Non-Isolated Dual-Channel LED Drivers for Grow Lights

A multi-channel horticulture LED driver provides two or more controlled outputs from one driver platform so separate LED loads, fixture sections or spectral groups can be powered and managed independently. This architecture is useful when a grow-light fixture cannot be treated as one single electrical load.

FAHOLD non-isolated multi-channel grow-light drivers cover both compact dual-output horticulture fixtures and very high-power commercial top-grow systems. The current portfolio includes R2 / R2E-V platforms for inter-lighting and under-canopy applications together with R6-V high-power dual-channel drivers for greenhouse and commercial top lighting.

The correct product should be selected from the electrical requirements of each LED channel, not only from total fixture wattage. Input voltage, channel voltage window, current, channel power, dimming method, enclosure protection and fixture safety architecture must all be considered together.

Why Use a Dual-Channel Grow Light Driver?

A dual-channel driver is useful when one horticulture luminaire contains two LED loads that need different electrical operating points or separate control. Examples include a primary growing-light channel combined with a supplemental spectral channel, inter-lighting fixtures with a secondary LED section or commercial top-grow lights that require independent control over two LED loads.

Instead of installing two completely independent drivers, a properly designed dual-channel platform can integrate the two outputs into one power architecture while preserving independent channel control.

The number of channels should be determined by the fixture electrical design. A dual-channel driver is not automatically better than a single-channel driver for a high-power luminaire.

Compact Dual-Channel vs High-Power Dual-Channel Grow Light Drivers

The current FAHOLD non-isolated multi-channel range contains two distinct product directions. Choosing between them should begin with the type of horticulture fixture being developed.

Platform DirectionCurrent Power ClassesRated InputTypical Application
R2 / R2E-V150W–300W primary-channel platforms120–277Vac / 277–480VacInter-lighting, under-canopy lighting, linear horticulture fixtures and supplemental LED loads
R6-V880W–1500W total driver platforms200–480Vac / 277–480VacCommercial top-grow lights, greenhouse fixtures and very high-power dual-channel horticulture systems

R2 / R2E-V is the more appropriate direction when mechanical size and compact dual-output integration are important. R6-V is designed for substantially higher fixture power and high-voltage commercial grow-light infrastructure.

R2 Dual-Channel Drivers for Inter-Lighting and Under-Canopy Fixtures

The R2 dual-channel horticulture platform is designed for slim lighting fixtures installed close to or within the crop canopy. These applications often require a narrow mechanical format and two electrically different LED loads inside one fixture.

The current 150W R2 dual-channel model uses 120–277Vac input and combines a 180–260Vdc primary channel with a 27–54Vdc auxiliary channel. Channel 1 provides the primary horticulture output, while Channel 2 supplies a lower-power secondary LED load.

Available 120–277Vac products currently include primary-channel power classes of 150W and 240W, with auxiliary-channel power designed for secondary horticulture lighting requirements.

This architecture is particularly relevant to inter-lighting, under-canopy lighting and supplemental horticulture fixtures where a separate secondary LED section must be integrated into a narrow luminaire.

277–480V R2E-V Dual-Channel Drivers

For facilities using higher-voltage AC distribution, the R2E-V dual-channel platform extends the compact horticulture architecture into 277–480Vac systems.

Current R2E-V products include 150W and 300W primary-channel configurations with separate lower-power auxiliary outputs. These products allow compact dual-channel fixtures to be integrated into high-voltage commercial greenhouse or horticulture electrical infrastructure without moving directly to an 880W+ top-grow platform.

This makes R2E-V useful when the fixture itself remains relatively compact but the facility distributes power at 277V, 347V or 480V-class voltages.

R6-V High-Power Dual-Channel Grow Light Drivers

R6-V is the high-power branch of the FAHOLD non-isolated multi-channel horticulture portfolio. It is developed for commercial LED top-grow lights and other high-output fixtures requiring two independently controlled constant-current channels.

