Non-Isolated Horticulture LED Drivers for Commercial Grow Lighting

A non-isolated horticulture LED driver uses a power architecture without galvanic isolation between the AC input and LED output. This approach can support high conversion efficiency, compact mechanical integration and high power density when the complete grow-light fixture is specifically designed around a non-isolated LED power system.

FAHOLD non-isolated grow-light drivers cover compact inter-canopy lighting, commercial LED bar fixtures, high-power indoor grow lights and greenhouse top-light systems. Available platforms range from lower-power single-output drivers to programmable 1200W-class single-channel products and dual-channel horticulture drivers up to 1500W.

Non-isolated driver selection requires system-level engineering. The LED-board voltage, accessible parts, insulation, connectors, enclosure, grounding, channel architecture, control method and target certification must all be evaluated as part of the finished luminaire.

Non-Isolated vs Isolated Grow Light LED Drivers

Isolation topology is one of the first decisions when designing a professional horticulture fixture. An isolated driver provides galvanic separation between the mains input and LED output, while a non-isolated driver does not provide the same input-to-output isolation.

ArchitectureTypical AdvantageSelection Direction
Non-Isolated LED DriverHigh power density, compact integration and potentially very high conversion efficiencyFixtures engineered around protected high-voltage LED loads and a complete non-isolated safety architecture
Isolated LED DriverElectrical separation between AC input and LED outputFixtures where input-to-output isolation forms part of the electrical safety architecture

Neither topology should be selected from efficiency alone. The correct choice depends on the complete luminaire architecture, LED voltage, accessible components, enclosure design, target certification and installation environment.

Single-Channel and Multi-Channel Non-Isolated Grow Light Drivers

FAHOLD non-isolated horticulture products include both single-channel and multi-channel architectures. The correct structure depends on how the LED loads are electrically arranged inside the fixture.

ArchitectureTypical FixtureSelection Focus
Single-ChannelInter-canopy lights, LED bar fixtures and high-power grow lights using one primary regulated LED loadOutput-voltage window, current, total wattage, programming and dimming method
Multi-Channel / Dual-ChannelTop-grow and advanced horticulture fixtures using separate LED loads or auxiliary lighting channelsIndividual channel voltage, current, power allocation and independent control requirements

A high-wattage fixture does not automatically require multiple output channels. If the LED system operates as one electrical load, a single-channel platform may be more appropriate. Multi-channel drivers are relevant when two or more LED sections require separate power distribution or control.

Non-Isolated Grow Light Drivers from 60W to 1500W

The FAHOLD non-isolated horticulture portfolio covers substantially different fixture classes rather than one continuous driver family. Product selection should therefore begin with the application and LED architecture before narrowing by wattage.

Power DirectionTypical Product DirectionTypical Application
60W–320WR2-H and compact R2-based platformsInter-canopy lighting, linear horticulture fixtures and lower-power grow-light applications
400W–800WR4 high-power single-channel platformCommercial LED bar lights, indoor-grow fixtures and high-output horticulture luminaires
880W–1200WR4 / R6-V high-power platformsLarge indoor grow lights and greenhouse top-light systems
1500W ClassR6-V dual-channel platformVery high-power commercial top-grow fixtures requiring separate controlled outputs

Rated wattage is only one selection parameter. The LED forward-voltage window, required current, channel architecture and facility AC input must also match the selected driver.

120–277V, 200–277V and 480V Non-Isolated Grow Light Drivers

Commercial horticulture facilities use different AC distribution systems depending on region, facility scale and luminaire power. FAHOLD non-isolated platforms therefore cover several input-voltage architectures.

Rated Input DirectionTypical PlatformProject Direction
120–277VacR2-H / R2 / R4Commercial indoor grow lights, inter-canopy fixtures and broadly deployed horticulture luminaires
200–277VacR4E and selected high-power platformsCommercial high-power fixtures designed around 208V, 240V or 277V-class infrastructure
200–480VacR2-H high-voltage / R4-V / selected R6-VHigh-voltage horticulture systems including 347V and 480V-class installations
277–480VacSelected R2E-V and R6-V configurationsLarge greenhouse and commercial top-grow lighting systems

Always confirm the exact rated-input range of the selected product. A driver designed only for 120–277Vac operation should not be connected to a 347V or 480V supply.

