R3 120–277V Waterproof Outdoor LED Drivers
FAHOLD R3 is a waterproof non-isolated constant-current LED driver platform developed for professional outdoor luminaires using high-voltage LED strings. The current range includes eight power classes from 40W to 320W, all operating from 120–277Vac input and providing a common 180–260Vdc LED output architecture.
R3 is designed for shoebox lights, wall lights, street lights, area lighting and other outdoor fixtures where compact driver dimensions and IP65 / IP67 environmental protection are required.
Unlike an internal-use driver that relies primarily on the luminaire enclosure for protection, R3 provides waterproof driver-level protection as part of the power-supply platform. Final fixture IP performance still depends on cables, connectors, seals, housing and installation conditions.

The listed current values are maximum current capabilities for each power class. The selected LED operating point must remain within the driver’s output-voltage, current, maximum-power and thermal limits; maximum voltage and maximum current should not be assumed to occur simultaneously.
40W to 320W Waterproof LED Driver Range
R3 provides eight power classes for outdoor luminaires ranging from compact wall and shoebox fixtures to higher-output roadway and area lighting.
| Power Direction | Typical Application Direction |
|---|---|
| 40W–80W | Compact wall lights, smaller shoebox lights and lower-output outdoor fixtures |
| 100W–150W | Wall packs, shoebox luminaires, street lights and commercial area lighting |
| 200W–240W | Higher-output roadway, shoebox and area luminaires |
| 320W | High-output street, area and professional outdoor lighting |
Rated wattage should not be used as the only selection criterion. The LED module's forward-voltage range and required operating current must also match the selected R3 driver.
120–277Vac Waterproof LED Drivers
All current R3 products use a 120–277Vac rated-input platform. This covers common commercial lighting supplies including nominal 120V, 208V, 240V and 277V.
This wide-input range can simplify development of outdoor luminaires intended for multiple North American commercial electrical environments.
AC input voltage is independent from LED output voltage. A fixture connected to 277Vac mains can use an R3 driver that supplies regulated 180–260Vdc constant-current power to the LED string.
180–260Vdc High-Voltage LED Driver Platform
Every current R3 model uses a 180–260Vdc high-voltage LED output window. This architecture is designed for luminaires that use relatively long series-connected LED strings.
For a given power level, a higher LED-string voltage can reduce required DC current compared with a low-voltage high-current architecture. This can influence LED-board layout, cable size, connectors and fixture integration.
The complete LED forward-voltage range, including temperature and production tolerance, should remain within the supported 180–260Vdc operating window.
Non-Isolated Waterproof LED Driver Architecture
R3 uses a non-isolated power topology. This allows a compact and efficient high-voltage driver architecture, but the LED output does not provide galvanic isolation from mains in the same way as an isolated topology.
Fixture designers should therefore evaluate insulation, creepage and clearance, PCB construction, connectors, wiring, accessible components and enclosure requirements as part of the complete luminaire safety design.
The waterproof driver enclosure does not eliminate the need for correct high-voltage LED-side safety engineering.
IP65 and IP67 Waterproof Outdoor LED Drivers
R3 is differentiated from the R2 platform primarily by its outdoor enclosure protection. Current R3 products provide IP65 / IP67 enclosure configurations for luminaires that require stronger driver-level protection against dust and moisture.
IP65 and IP67 refer to the driver enclosure or ordered configuration. They do not automatically determine the environmental rating of the entire luminaire.
Cable entries, connectors, gaskets, luminaire housing, mounting orientation and installation conditions must also meet the required outdoor protection level.
Waterproof LED Drivers for Shoebox Lights
Shoebox luminaires are a strong application fit for the R3 platform because they often combine high-voltage LED strings with restricted driver compartments and demanding outdoor exposure.
R3 provides 40W through 320W power classes within the same 180–260Vdc electrical architecture, allowing manufacturers to use one broader waterproof driver family across several shoebox-light sizes.
For final matching, confirm LED voltage, current, maximum power, driver dimensions and required control configuration.
Waterproof LED Drivers for Wall Lights and Wall Packs
Wall-mounted outdoor fixtures are directly exposed to humidity, rain, dust and temperature variation, making enclosure protection an important driver-selection parameter.
The compact R3 aluminum housing and IP65 / IP67 configuration provide a suitable direction for compatible wall lights and wall packs using 180–260Vdc LED strings.
Lower power classes such as 40W, 60W, 80W and 100W are particularly relevant to compact wall-mounted luminaires.
R3 Waterproof Street Light LED Drivers
R3 can support compatible street and roadway luminaires from 40W to 320W when the LED module uses a 180–260Vdc high-voltage architecture.
Its waterproof enclosure reduces dependence on the outer luminaire as the only environmental barrier around the driver, while configurable control options support different roadway-lighting requirements.

