Description
One-Lux Unity-LED™ — Combi LED Mains Emergency Drivers
The One-Lux Unity-LED™ range consists of maintained combi LED mains / emergency drivers
in a compact, low-profile enclosure. Designed for either internal or remote self-contained applications,
Unity-LED uses SELV-isolated constant-power technology to run almost any LED lamp or array rated
from 20–55 V in both mains and emergency mode — simplifying the creation of emergency versions
of existing LED luminaires without separate emergency LEDs, drivers or connectors.

Key Features
- ✅ Maintained emergency lighting modules combining both mains and emergency drivers in one unit.
- ✅ Compact, low-profile enclosure suitable for fitting inside luminaires or remote enclosures.
- ✅ SELV isolated LED driver technology will run any LED lamp or array rated from 20–55 V
in both mains and emergency modes. - ✅ High-efficiency mains driver for LED lamps up to around 30Â W
(higher output versions available on request). - ✅ Available with 2- or 3-cell NiCd / NiMH batteries and a 3.2Â V LiFePOâ‚„ option
for extended life and reduced maintenance. - ✅ 1-hour or 3-hour autonomy options (NiCd / NiMH versions).
- ✅ User-selectable mains-mode output current with additional 10Â %, 20Â % & 25Â % reductions
on Unity-LED PHASE versions. - ✅ Optional 1–10 V dimming and occupancy detector input for energy-saving control in mains operation
- ✅ Protected against short-circuit and open-circuit lamp conditions for robust, reliable operation.
- ✅ Designed and manufactured in Great Britain for assured quality and technical support.

Applications
- ✅ LED panels, downlights and linear luminaires requiring combined mains and emergency control gear.
- ✅ OEM luminaire manufacturing where a single combi driver simplifies wiring and reduces part count.
- ✅ Internal or remote self-contained emergency solutions, including use within Unity-LED Remote™
and other remote box assemblies. - ✅ Retrofit conversions of existing LED fittings to maintained emergency operation without redesigning
the light engine.
Why Choose Unity-LED™?
- ✅ Provides a single, constant-power solution for both mains and emergency modes, simplifying
luminaire design. - ✅ User-selectable output current and step reductions provide flexibility across multiple luminaires
from one driver platform. - ✅ Options for NiCd, NiMH and LiFePOâ‚„ batteries and 1- or 3-hour autonomy cover a wide range
of project specifications. - ✅ Optional dimming and sensor inputs support energy-efficient, controlled lighting schemes.