R2-H Low-Power Drivers for Inter-Canopy Horticulture Lighting

Inter-canopy lighting places linear LED fixtures inside or between crop rows, where limited fixture space and relatively high LED-string voltage can create different driver requirements from traditional overhead grow lights.

FAHOLD R2-H non-isolated single-channel products use a 180–260Vdc LED output platform. The current 120–277Vac group covers 60W, 100W, 150W, 200W, 240W and 320W, while the 200–480Vac branch includes 60W, 120W, 150W and 200W options.

This makes R2-H relevant to slim inter-canopy and linear horticulture fixtures where lower power, high LED-string voltage and compact driver integration are priorities.

R4 High-Efficiency Non-Isolated Grow Light Drivers

R4 is the primary FAHOLD high-power non-isolated single-channel platform. The family covers 400W to 1200W and is available across 120–277Vac, 200–277Vac and 200–480Vac rated-input branches.

Current R4 platforms use a 210–360Vdc output window for high-voltage LED-string architectures. The slim linear enclosure is designed for high power density in grow-light and LED bar fixtures where internal installation space is limited.

Selected R4 models reach typical efficiency up to approximately 97%, making the platform particularly relevant to professional grow lights that operate for long daily cycles and require low driver losses.

For complete technical specifications, review the

R4 High-Power Non-Isolated Grow Light LED Driver Series

Programmable Non-Isolated Grow Light Drivers

Selected FAHOLD non-isolated platforms support offline programmable output. Programming allows supported electrical parameters to be configured within the operating limits of the driver to match different LED boards, fixture wattages or OEM product variants.

This can help horticulture-lighting manufacturers standardize one driver platform across several fixture SKUs rather than maintaining a separate power supply for every current or wattage target.

The programmed operating point must remain inside the permitted voltage, current, power and thermal limits of the selected driver.

0–10V, PWM and Resistor Dimming for Commercial Grow Lights

Commercial cultivation systems often need adjustable light output for plant-growth stages, daylight integration, environmental-control strategies or facility energy management. Depending on series and configuration, FAHOLD non-isolated horticulture drivers support 0–10V, PWM and resistor-based dimming.

Control MethodTypical UseSelection Consideration
0–10VCommercial greenhouse and indoor-grow controllersConfirm signal range, wiring and controller compatibility.
PWMFixture controllers and automated horticulture systemsConfirm signal requirements, frequency and driver compatibility.
Resistor / RxExternal resistance-based output adjustmentConfirm the supported resistance range and control-interface architecture.

Available control methods differ between product families. The actual greenhouse controller or fixture interface should therefore be specified during driver selection.

Dim-to-Off for Controlled-Environment Agriculture

A complete dark period can be important in controlled-environment agriculture. Selected programmable FAHOLD non-isolated platforms support Dim-to-Off so the LED output can shut down fully at the lower control threshold instead of producing residual visible light.

The controller, driver and LED load should be tested together when precise low-end control and complete shutdown are project requirements.

Dual-Channel Drivers for Commercial Top-Grow Lights

Some high-power horticulture fixtures use separate primary and auxiliary LED loads rather than one combined output. A dual-channel architecture allows these sections to be powered and controlled independently.

FAHOLD R6-V is a high-power non-isolated dual-channel platform for commercial top-grow lighting. Current models cover 880W, 1000W, 1200W and 1500W, with 200–480Vac or 277–480Vac rated-input platforms depending on model.

R6-V provides independent control of both output channels. The primary P1 channel uses a 150–500Vdc output platform, while the P2 auxiliary channel uses 30–150Vdc. Compatible configurations support 0–10V and PWM dimming together with optional dynamic channel-power allocation.

For high-voltage dual-channel projects, review the

R6-V Dual-Channel Grow Light LED Driver Series
.

