The Lutron Hi-lume 1% EcoSystem/3-Wire Driver represents one of the most versatile LED drivers available in the lighting industry today. It delivers smooth, continuous dimming performance down to 1%, ensuring precise light control for virtually any LED fixture configuration, including both constant-current and constant-voltage applications. Its compatibility with a wide range of LED arrays, control protocols, and form factors makes it suitable for new installations as well as retrofit projects. The driver combines reliable performance, multiple control options, and robust protection features to support modern lighting systems that require flexibility, consistency, and longevity.
This LED driver provides continuous, flicker-free dimming from 100% to 1%, ensuring comfortable and seamless light transitions. It integrates easily with a variety of Lutron lighting control systems, including Energi Savr Node units with EcoSystem, GRAFIK Eye QS control units, PowPak dimming modules, and Quantum systems. Such integration enables it to function as part of a comprehensive EcoSystem solution, whether in new construction or upgrades to existing networks. It also supports standard 3-wire, line-voltage phase-control technology, allowing compatibility with all Lutron 3-wire fluorescent controls. Certain models are QwikFig compatible for quick configuration, and the driver includes built-in line-voltage miswire protection on EcoSystem control inputs. Each unit is 100% performance-tested at the factory to ensure reliability, and it carries a rated lifetime of 50,000 hours—at 65 °C (149 °F) for 40-watt models and 70 °C (158 °F) for 50-watt versions.
The Hi-lume 1% EcoSystem/3-Wire Driver family includes models with maximum power capacities of either 40 watts or 50 watts. The 40-watt and below range includes models within output ranges A–M and X–Z, while the 50-watt models correspond to output ranges N and W, available in the K-case form factor. These drivers are UL recognized and listed for the United States and Canada, NOM certified for use in Mexico, and Type TL rated. They comply with FCC Part 15 Class A requirements, and both Pulse Width Modulation (PWM) and Constant-Current Reduction (CCR) dimming methods are supported.
In terms of regulatory compliance, the driver meets ANSI C62.41 Category A surge protection standards up to 4 kV and conforms to FCC Part 15 Class A and CAN ICES-005(A) for electromagnetic compatibility. Lutron’s manufacturing facilities follow ESD reduction practices that align with ANSI/ESD S20.20 standards, and the company’s quality management systems are ISO 9001:2008 certified. UL 8750 recognition confirms the driver’s compliance with key LED safety and performance standards, and UL-recognized models are classified to UL 1598C for field-replacement capability. UL-listed form factors and Class 2 output options are available. Specific models, including L3DA4U1UKL-AV120 and L3DA4U1UKL-CV240, hold NOM certification for use within Mexico.
The UL 8750-listed versions of the Hi-lume driver include cULus certification for the United States and Canada. These models are pre-wired and ready for installation, with integral junction boxes that simplify wiring and reduce on-site setup time. The construction is fully compliant with UL 8750 standards and allows maximum driver-to-LED light engine wire lengths as specified in the Driver Leads documentation. The design emphasizes installation convenience while maintaining full compliance with electrical safety codes.
Environmentally, the driver operates quietly with an inaudible sound rating below 27 dB in ambient conditions. It functions within relative humidity up to 90% non-condensing and performs reliably in ambient temperatures as low as 0 °C (32 °F). These characteristics ensure dependable operation across a wide range of indoor conditions, making it suitable for both commercial and residential applications.
Performance specifications reinforce the driver’s professional-grade reliability. It supports dimming from 100% to 1%, operates across 120–277 V AC at 50/60 Hz, and achieves a lifetime rating of 50,000 hours under specified thermal conditions. The driver maintains a power factor above 0.90 and total harmonic distortion (THD) below 20% for loads greater than 25 watts, ensuring stable, efficient power delivery. Standby power consumption remains below 1 watt, and inrush current is limited to less than 2 amps through built-in circuitry that prevents circuit breaker tripping, switch arcing, or relay wear. The unit offers open- and short-circuit protection, patented thermal foldback protection, and non-volatile memory that restores driver settings after power interruptions. LEDs controlled by this driver can turn on directly to any dimmed level without flashing to full brightness, ensuring smooth user experience. The PWM dimming frequency is set at 550 Hz to prevent visible flicker.
For wiring and mounting, the driver is grounded through a mounting screw connected to the fixture or via terminal connection in the K-case. Terminal blocks accept a single solid wire per terminal in sizes ranging from 18 AWG to 16 AWG (0.75–1.5 mm²). All installations must comply with local and national electrical codes to ensure safety and grounding integrity.
Overall, the Hi-lume 1% EcoSystem/3-Wire Driver represents a reliable, flexible, and precision-controlled solution for LED lighting systems requiring smooth dimming, system compatibility, and long-term performance across a variety of commercial and residential applications.
