H2E Isolated Grow Light Drivers (200-277Vac)
FAHOLD H2E isolated single-channel grow light drivers are designed for high-power commercial horticulture fixtures operating from 200–277Vac input. The series provides programmable constant-current output for professional indoor grow lights, greenhouse fixtures and high-output LED horticulture systems from 800W to 1500W.
Current H2E models use 42–56V or 42–62V output platforms with high-current capability up to 31A depending on model. Compatible configurations support offline programming, adaptive output-voltage operation, 0–10V / PWM / resistor control and Dim-to-Off without afterglow.
Compare the five H2E models below by wattage, LED voltage window, output-current range and control requirements. FAHOLD also supports driver matching, programming requirements, datasheets, samples and OEM/ODM grow-light projects.
H2E 200–277V High-Power Grow Light LED Drivers
FAHOLD H2E is a high-power isolated single-channel LED driver platform developed for professional horticulture fixtures that require one regulated constant-current output and a dedicated 200–277Vac input architecture. The current series covers 800W, 1000W, 1200W, 1300W and 1500W grow-light applications.
H2E combines isolated architecture, programmable output, adaptive output-voltage operation and flexible lighting control for commercial indoor-grow, greenhouse and controlled-environment agriculture fixtures. The driver should be selected from the LED-board voltage window, required operating current, maximum fixture power and control architecture rather than nominal wattage alone.
Compare H2E 800W to 1500W Grow Light Driver Models
The current H2E range provides five high-power configurations. Four models use a 42–56V LED output platform, while the 1500W version extends the upper voltage limit to 62V.
| Power Class | Output Voltage | Output Current | Typical Efficiency | Typical Application |
|---|---|---|---|---|
| 800W | 42–56V | 7.5–16.7A | 94% | Commercial indoor grow lights and high-output horticulture fixtures |
| 1000W | 42–56V | 10.0–21.0A | 94% | High-power commercial grow lights and greenhouse fixtures |
| 1200W | 42–56V | 13.0–26.0A | 95% | Very high-output horticulture and greenhouse lighting systems |
| 1300W | 42–56V | 13.0–26.0A | 95% | High-intensity commercial grow-light platforms |
| 1500W | 42–62V | 14.0–31.0A | 95% | Ultra-high-power grow-light and professional horticulture fixtures |
The correct model should be selected from the actual LED electrical load. The complete LED voltage and current operating range must remain inside the driver's supported window under normal temperature, dimming and production tolerances.
200–277Vac Input for Commercial Horticulture Lighting
All current H2E models use a 200–277Vac rated-input platform. This makes the series particularly relevant to commercial horticulture facilities designed around higher-voltage AC distribution rather than standard residential mains.
The AC input and LED output requirements should be evaluated separately. A fixture may receive 208Vac, 240Vac or 277Vac from the facility while the driver supplies regulated 42–56V or 42–62V constant-current power to the LED board.
For projects that also need operation from nominal 120Vac supplies, compare the
H2 120–277Vac Grow Light Drivers

42–56V and 42–62V High-Current LED Driver Platforms
H2E is designed around relatively low-voltage, high-current horticulture LED-board architectures. Most current models use a 42–56V output window, while the 1500W platform extends to 42–62V.
| Output Platform | Power Classes | Selection Direction |
|---|---|---|
| 42–56V | 800W / 1000W / 1200W / 1300W | High-current commercial horticulture LED boards operating within a 42–56V forward-voltage window |
| 42–62V | 1500W | Very high-power LED-board systems requiring additional voltage headroom and up to 31A output capability |
For accurate pre-selection, provide the LED board's minimum, nominal and maximum forward voltage together with its required current. Wattage alone cannot confirm compatibility between the LED board and driver.
High-Current Grow Light Drivers Up to 31A
As horticulture fixture power increases while the LED voltage remains in the 42–62V range, the required DC output current becomes substantial. H2E is specifically designed for this type of high-current single-channel architecture.
The current product family ranges from approximately 16.7A maximum on the 800W model to 31A on the 1500W platform. At these current levels, output cables, connectors, PCB current paths, LED-board terminals and thermal design become critical parts of the finished grow-light system.
The driver current specification should therefore be evaluated together with the complete electrical and mechanical fixture design.
Programmable H2E Horticulture LED Drivers
H2E supports offline programmable output on compatible configurations. Supported electrical parameters can be configured within the operating limits of the selected model to match different LED-board currents, fixture wattages or OEM product variants.
Programmability can reduce the number of unique driver platforms required across a grow-light product family. Several fixture SKUs may share the same H2E hardware direction while using different programmed current or power settings, provided the configured operating point remains within the approved voltage, current and thermal limits.
Programming requirements should be defined during product development so production settings, fixture labels and final electrical specifications remain consistent.
Adaptive Output Voltage for Horticulture LED Boards
H2E supports adaptive output-voltage operation within its rated electrical window. This allows the driver to accommodate LED-board forward-voltage variation instead of relying on one fixed output-voltage point.
