Isolated Single-Channel LED Drivers for Grow Lights
A single-channel horticulture LED driver provides one regulated output for one primary LED load or electrically combined LED-board system. This architecture is widely used in quantum-board grow lights, propagation fixtures, commercial indoor-grow luminaires and high-power horticulture systems where the fixture is designed around one main constant-current output.
FAHOLD isolated single-channel grow-light drivers combine input-to-output electrical isolation with several power, voltage and control platforms. The current product range covers compact 40W fixtures through professional 1500W grow lights, allowing fixture manufacturers to select the driver according to the actual LED-board voltage, output current, facility input voltage and control strategy.
Single-channel does not mean low power. A single regulated output can be used for both compact horticulture fixtures and very high-power LED boards when the voltage, current, wiring and thermal architecture of the luminaire are designed accordingly.
Single-Channel vs Multi-Channel Grow Light Drivers
The choice between single-channel and multi-channel power architecture should be based on the electrical design of the grow-light fixture rather than total wattage alone.
| Architecture | Typical Fixture Design | Selection Focus |
|---|---|---|
| Single-Channel | Quantum boards, propagation fixtures and high-power grow lights using one primary regulated LED load | LED voltage window, output current, total wattage and dimming method |
| Multi-Channel | Fixtures using separate LED loads, spectral sections or independently managed lighting zones | Individual channel voltage, current, power distribution and control strategy |
If all LED boards in the fixture operate as one electrical load, a single-channel driver can provide a simpler power architecture. When separate LED loads require independent power distribution or control, a multi-channel platform may be more appropriate.
For those applications, compare

Choose a Single-Channel Grow Light Driver by Power Range
FAHOLD isolated single-channel platforms cover a wide range of horticulture fixture power levels. The appropriate product family changes significantly between compact quantum-board lighting and high-output commercial grow lights.
| Power Range | Typical Platform | Typical Fixture Direction |
|---|---|---|
| 40W–100W | F1-H | Seedling lights, propagation fixtures, compact quantum boards and small indoor grow lights |
| 150W–320W | F1-H | Medium quantum boards, vertical-farm fixtures and compact commercial horticulture luminaires |
| 650W–800W | H2 / H2E | Commercial bar lights, indoor-grow fixtures and greenhouse lighting |
| 1000W–1200W | H2 / H2E | High-output commercial horticulture and greenhouse fixtures |
| 1300W–1500W | H2E | Very high-power grow-light systems using 200–277Vac facility infrastructure |
Driver wattage alone is not sufficient for product selection. The connected LED load must also remain within the output-voltage and current range of the selected model across expected operating temperature and production tolerances.
100–277V F1-H Drivers for Quantum Boards and Compact Grow Lights
F1-H is the lower- and medium-power platform within the isolated single-channel category. It covers 40W to 320W with 100–277Vac rated input and 27–54V or 27–56V output-voltage ranges.
The series is designed around compact horticulture fixture integration and includes built-in five-step knob dimming, Dim-to-Off, plug-and-play AC and DC connection options and IP67 enclosure protection.
This makes F1-H particularly relevant to quantum-board grow lights, propagation fixtures, vertical-farm racks and other products where simple installation and local output adjustment are important.

120–277V H2 High-Power Single-Channel Grow Light Drivers
H2 extends the isolated single-channel architecture into higher-power commercial horticulture fixtures. Current H2 models use 120–277Vac input and cover 650W, 800W, 1000W and 1200W power classes.
Available output platforms include 36–56V, 42–56V and 42–62V, with high-current configurations designed for professional LED boards used in commercial grow lights and greenhouse luminaires.
Unlike the simpler F1-H architecture, H2 supports offline programmable output, adaptive output-voltage operation and compatible 0–10V / PWM / resistor-based control. This allows the same driver platform to support different fixture power and current requirements within its rated operating range.

