Product Overview
The E Series Vr. IV represents the sweet spot of the Twinstar lineup, offering a significant power boost over entry-level models while remaining more accessible than the flagship S Series. Engineered for versatility, this fixture provides the PAR intensity required for moderate to high-light demanding stem plants. With the included inline dimmer, it functions as a true all-arounder: easily dialed back for low-tech Anubias, Bucephalandra, and mosses, or cranked up to drive dense carpet growth.

Frequently Asked Questions
1. How does the Twinstar E Series Vr. IV compare to the B Line and S Series?
The E Series is Twinstar's mid-range power option. It outputs higher PAR and broader spectrum coverage than the budget B Line, making it suitable for moderate-to-high light plants. The flagship S Series remains the highest-PAR option for ultra-demanding Dutch-style stem tanks.
2. Can I adjust the legs on the E Series Vr. IV to fit slightly larger or smaller tanks?
No. The Version IV features fixed-width acrylic legs engineered to fit specific standard tank lengths flush. If you need adjustable legs that extend, select the Twinstar E Series Vr. V model.
3. Does this light include a dimmer?
Yes! The Twinstar E Series Vr. IV comes standard with an inline controller that allows you to easily adjust brightness levels to match your aquarium's specific CO2 and nutrient schedule.
