R2-2 Dual-Channel Under-Canopy Grow Light LED Driver
Ultra-narrow non-isolated dual-channel LED driver for under-canopy and inter-lighting grow fixtures, with independent channel dimming, programmable current, 0–10V / PWM control and 120–277Vac or 277–480Vac input platforms.
Ultra-Narrow Dual-Channel Driver for Under-Canopy & Inter-Lighting
The FAHOLD R2-2 Series is an ultra-narrow dual-channel non-isolated constant-current LED driver platform developed specifically for space-constrained LED inter-lighting and under-canopy supplemental grow-light fixtures. The family covers 150W, 240W and 300W power classes, with 120–277Vac rated input for R2 models and 277–480Vac rated input for R2E-V models.
Both output channels support independent dimming, allowing horticulture fixture designers to control separate LED loads within the same under-canopy or inter-lighting platform. The series supports programmable output current, 0(1)–10V and PWM control, optional dynamic aux-to-main power transfer, optional 12V / 250mA auxiliary power, DM 8kV / CM 8kV surge protection, SCP / OCP / OTP protection, and IP42 construction with IP67 available as an option.

Under-Canopy Dual-Channel LED Driver Features
Independent Dual-Channel Dimming
Two constant-current output channels can be controlled independently for separate LED loads in under-canopy and inter-lighting fixtures.
Programmable Channel Current
Adjustable output programming supports fixture-specific current configuration across different horticulture LED loads.
0(1)–10V / PWM Control
Two-in-one control supports 0(1)–10V and PWM dimming for horticulture lighting and supplemental grow-light applications.
Optional Dynamic Power Transfer
Optional aux-to-main power shifting enables dynamic power allocation between the two channels as fixture requirements change.
DM 8kV / CM 8kV Surge Protection
Differential-mode and common-mode 8kV surge protection supports reliable operation in commercial grow-light installations.
IP42 / Optional IP67 Protection
SCP, OCP and OTP functions support electrical protection, with IP42 as the standard platform and IP67 available for compatible configurations.
Under-Canopy & Inter-Lighting Grow Applications
R2-2 Series models are designed for under-canopy supplemental lighting and inter-lighting fixtures where ultra-narrow driver width, dual-channel control and compact integration are critical.
