FAHOLD T1 compact outdoor LED drivers provide programmable constant-current power for space-constrained street lights, tunnel lights, display lighting and auxiliary outdoor luminaires. The current series includes four models from 26W to 60W, all using a 100–277Vac wide-input platform with IP65 / IP67 outdoor enclosure configurations.
Available LED output platforms include 27–54Vdc, 27–56Vdc and 54–85Vdc, with output-current capability from approximately 0.30A to 1.66A depending on model. Compatible configurations support 0–10V, PWM, resistor and timer dimming, offline output-current programming, potentiometer adjustment and DALI control.
Choose T1 when fixture size is a priority but professional outdoor protection and configurable control are still required. Compare the four models below by wattage, LED voltage, current range and control configuration.
T1 Compact Outdoor LED Drivers for Space-Constrained Fixtures
FAHOLD T1 is a compact constant-current outdoor LED driver platform developed for professional luminaires where driver installation space is limited. Typical applications include compact street lights, tunnel lights, display lighting, auxiliary outdoor fixtures and other commercial LED luminaires requiring a small power-supply footprint.
The current T1 series uses 100–277Vac input and includes four products from 26W to 60W. Available LED output windows include 27–54Vdc, 27–56Vdc and 54–85Vdc, allowing the series to support several lower-power LED-module architectures.
T1 extends the broader FAHOLD programmable outdoor-driver architecture into lower power classes while retaining configurable dimming, programming, outdoor protection and surge capability.
Compare T1 26W, 40W and 60W Outdoor LED Drivers
| Model Direction | Rated Input | Output Voltage | Output Current | Typical Efficiency |
|---|---|---|---|---|
| 26W | 100–277Vac | 27–54Vdc | 0.30–0.80A | 86.5% |
| 40W | 100–277Vac | 27–56Vdc | 0.74–1.11A | 88% |
| 60W Low-Current | 100–277Vac | 54–85Vdc | 0.30–1.10A | 88% |
| 60W High-Current | 100–277Vac | 27–56Vdc | 1.11–1.66A | 88% |
The two 60W models demonstrate why rated wattage alone cannot determine driver compatibility. One is designed for a higher-voltage, lower-current LED string, while the other is intended for a lower-voltage, higher-current LED module.
26W–60W Compact LED Driver Platform
T1 focuses on the lower-power end of professional outdoor lighting. Rather than competing directly with the 100W–400W F1 platforms, it is designed for luminaires where reduced power and smaller driver dimensions are more important.
The current series covers 26W, 40W and 60W fixture classes, making it suitable for compact outdoor products, auxiliary lighting and smaller commercial luminaires that still require professional control and protection functions.
100–277Vac Compact Outdoor LED Drivers
All current T1 products use 100–277Vac rated input. This broad input range covers common commercial lighting supplies including nominal 120V, 208V, 220–240V and 277V.
Wide AC input can help luminaire manufacturers develop one compact fixture platform for multiple commercial electrical environments.
AC input voltage is separate from LED output voltage. A fixture supplied from 277Vac may still use a T1 driver providing regulated 27–56Vdc or 54–85Vdc constant-current output to the LED module.
26W Compact Outdoor LED Driver
The T1 26W model uses 100–277Vac input and provides a 27–54Vdc output window with approximately 0.30–0.80A full-power current capability.
Its enclosure is approximately 108.5 × 62 × 32mm, making it particularly relevant to compact outdoor luminaires where internal power-supply space is limited.
Typical efficiency is approximately 86.5% with power factor above 0.95.
40W Compact Street and Tunnel Light Driver
The T1 40W model provides 27–56Vdc constant-current output with approximately 0.74–1.11A current capability.
The current product uses the same approximately 108.5 × 62 × 32mm compact enclosure direction as the 26W model while increasing available LED power to 40W.
This makes it suitable for compact street lights, tunnel fixtures, display lighting and other outdoor luminaires requiring more output without moving to a substantially larger driver platform.
60W 27–56V Compact LED Driver
The 60W 27–56Vdc T1 platform is designed for LED modules that require relatively higher current. Its current operating range extends from approximately 1.11A to 1.66A.
This model is relevant to compact LED boards using fewer series-connected LEDs and higher operating current while still requiring a 100–277Vac professional outdoor driver.
60W 54–85V Outdoor LED Driver
The second 60W T1 platform uses a 54–85Vdc output window with approximately 0.30–1.10A current capability.
Compared with the 27–56V version, this model is intended for a higher-voltage LED-string architecture operating at lower current.
Fixture designers should select between the two 60W options from the actual LED forward-voltage window and required current rather than simply specifying “60W driver.”
27–54V and 27–56V LED Drivers
T1 includes lower-voltage constant-current platforms around 27–56Vdc for compact LED modules.
The 26W model uses 27–54Vdc, while the 40W and one 60W model use 27–56Vdc. Their available current increases with power from 0.30–0.80A at 26W to as much as 1.66A on the 60W platform.
These models are suitable for compatible LED boards where the complete minimum-to-maximum forward-voltage range remains within the selected driver window.