LED forward voltage can vary with board design, operating current, temperature and component tolerance. For this reason, the driver should be matched to the complete LED operating range rather than only the nominal voltage printed on the fixture specification.
0–10V, PWM and Rx Dimming for Commercial Grow Lights
Compatible H2E configurations support 3-in-1 dimming using 0–10V, PWM and resistor-based Rx control. These control methods are widely used in commercial horticulture systems where light output must respond to crop stage, facility schedules, energy strategy or centralized environmental controls.
| Control Method | Typical Application | Selection Consideration |
|---|---|---|
| 0–10V | Greenhouse and commercial grow-light control systems | Confirm signal range, control wiring and controller compatibility. |
| PWM | Fixture controllers and automated horticulture systems | Confirm PWM signal requirements, frequency and driver compatibility. |
| Rx / Resistor | External resistance-based output adjustment | Verify the supported resistance range and control-interface requirements. |
The control protocol should be verified as a complete system. A driver and controller can both be described as 0–10V or PWM products while still having different signal or wiring requirements.
Type B Dimming and Non-Dimming H2E Configurations
The H2E product-code structure supports both dimmable and non-dimmable configurations. Type B identifies the 3-in-1 dimming version with 0–10V / PWM / Rx control, while the blank dimming code identifies fixed-output operation.
| Configuration | Control | Typical Requirement |
|---|---|---|
| Type B | 0–10V / PWM / Rx 3-in-1 dimming | Commercial grow lights connected to external controllers or centralized horticulture-control systems |
| Non-Dimming | Fixed-output operation | Grow-light fixtures that do not require external intensity control |
Specify the required dimming configuration when requesting samples or quotations rather than assuming every H2E model includes the same control interface.
Dim-to-Off Without LED Afterglow
Compatible H2E dimmable configurations support Dim-to-Off operation without afterglow. This allows the LED output to shut down completely at the lower control threshold rather than leaving visible residual light.
True off-state operation can be important in horticulture facilities where crop schedules require defined dark periods. The controller, driver and LED load should still be evaluated together during fixture validation.
RJ12, Knob Dimmer and 12V Auxiliary Output Options
H2E provides optional fixture-integration configurations for OEM grow-light manufacturers.
- RJ12 + knob configuration: supports compatible control connections together with local fixture-level adjustment.
- 12Vdc auxiliary output: provides auxiliary low-voltage power for compatible fixture-control electronics or accessories.
These functions are configuration-dependent and should be defined as part of the project specification rather than assumed to be standard on every H2E model.
94–95% Typical Efficiency for High-Power Grow Lighting
Current H2E technical data lists typical efficiency of approximately 94% on the 800W and 1000W models and approximately 95% on the 1200W, 1300W and 1500W platforms. Typical power factor is greater than 0.95 across the current model table.
Efficiency is especially important in high-power horticulture lighting because driver losses become heat that must be managed by the luminaire and facility. Actual system efficiency depends on input voltage, LED operating voltage, current, temperature and the selected driver model.
IP65 Grow Light Drivers for Commercial Horticulture
All current H2E models in this range use an IP65 enclosure platform for professional horticulture and high-power lighting applications. This provides protection against dust and moisture within the specified enclosure conditions.
IP65 applies to the driver itself and does not automatically define the environmental rating of the finished grow-light fixture. Connectors, cable entries, seals, housing, mounting orientation, humidity and thermal conditions must also be evaluated.
Surge and Electrical Protection for High-Power Grow Lights
H2E provides 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 should be combined with correct facility grounding, branch-circuit protection and system-level surge design in commercial horticulture installations.
Applications for H2E 200–277V Grow Light Drivers
Commercial Indoor Grow Lights
H2E is suitable for high-power indoor cultivation fixtures where the facility uses 200–277Vac distribution and the luminaire is designed around one high-current regulated LED output.
Greenhouse Lighting Fixtures
Commercial greenhouse fixtures operating from 208V, 240V or 277V-class infrastructure can use the H2E platform when the LED voltage, current and maximum fixture power match the selected driver.
1000W–1500W High-Output Grow Lights
The upper H2E power classes are intended for professional grow-light systems requiring very high LED output from one isolated constant-current channel. These applications require careful management of current, connectors, cabling and fixture heat.
How to Select the Right H2E Grow Light Driver

Verify the applicable safety, EMC and finished-luminaire requirements for the destination market.
H2E vs H2 Grow Light Drivers
H2E and H2 share the same broader isolated programmable single-channel architecture but are designed for different AC input and power requirements.
| Platform | Rated Input | Power Range | Typical Selection Scenario |
|---|---|---|---|
| H2 | 120–277Vac | 650W–1200W | Projects requiring broad input compatibility including nominal 120Vac operation |
| H2E | 200–277Vac | 800W–1500W | Higher-power commercial grow-light systems designed around 200–277Vac facility infrastructure |
Choose H2E when the facility is designed around 200–277Vac input and the fixture requires power up to 1500W. Choose H2 when operation from nominal 120Vac is also required or the fixture falls within the 650W–1200W H2 range.