H2 Single-Channel Grow Light LED Driver Series
.
200–277V H2E Grow Light Drivers from 800W to 1500W
H2E is the 200–277Vac branch of the high-power single-channel horticulture platform. It is intended for commercial grow-light fixtures that operate from higher-voltage facility infrastructure and require one dedicated high-current isolated LED output.
Current H2E products cover 800W, 1000W, 1200W, 1300W and 1500W power classes. The series uses 42–56V and 42–62V output platforms, with the 1500W configuration reaching output-current capability up to approximately 31A.
H2E also provides offline programming, 0–10V / PWM / Rx dimming, Dim-to-Off and optional fixture-integration interfaces for demanding commercial horticulture projects.
See the
H2E 200–277Vac Grow Light LED Driver Series
for complete 800W–1500W model specifications.
Choose by LED Output-Voltage Window
The output-voltage window is one of the most important specifications when matching a constant-current driver to a horticulture LED board. The complete LED forward-voltage range must overlap correctly with the supported driver output range.
| Output Platform | Typical Series | Typical Fixture Direction |
|---|---|---|
| 27–54V | F1-H | Lower- and medium-power quantum boards and compact LED modules |
| 27–56V | F1-H | Higher-power F1-H quantum-board and horticulture fixtures |
| 36–56V | H2 | High-current commercial LED-board architecture |
| 42–56V | H2 / H2E | High-power grow-light LED boards and commercial horticulture fixtures |
| 42–62V | H2 / H2E | Very high-power LED-board platforms requiring an extended voltage window |
Do not select a driver simply because its maximum wattage matches the fixture. Provide the minimum, nominal and maximum LED forward voltage together with the required current so the operating point can be checked against the driver window.
High-Current LED Drivers for Commercial Grow Lights
Single-channel horticulture fixtures can require substantial DC current as fixture wattage increases while the LED operating voltage remains relatively low. H2 and H2E are designed around this type of high-current grow-light architecture.
Current H2 models extend to approximately 24A depending on model, while the 1500W H2E platform reaches up to approximately 31A. At these current levels, LED-board design, output cables, connectors, PCB current paths and thermal management all become important parts of the complete luminaire system.
The driver output-current capability should therefore be matched to the complete fixture architecture rather than treated as an isolated product specification.
Programmable Single-Channel Grow Light LED Drivers
Offline programmable output allows supported H2 and H2E models to be configured for different LED-board current or fixture-power requirements within the electrical limits of the selected driver.
This can help OEM grow-light manufacturers reduce the number of unique power platforms used across a product family. Several fixture SKUs may share one driver hardware platform while using different programmed operating points when the required voltage, current and power remain within the approved range.
Programming requirements should be defined during product development so the correct current limits and power settings can be applied consistently during production.
0–10V, PWM and Rx Dimming for Horticulture Fixtures
H2 and H2E support compatible 3-in-1 control using 0–10V, PWM and resistor-based Rx input. These control methods allow commercial grow-light output to be adjusted according to cultivation stage, daylight availability, facility energy strategy or centralized environmental-control systems.
| Control Method | Typical Application | What to Confirm |
|---|---|---|
| 0–10V | Greenhouse and indoor-grow control systems | Control signal range, wiring and controller compatibility |
| PWM | Fixture controllers and automation systems | Signal level, PWM requirements and driver compatibility |
| Rx / Resistor | External resistance-based output adjustment | Supported resistance range and control-interface requirements |
F1-H uses a different control strategy based primarily on built-in knob dimming, so the required control architecture should be defined before choosing between F1-H and the H2 family.
Dim-to-Off and No-Afterglow Operation
A true off state can be important in horticulture lighting because some cultivation schedules require complete darkness. Residual LED output after a dimming command reaches minimum level can create visible afterglow when the grow light should be off.
F1-H supports Dim-to-Off through its local control architecture, while H2 and H2E support Dim-to-Off together with compatible external dimming control. The H2 family is specifically designed for shutdown without afterglow on applicable configurations.
IP67 vs IP65 Single-Channel Grow Light Drivers
The F1-H and H2-family platforms use different enclosure strategies according to their application and power level.
| Protection | Platform | Typical Application |
|---|---|---|
| IP67 | F1-H | Quantum boards, compact grow lights and horticulture fixtures requiring greater ingress protection |
| IP65 | H2 / H2E | High-power commercial grow lights and greenhouse fixtures using protected driver integration |
The driver IP rating applies to the driver enclosure itself. Connectors, cable seals, fixture housing, mounting orientation, thermal design and other system components must also be suitable for the actual horticulture environment.
Plug-and-Play vs Programmable Grow Light Driver Platforms
F1-H and H2/H2E solve different fixture-design problems even though all three belong to the isolated single-channel category.
| Requirement | F1-H | H2 / H2E |
|---|---|---|
| Typical Power | 40W–320W | 650W–1500W |
| Primary Positioning | Compact plug-and-play horticulture driver | High-power programmable grow-light driver |
| Control Direction | Built-in knob dimming | 0–10V / PWM / Rx external control |
| Programming | Fixture-level configuration focused on plug-and-play integration | Offline programmable output for OEM fixture matching |
| Ingress Protection | IP67 | IP65 |
Choose F1-H when compact size, local control and simplified fixture connection are priorities. Choose H2 or H2E when the project requires substantially higher power, programmable output and external commercial lighting control.
Surge Protection for High-Power Grow Light Drivers
Commercial horticulture lighting can operate on large electrical systems where switching events and transients must be considered. H2 and H2E provide differential-mode surge protection up to 6kV and common-mode protection up to 10kV, together with short-circuit, over-voltage and over-temperature protection.
Driver-level protection does not replace correct facility grounding, branch-circuit design or system-level surge protection. The complete grow-light installation should be engineered according to the electrical environment of the facility.
How to Select an Isolated Single-Channel Grow Light Driver
- Confirm the facility AC input.
Determine whether the fixture needs 100–277Vac, 120–277Vac or 200–277Vac operation. - Define the LED forward-voltage window.
