Penn-Plax Cascade Ultra Bright Fully Submersible Aquarium Fish Light, Blue

• This LED light makes a charming accent, perfect for desktop and nano aquariums or other fish tanks where space is a bit tight.
• Waterproof, fully submersible design can be clipped onto your tank or attached to a wall via the provided suction cups.
• Powered by a USB cable that can be connected to a wall adapter, computer or even a gaming console (each sold separately).
• Safe for use in freshwater and saltwater tanks.
• The 68-inch cord and on-off switch accommodate a wide variety of setups.

For a strong and secure bond with the suction cups, please clean the desired location beforehand, and then rinse the suction cups with water. This ensures that the aquarium accent light will stay in place within the fish tank.
