The Twinstar S IV (SA) LED Light is Twinstar’s fourth release of this series. It is a versatile fixture that provides hobbyists with two methods for mounting and illuminating planted tanks. It can be installed like a classic fixture, directly resting on the tank rim, or used with the Twinstar Wire Kit for a pendant-style LED light. This secondary method allows the unit to be used for a wider range of aquarium setups.
If you’re an aquarium enthusiast who is looking for vibrant colors or are growing aquatic plants that have strong light requirements, LEDS from the S Series are Twinstar’s most powerful options available. Each light produces ideal wavelength ranges (380-780nm), to ensure proper growth. Known for their quality, amplified colors are to be expected when using a Twinstar light.