Current R6-V products include 880W, 1000W, 1200W and 1500W models. The 880W and 1000W platforms use 200–480Vac rated input, while the 1200W and 1500W models use 277–480Vac input.

R6-V Power ClassRated InputPrimary Output PlatformAuxiliary Output Platform
880W200–480VacP1: 150–500VdcP2: 30–150Vdc
1000W200–480VacP1: 150–500VdcP2: 30–150Vdc
1200W277–480VacP1: 150–500VdcP2: 30–150Vdc
1500W277–480VacP1: 150–500VdcP2: 30–150Vdc

The large difference between the P1 and P2 voltage windows allows the platform to support a high-power primary LED load together with a separate auxiliary LED section using a different electrical architecture.

For detailed model comparison, review the

Independent Dual-Channel Control

Independent channel control allows the two LED outputs to respond separately rather than forcing both loads to operate at the same intensity.

This is valuable in horticulture fixtures that combine different LED groups or spectral functions. Fixture engineers can design separate control behavior for the primary and auxiliary channels while keeping both outputs within one driver platform.

The required output voltage, current and power for each channel should be specified separately during product selection. Providing only the total fixture wattage is not sufficient to match a dual-channel driver accurately.

0–10V and PWM Dimming for Dual-Channel Grow Lights

Selected FAHOLD dual-channel horticulture platforms support 0–10V and PWM control. These interfaces allow commercial grow-light systems to adjust lighting output according to crop stage, environmental strategy, daylight availability or facility-control schedules.

Control MethodTypical ApplicationWhat to Confirm
0–10VCommercial greenhouse and indoor-grow controllersSignal range, channel wiring and controller compatibility
PWMFixture controllers and automated horticulture systemsSignal level, frequency and driver interface requirements

R6-V supports independent 0–10V / PWM control of its two outputs on compatible configurations. R2 dual-channel products also use compatible 0–10V / PWM control architectures depending on configuration.

Dynamic Channel Power Allocation

Some horticulture fixtures do not require maximum output from both LED channels at the same time. In these systems, fixed power allocation can leave available driver capacity unused.

Compatible R6-V configurations support dynamic channel power transfer, allowing available power to be redistributed between the auxiliary and primary outputs while remaining within the total power limit of the driver.

This can be useful for top-grow luminaires that adjust the balance between primary and supplemental LED sections according to crop recipe or operating mode.

Primary and Auxiliary LED Channels in Grow-Light Fixtures

A dual-channel horticulture fixture commonly uses one channel as the main growing-light output and another as an auxiliary or supplemental LED load. The two channels may use different LED string voltages, currents and power levels.

This architecture can support supplemental spectrum, inter-lighting functions or other fixture-specific LED groups without requiring every load to share one electrical operating point.

Channel purpose is determined by the final luminaire design. The driver itself should therefore be matched from the actual electrical requirements of P1 / CH1 and P2 / CH2 rather than from a generic spectrum label.

120–277V, 200–480V and 277–480V Dual-Channel LED Drivers

FAHOLD non-isolated multi-channel products span several commercial AC input platforms.

Rated InputPlatform DirectionTypical Project
120–277VacR2 dual-channelInter-lighting and compact horticulture fixtures using common commercial AC distribution
200–480VacSelected R6-V modelsHigh-power top-grow fixtures operating across broad commercial and industrial voltage systems
277–480VacR2E-V and selected R6-V modelsHigh-voltage greenhouse and commercial horticulture infrastructure

The exact rated-input range must be confirmed for the selected model. Do not assume every product in the multi-channel category supports the same AC supply voltage.

347V and 480V Dual-Channel Grow Light Drivers

Large commercial cultivation facilities can use 347V or 480V-class electrical distribution to supply lighting systems efficiently across large areas. R2E-V and R6-V provide high-voltage input directions for compatible horticulture projects.

The correct platform depends heavily on fixture power. A compact 150W or 300W multi-channel fixture has very different electrical and mechanical requirements from an 880W to 1500W commercial top-grow luminaire even when both operate from a high-voltage facility supply.