54–85V LED Driver for Higher-Voltage LED Strings
T1 also provides a 54–85Vdc 60W configuration for compact fixtures that use a longer LED string and lower current.
This gives fixture manufacturers two different electrical architectures within the same 60W power class: 27–56V for higher current and 54–85V for higher LED-string voltage.
Compact 0–10V LED Drivers
Compatible T1 Type B configurations support dimming together with offline output-current programming. The broader T1 platform supports 0–10V control for compatible street, tunnel and commercial lighting systems.
0–10V allows a controller or sensor to adjust fixture output using a low-voltage analog control signal while the driver remains supplied from the main AC circuit.
The actual control range and low-end behavior should be validated with the selected driver configuration, controller and LED module.
PWM, Resistor and Timer Dimming
T1 supports several outdoor-lighting control methods depending on configuration.
| Control Method | Typical Application |
|---|---|
| 0–10V | Analog dimming for street, tunnel and commercial fixtures |
| PWM | Fixture controllers and automated lighting systems |
| Resistor Control | External resistance-based output adjustment |
| Timer Dimming | Scheduled nighttime street and outdoor-lighting profiles |
Control capability is configuration-dependent. Specify the required interface when requesting samples or production units.
Programmable Compact LED Drivers
Compatible T1 configurations support offline output-current programming. Supported operating parameters can be configured within the electrical limits of the selected model.
Programmability can be useful for OEM manufacturers developing several related compact fixtures. One driver platform may potentially support more than one fixture operating point when the programmed current remains within the approved voltage, power and thermal limits.
Programming requirements should be defined before production so driver settings, luminaire power and finished-product specifications remain consistent.
T1 Control Configurations: Type B, Type V and Type D
The “X” position used in T1 model codes represents the selected control configuration.
| Configuration | Function Direction |
|---|---|
| Type B | Dimmable with offline programmable output |
| Type V | Non-dimmable with potentiometer adjustment |
| Type D | DALI dimmable configuration |
For projects that specifically require a dedicated DALI-2 outdoor-driver family, compare
DALI-2 Outdoor LED Drivers
rather than assuming every T1 configuration uses the same digital-control implementation.
Compact Street Light LED Drivers
Smaller street-light fixtures often have limited internal space for the power supply while still requiring wide AC input, outdoor protection, surge capability and dimming.
T1 provides 26W to 60W options for compatible compact roadway luminaires. Model selection should consider the LED voltage and current together with enclosure space and the required control interface.

.
Compact LED Drivers for Tunnel Lighting
Small tunnel luminaires and auxiliary tunnel fixtures can require a compact power supply together with controlled output and robust environmental protection.
T1 provides 100–277Vac input, 26W–60W power classes and configurable control functions for compatible tunnel-lighting designs.
LED Drivers for Display and Auxiliary Outdoor Lighting
The T1 platform is also relevant to outdoor display lighting, auxiliary luminaires and other professional fixtures where full-size high-power street-light drivers would be unnecessarily large.
The 26W and 40W models are particularly useful for these applications because they combine lower output power with compact enclosure dimensions and professional outdoor protection.
IP65 and IP67 Compact Outdoor LED Drivers
Current T1 products provide IP65 / IP67 enclosure configurations for professional outdoor-lighting applications.
The driver IP rating applies to the driver enclosure or selected configuration. The finished luminaire must also use suitable connectors, cable entries, seals and housing construction to achieve the required environmental protection.
Confirm the exact IP configuration during project selection rather than assuming every ordered version is mechanically identical.
DM 6kV / CM 10kV Surge Protection
Current T1 technical specifications provide differential-mode surge protection up to 6kV and common-mode protection up to 10kV.
Surge capability is particularly relevant in outdoor lighting because long wiring runs, switching events and lightning-related disturbances can introduce electrical transients.
Driver-level surge protection should be coordinated with project grounding and any system-level surge-protection strategy.
SCP, OVP and OTP Protection
T1 includes short-circuit protection, over-voltage protection and over-temperature protection.
These functions help the driver respond to abnormal electrical or thermal conditions but do not replace correct LED-board design, fixture cooling, wiring or branch-circuit protection.
Power Factor and Efficiency
Current T1 products specify power factor above 0.95. Typical efficiency is approximately 86.5% for the 26W model and approximately 88% for the current 40W and 60W models.
At lower power levels, efficiency should be evaluated together with enclosure size, control capability, LED compatibility and thermal performance rather than as an isolated selection parameter.
T1 vs F1 Outdoor LED Drivers
T1 and F1 share the broader FAHOLD programmable outdoor-driver architecture but target different fixture power and mechanical requirements.
| Requirement | T1 | F1 |
|---|---|---|
| Power Direction | 26W–60W | 40W–400W |
| Rated Input | 100–277Vac | 100–277Vac |
| Main Advantage | Compact lower-power fixture integration | Broad power and LED voltage selection |
| Typical Application | Compact street, tunnel, display and auxiliary lighting | Street, tunnel, stadium and high-power outdoor lighting |
Choose T1 when fixture size and lower power are the primary requirements. For projects requiring more than 60W or a much broader choice of LED voltage platforms, compare
