Twinstar LED - E Series Vr. IV Aquarium Light Fixture

Twinstar LEDs combine sleek design with true full‑spectrum performance, earning a loyal following in the aquarium community. By delivering the ideal 380–780nm range, these lights reveal the real colors of your plants and fish without the muddy yellow tones common in basic fixtures. Your aquascape ends up looking sharp, vibrant, and beautifully clear.

The E Series Vr. IV is the happy medium of the Twinstar lineup, offering a significant power boost over the C Line while remaining more accessible than the flagship S Series. Engineered for versatility, this popular fixture provides the intensity required for moderate to high-light demanding plants. With the included dimmer, it becomes a true all-arounder, easily dialed back for low-tech Anubias, Bucephalandra, and Mosses, or cranked up for lush stem growth.
