MIGRO ARAY 1 LED Grow Light

The Migro ARAY 1 is a compact but powerful 55-watt full-spectrum LED grow light, designed for optimal sowing and growing conditions. With an efficiency of 2.7 µmol/J, the ARAY 1 delivers maximum usable light per watt and keeps heat generation and energy consumption low. The compact bar covers a growing area of approximately 0.6 × 0.4 m and is ideal for up to 12 seedlings. The high-quality LED mix combines Samsung LM281B white chips (4000K, 95 CRI) with Osram red LEDs, for a balanced spectrum that stimulates vegetative growth and terpene/flavonoid production. The dimmable driver allows easy adjustment to each growth stage. With a lifespan of 50,000 hours and a 3-year warranty, the ARAY 1 is reliable and future-proof.

Power 55 watts

Migro ARAY 1 has a nominal power of 55 watts, which provides powerful yet energy-efficient light output suitable for compact grow rooms. This power provides sufficient intensity to effectively illuminate a growing area of approximately 0.6 × 0.4 m without excessive heat generation. The 55w driver is dimmable, making the Migro ARAY 1 flexible for use during sowing, vegetative, and early flowering phases and easy to integrate into larger installations.

Efficiency 2.7 µmol/J

The Migro ARAY 1 delivers an efficiency of 2.7 µmol/J, which means that every watt of electrical power results in 2.7 micromoles of usable photosynthetic photons per second. This efficiency reflects the usable PPF and optimizes light utilization at low energy consumption, which both reduces operating costs and limits heat emission. For hobby and professional growers, the ARAY 1 therefore offers an excellent balance between energy consumption and crop productivity.

LED brands and quality

The LED mix in the Migro ARAY 1 combines high-quality Samsung LM281B+ pro Pure white 95CRI 4000K CT, chosen for color stability, lumen maintenance, and spectral precision. Samsung LM281B is known for high efficiency and good color rendering, while Osram red chips provide extra far red/red output for photosynthesis optimization. This component choice improves consistency, light distribution, and service life to approximately 50,000 hours.

Pure white 95CRI 4000K CT Spectrum

The full spectrum of the Migro ARAY 1, centered around 4000K with the addition of red LED emissions, is tailored to both vegetative growth and the development of terpenes and flavonoids during flowering. The broad spectrum combines temporarily neutral white light with targeted red peaks to stimulate leaf growth, photosynthetic efficiency, and secondary metabolite formation. This results in natural color rendering and balanced light quality for different growth stages.

Smart control and dimmer

Migro ARAY 1 is equipped with a dimmable driver and designed for easy integration with external controls: timers, dimmers, and many common smart controllers. The dimming function allows fine adjustment of light intensity per growth stage, while integration options support automatic day/night schedules and power tapers. This allows Migro ARAY 1 to work seamlessly with existing cultivation automation for optimal workflow and energy management.