The current enclosure measures approximately 214 × 54 × 32mm, maintaining the same narrow 54mm-class width while extending the platform to 320W.
Compact 54mm-Class Waterproof Driver Platform
A useful mechanical characteristic of the R3 family is its narrow enclosure format. Current models use an approximately 54mm-wide and 32mm-high housing, while enclosure length increases with power.
Lower-power 40W through 100W models use approximately 139mm length, while higher-power products extend to approximately 159mm at 150W, 178mm at 200W, 198mm at 240W and 214mm at 320W.
This narrow format is useful for shoebox, wall and compact roadway fixtures where driver-compartment width is limited.
R3 Control Configurations
R3 is a configurable outdoor-driver platform rather than a permanently non-dimmable product family. The “X” position in the model code identifies the control configuration.
| Configuration | Control Direction |
|---|---|
| Type B | 0–10V / PWM / Rx control |
| Type D | Light control / power adjustment with optional 0–10V control |
| Type E | 0–10V dimming / optical control / DIP-switch power adjustment / optional external NTC |
| Type V | Non-dimmable with potentiometer fine output-current adjustment |
The exact R3 configuration should be specified when requesting samples or production units rather than assuming all X-code versions use the same control functions.
0–10V Waterproof Outdoor LED Drivers
Compatible R3 Type B and Type E configurations support 0–10V control for outdoor luminaires requiring externally adjustable light output.
0–10V control can be useful in street, area and commercial outdoor-lighting systems where a compatible controller or sensor adjusts fixture output according to schedule or operating conditions.
Controller compatibility, wiring and low-end dimming behavior should be validated with the selected R3 configuration.
PWM and Rx Control Options
R3 Type B configurations support 0–10V, PWM and Rx control. This provides additional interface options for compatible fixture controllers and lighting-management systems.
The required signal interface should be defined during project development so the correct control code is selected before production.
Optical Control for Outdoor Lighting
R3 Type D and Type E configurations provide optical-control directions for outdoor luminaires that need to respond to ambient lighting conditions or compatible photosensor systems.
Optical-control requirements should be confirmed together with the sensor architecture, fixture wiring and required output behavior.
DIP-Switch Power Adjustment
Compatible Type E R3 configurations provide DIP-switch power adjustment. This allows supported fixture power settings to be selected through the configured driver interface.
For OEM manufacturers, adjustable power can help one driver direction support several related fixture-output targets when all voltage, current, power and thermal limits are respected.
Optional External NTC Support
R3 Type E configurations can provide optional external NTC support. An external temperature-sensing interface can be useful in luminaire designs where driver output needs to interact with fixture thermal-management requirements.
The exact NTC implementation and response behavior should be confirmed during project engineering rather than assumed from the generic series description.
Non-Dimmable R3 Configuration
For outdoor fixtures that do not require external dimming, R3 Type V provides a non-dimmable configuration with potentiometer fine output-current adjustment.
This makes it possible to use the waterproof R3 platform in straightforward fixed-output projects while retaining fine current adjustment during fixture setup.
R3 vs R2 Outdoor LED Drivers
R2 and R3 share a similar 120–277Vac input, 180–260Vdc output and 40W–320W power direction, but their environmental-protection strategy is different.
| Requirement | R3 | R2 |
|---|---|---|
| Rated Input | 120–277Vac | 120–277Vac |
| Output Platform | 180–260Vdc | 180–260Vdc |
| Power Range | 40W–320W | 40W–320W |

High-Efficiency Waterproof LED Drivers
Current R3 products provide approximately 94% to 96% typical efficiency depending on power class. The 40W and 60W models are approximately 94%, 80W through 240W are typically around 95%, and the 320W platform reaches approximately 96%.
High efficiency reduces internal driver losses and thermal load, which is particularly useful in sealed outdoor luminaires where heat dissipation must be managed carefully.
Actual performance depends on AC input, LED operating point, control configuration and thermal conditions.
Power Factor Above 0.95
Current R3 products specify power factor above 0.95 across the series.
Power factor should be evaluated together with efficiency, LED compatibility, control requirements, enclosure protection and the complete electrical design of the outdoor luminaire.
SCP, OVP and OTP Protection
The current R3 platform includes short-circuit protection, over-voltage protection and over-temperature protection.
These protection functions help the driver respond to abnormal electrical or thermal conditions but do not replace correct LED-board design, fixture cooling, grounding, wiring or branch-circuit protection.
cULus and CE Waterproof LED Driver Platform
Current R3 product documentation lists cULus and CE certifications for the platform.
Certification should be confirmed for the exact ordered configuration and target market. Driver certification alone does not certify the complete street light, wall light, shoebox fixture or other finished luminaire.
How to Select the Right R3 Waterproof LED Driver
- Confirm the AC input.
Verify that the project supply falls within the 120–277Vac rated-input range. - Define the LED forward-voltage window.
Provide the minimum, nominal and maximum forward voltage of the LED string. - Confirm 180–260Vdc compatibility.
The complete LED operating-voltage range must remain within the R3 platform window. - Determine the required LED current.
Confirm that the selected R3 power class can provide the required operating current while remaining within rated power. - Select the required wattage.
Choose from 40W, 60W, 80W, 100W, 150W, 200W, 240W or 320W. - Define the control configuration.
Specify 0–10V / PWM / Rx, light control, optical control, DIP-switch adjustment or fixed-output operation as required. - Define environmental protection.
Confirm whether the project requires the IP65 or IP67 driver configuration and ensure the complete luminaire is designed accordingly. - Review mechanical dimensions.
Confirm enclosure length, 54mm-class width, mounting position and cable routing before final fixture tooling. - Review thermal and safety requirements.
Because R3 is a non-isolated high-voltage platform, evaluate insulation, LED accessibility, temperature and complete luminaire construction. - Confirm certification requirements.
Verify the exact driver configuration and finished-luminaire compliance requirements for the target market.
