” effect and can reach right down to the deepest section of your tank and benefit all of the plants and corals within.
