Performance & Additional Information

The Sylvania Quicktronic Helios dimmable ballast supports PENTRON HO, PENTRON HO Circline, and DULUX® L T5 lamps, offering flexibility across a full dimming range. It integrates seamlessly with daylight harvesting systems, occupancy sensors, and building automation, helping reduce energy costs while maintaining high-quality light output.

With performance up to 188% higher lumen output compared to T8 ballasts, this ballast allows lighting designers to replace multi-lamp T8 systems with fewer T5HO lamps, cutting both energy use and maintenance costs. Available in one- and two-lamp models for 120V and 277V systems, it is a versatile solution for modern lighting projects.
