120–277Vac LED Drivers for Commercial Lighting
All current R2 models use a 120–277Vac rated-input platform. This covers common commercial lighting supplies including nominal 120V, 208V, 240V and 277V.
The wide-input architecture allows compatible luminaire families to operate across several North American commercial electrical systems without changing the basic R2 driver platform.
AC input voltage is different from LED output voltage. A fixture supplied from 277Vac can use an R2 driver that provides regulated 180–260Vdc constant-current output to the LED string.
180–260V Constant-Current LED Drivers
The complete R2 range uses a 180–260Vdc high-voltage constant-current output architecture. This makes the series suitable for LED boards designed around relatively long series-connected LED strings.
A higher LED-string voltage allows substantial fixture power to be delivered at lower current than a low-voltage high-current architecture. Depending on the fixture design, this can influence PCB routing, conductor size, connector requirements and internal power density.
The LED module's minimum and maximum forward voltage must remain inside the 180–260Vdc operating window of the selected R2 driver.
Non-Isolated LED Driver Architecture
R2 uses a non-isolated power architecture. This allows a compact and efficient driver design, but the LED output does not provide galvanic isolation from the mains input in the same way as an isolated driver topology.
For this reason, fixture designers must evaluate PCB insulation, creepage and clearance, wiring, connectors, accessible conductive parts, enclosure construction and applicable safety requirements as part of the complete luminaire design.
Driver-level certification does not automatically certify the finished luminaire.
Compact LED Driver for Shoebox Lights
R2 is especially relevant to shoebox luminaires where the LED driver must fit into a restricted driver compartment while supplying a relatively high-voltage LED string.
The current 40W and 60W models, for example, use an approximately 130 × 48 × 32mm enclosure. This compact format helps fixture manufacturers integrate the driver into smaller shoebox, wall and canopy-style housings.
Mechanical dimensions increase with power, so the drawing for the exact R2 model should always be reviewed before luminaire tooling or mounting-point design.
R2 LED Drivers for Wall Lights and Wall Packs
Wall-mounted outdoor luminaires often require compact power electronics because the available enclosure depth and width are limited.
R2 provides 40W through 320W power classes within the same 180–260Vdc electrical architecture, allowing compatible wall-light and wall-pack designs to scale across several output levels while maintaining a common driver family.
R2 Drivers for Linear High-Bay Lighting
The R2 platform is also positioned for compatible linear high-bay and industrial luminaires using high-voltage LED strings.
Its compact non-isolated architecture can be useful where the driver is integrated into the luminaire frame or a protected internal compartment and where a 180–260Vdc LED load matches the selected current range.
R2 Drivers for Street and Area Lighting
R2 can support compatible street and area luminaires when the fixture uses a 120–277Vac supply, a 180–260Vdc LED string and a driver power class between 40W and 320W.
Because R2 uses an IP42 enclosure, the complete street-light housing must provide the required outdoor environmental protection around the driver and electrical connections.

320W R2 High-Power Outdoor LED Driver
R2-320X-260 is the highest-power model in the current R2 outdoor range. It provides approximately 1.20–1.60A within the 180–260Vdc output window and reaches approximately 96% typical efficiency.
The 320W model provides a compact high-voltage driver direction for compatible high-output outdoor and industrial luminaires where a non-isolated architecture is appropriate.
Programmable R2 Outdoor LED Drivers
R2 supports offline programming, allowing compatible output parameters to be configured within the electrical limits of the selected model.
For OEM luminaire manufacturers, programmable current can allow one R2 power platform to support related fixture variants with different operating points, provided that LED voltage, current, maximum power and thermal limits are respected.
The programmed setting should be defined before production so the driver configuration, fixture wattage and luminaire label remain consistent.
R2 Control and Dimming Configurations
Although this R2 series is located under the fixed-output / non-dimmable outdoor category, the underlying R2 platform supports multiple control configurations depending on model code and project requirements.
| Control Direction | Available Platform Function |
|---|---|
| Non-Dimmable | Fixed-output / ON-OFF project configuration |
| 0–10V | Analog external dimming on compatible configurations |
| PWM | PWM control for compatible lighting controllers |
| Rx / Resistor | Additional external-control directions depending on configuration |
| Timer Dimming | Scheduled output profiles for compatible outdoor-lighting projects |
| DALI | Digital-control configuration within the wider R2 platform |
Control availability should be confirmed for the exact model code when requesting samples or production units.
Photosensor-Compatible Outdoor LED Driver Platform
Current R2 documentation identifies the platform as photosensor compatible. This can be relevant to outdoor fixtures that need to respond to ambient light levels or operate as part of a photocell-controlled lighting system.
The exact sensor interface and required driver configuration should be confirmed during project development.
Fixed-Output R2 LED Drivers
For projects that do not require external dimming, R2 can be specified in a non-dimmable / fixed-output configuration.
This provides a straightforward operating direction for shoebox lights, wall packs, area lights and industrial fixtures that primarily use branch-circuit ON/OFF control.
Because R2 is a configurable platform, the fixed-output requirement should be explicitly stated when requesting samples or production quotations.
IP42 LED Driver for Protected Luminaire Integration
Current R2 models use an IP42 enclosure. This means R2 should not be positioned as a standalone waterproof LED driver.
Instead, the driver is intended to be integrated inside a luminaire or enclosure that provides the environmental protection required by the final installation.
This distinction is important for street, wall and shoebox lighting because the IP rating of the finished fixture depends on the complete housing, seals, connectors, cable entries and installation design rather than the driver alone.
Need a Waterproof Alternative? Compare R3
Projects that use the same broad 120–277Vac and 180–260Vdc electrical direction but require stronger driver-level protection should compare the R3 waterproof outdoor platform.
R3 provides corresponding 40W through 320W power classes with IP65 / IP67 enclosure configurations for outdoor applications requiring greater resistance to dust and moisture.

Efficiency and Power Factor
Current R2 models provide typical efficiency from approximately 94% to 96%, with the 320W model reaching approximately 96%. Power factor is specified above 0.95 across the current series.
Actual efficiency depends on input voltage, programmed output current, LED operating voltage and thermal conditions. Model-level performance should therefore be evaluated at the intended fixture operating point.
DM 6kV / CM 6kV Surge Protection
Current R2 technical data specifies differential-mode and common-mode surge protection up to 6kV.
Surge protection is relevant to outdoor and industrial lighting because long cable runs, switching events and lightning-related disturbances can expose luminaires to electrical transients.
Driver-level surge capability should be coordinated with facility grounding and any system-level surge-protection strategy.
SCP, OVP and OTP Protection
Current R2 products include short-circuit protection, over-voltage protection and over-temperature protection.
These functions provide driver-level protection during abnormal conditions but do not replace correct LED-board design, fixture thermal management, branch-circuit protection or grounding.
cULus, CE and Class P LED Driver Platform
Current R2 product documentation lists cULus, CE and Class P certifications for the platform.
Certification should be confirmed for the exact ordered model and target market. Driver-level certification does not automatically certify the complete outdoor or industrial luminaire.