IP42, IP67 and IP65 Multi-Channel Driver Options

Environmental protection differs between the compact and high-power platforms.

PlatformProtection DirectionTypical Application
R2 / R2E-VIP42 standard with IP67 option on applicable configurationsInter-lighting, under-canopy and compact horticulture fixtures
R6-VIP65Commercial high-power top-grow and greenhouse fixtures

The driver enclosure rating does not automatically define the environmental rating of the complete grow-light fixture. Connectors, cables, seals, luminaire housing and mounting conditions must also be designed for the intended environment.

Efficiency for Dual-Channel Horticulture Lighting

Driver efficiency is especially important in grow-light systems because fixtures can operate for long daily cycles. Electrical losses become both energy cost and heat that must be managed by the luminaire and cultivation facility.

Current compact R2 / R2E-V dual-channel models reach typical efficiency values in approximately the 93.5% to 95% range depending on configuration. R6-V models reach approximately 95% to 96% typical efficiency depending on power level and operating point.

Efficiency should be considered together with channel architecture, output voltage, current, ambient temperature and thermal design rather than used as the only product-selection criterion.

Surge and Protection Functions for Commercial Grow Lighting

Commercial horticulture installations can be exposed to switching transients and demanding electrical conditions. Current R2 dual-channel and R6-V platforms include surge and electrical protection functions designed for professional lighting systems.

R6-V provides DM 8kV / CM 8kV surge protection together with short-circuit, over-current and over-temperature protection. Internal driver protection should still be combined with correct facility grounding, branch-circuit protection and system-level surge design.

Dual-Channel Drivers for Inter-Canopy and Under-Canopy Lighting

Inter-canopy and under-canopy luminaires operate in space-constrained locations close to crop foliage. These fixtures benefit from a narrow mechanical format and a power architecture capable of supplying primary and supplemental LED loads from one driver.

The compact R2 / R2E-V dual-channel platforms are particularly relevant to these applications because they combine separate LED outputs with narrow driver construction and commercial AC input options.

Dual-Channel Drivers for Commercial Top-Grow Lights

High-power top-grow fixtures require a substantially different power platform. R6-V covers 880W through 1500W and provides separate high-voltage primary and auxiliary outputs for commercial horticulture luminaires.

Independent channel dimming and optional dynamic power transfer provide additional flexibility for top-grow fixtures that use two controlled LED sections within one luminaire.

How to Select a Non-Isolated Multi-Channel Grow Light Driver

  1. Confirm that a non-isolated architecture is appropriate.
    Review LED voltage, accessible parts, insulation, enclosure construction and certification requirements.
  2. Define each LED channel separately.
    Provide the minimum and maximum voltage, current and maximum power required by CH1 / P1 and CH2 / P2.
  3. Confirm the facility AC input.
    Determine whether the project uses 120V, 208V, 240V, 277V, 347V or 480V-class electrical distribution.
  4. Select the fixture power direction.
    Use R2 / R2E-V for compact dual-channel applications or R6-V for high-power top-grow lighting.
  5. Confirm independent-channel requirements.
    Determine whether both LED loads need separate dimming or operating behavior.
  6. Define the control method.
    Specify 0–10V, PWM or other supported control requirements.
  7. Determine whether dynamic power allocation is needed.
    For applicable R6-V fixtures, define whether available power must shift between channels during operation.
  8. Specify auxiliary requirements.
    Confirm whether the project requires an auxiliary DC supply, control interface or other configuration options.
  9. Review environmental and thermal conditions.
    Check IP rating, humidity, enclosure construction, connectors, operating temperature and driver cooling.
  10. Confirm target-market certification.
    Final driver selection should include the applicable safety, EMC and finished-luminaire certification requirements.

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

Choose a multi-channel driver when the grow-light fixture contains two separate LED loads that require different electrical operating points or independent control.

If the complete fixture operates as one regulated LED load, a single-channel driver normally provides the simpler architecture. For those projects, compare