Dynamic Power Allocation in Dual-Channel Grow Lights

A multi-channel grow-light fixture may not require maximum power from every LED section at the same time. On compatible R6-V configurations, dynamic power allocation can shift available power between auxiliary and primary outputs while remaining within the total power limit of the driver.

This can provide additional flexibility for horticulture fixtures that use different LED spectra, supplemental channels or crop-specific lighting strategies.

High-Efficiency Grow Light Drivers for Long Operating Cycles

Grow-light drivers can operate for many hours per day, so conversion efficiency directly affects electrical losses and heat generated inside or around the fixture.

FAHOLD non-isolated platforms are designed around high-efficiency power conversion, with selected R4 models reaching approximately 97% typical efficiency. The practical efficiency of the complete lighting system still depends on input voltage, LED operating point, current, temperature and fixture thermal design.

Efficiency should therefore be compared together with power factor, output range, control capability and thermal performance rather than used as the only product-selection criterion.

IP-Rated Non-Isolated Horticulture LED Drivers

Environmental requirements vary significantly between inter-canopy fixtures, indoor grow rooms and greenhouse top-light systems. FAHOLD non-isolated product families therefore use different enclosure and ingress-protection options.

Platform DirectionProtection DirectionTypical Application
R2 / R2E-based productsIP42 with IP67 options on applicable modelsInter-canopy and compact horticulture fixture architectures
R4IP65High-power grow-light and commercial LED bar fixtures
R6-VIP65High-power commercial top-grow lighting

The driver IP rating applies only to the driver enclosure or configured product. Connectors, cables, seals, fixture housing, mounting orientation and the complete luminaire must also be designed for the actual horticulture environment.

Non-Isolated LED Drivers for Inter-Canopy Lighting

Inter-canopy fixtures operate closer to the crop canopy and often require a slim mechanical profile. R2-H provides lower-power 180–260Vdc constant-current platforms that are suited to this style of linear horticulture fixture.

When selecting an inter-canopy driver, consider fixture dimensions, LED-string voltage, required current, humidity, connector architecture and the AC distribution used across the cultivation facility.

Non-Isolated Drivers for LED Bar Grow Lights

High-power LED bar fixtures benefit from slim drivers with high conversion efficiency and programmable output. The R4 platform is designed around this requirement, combining a linear enclosure, 400W–1200W power classes and a 210–360Vdc high-voltage LED output architecture.

Offline programming and compatible 3-in-1 dimming allow the power platform to be adapted to different commercial grow-light designs within the supported electrical range.

Non-Isolated Drivers for Greenhouse Top Lighting

Large greenhouse top-light fixtures may require several hundred watts to more than one kilowatt of LED power together with 277V, 347V or 480V-class facility distribution.

For single-load fixtures, high-voltage R4-V platforms can provide a programmable non-isolated solution. For fixtures using independently controlled primary and auxiliary loads, R6-V provides a dual-channel architecture with high-voltage input capability.

How to Select a Non-Isolated Horticulture LED Driver

  1. Confirm that a non-isolated architecture is appropriate.
    Review the complete luminaire safety design, accessible parts, LED voltage and certification requirements.
  2. Identify the fixture application.
    Determine whether the project is an inter-canopy light, LED bar fixture, indoor grow light or greenhouse top light.
  3. Confirm the facility AC input.
    Identify whether the system uses 120V, 208V, 240V, 277V, 347V, 480V or another supported supply.
  4. Define the LED voltage window.
    Provide the minimum, nominal and maximum forward voltage of each LED load.
  5. Confirm the required output current.
    The current range must match the LED-board architecture at the intended operating power.
  6. Select single-channel or multi-channel architecture.
    Base the channel structure on the actual number of independently powered or controlled LED loads.
  7. Calculate maximum fixture wattage.
    Use the actual electrical LED load rather than marketing fixture wattage alone.
  8. Define the dimming method.
    Specify 0–10V, PWM, resistor control or another required interface according to the selected platform.
  9. Determine whether offline programming is required.
    Programmable platforms can simplify OEM product families using multiple power or current configurations.
  10. Review IP, thermal and certification requirements.
    Evaluate humidity, ambient temperature, connectors, enclosure construction, heat management and target-market compliance.
