Brief Description
The H2Show LED light is a decoration item for aquariums or terrariums, produced by Hydor, a company with 31 years experience in the field. The product is available in 5 color versions – blue, green, red, white and multicolor.

The decoration uses LED technology to provide a beautiful lighting effect for fish tanks or artificial habitats sheltering small wild animals.

The 2 Watts LED included produces a focused light beam with a spotlight effect, useful in highlighting other decorative or landscape elements in the tank or terrarium.

Arguably a matter of taste, the most spectacular of the 5 versions is the multi-color one, which changes colors at intervals 9 seconds.

If used for an aquarium, the light can be placed on the tank wall, both below or above water level, using the suction cup provided as part of the product.

The device is powered by an 110 volts, wall plug-able, AC transformer, with an output of 5 volts. LED technology is energy efficient, so the product will not add much to your electricity bill. The LED

Before installation, check that all components of the light are intact. Pay special attention to the electrical cord that will power the LED light – part of it will be submerged in the water, so it is essential that the isolation is perfect. Also, allow for a dripping loop.

Use the suction cup to place the light on one of the walls of the tank or on the bottom. Then manually adjust the light to focus the spotlight on the decorative element you wish to highlight.

An additional suction cup is provided to help keeping the electrical cord in a fixed position on the tank’s wall.

Any maintenance activity should take place after disconnecting the light from the electrical plug.
Although the light does not require special maintenance, it is recommended to check periodically for algae or other deposits that might cover the light and eliminate them by using a soft piece of cloth. Keep in mind NOT to use solvents or detergents of any kind, as particles may remain attached to the light during cleaning and get dissolved into tank water.
