Equipped with a UL-listed brand driver, 6-band full spectrum (3000K + 5000K + 660nm + 730nm + 450nm + 395nm), and WiFi/Bluetooth smart control with daisy-chain capability for 100+ fixtures, the SPL-SP66-1200 is built for growers who demand serious, scalable lighting infrastructure.
Key Features and Benefits
Reliable Power and UL-Listed Safety
The SPL-SP66-1200 is powered by a UL-listed brand driver specifically selected for commercial horticulture environments. UL listing means the driver has passed rigorous independent safety testing for electrical shock, fire, and overload protection, a critical requirement for insurance compliance and facility inspections in North America and many international markets. The driver delivers stable output across a wide voltage range (AC180V to 277V), with power factor greater than or equal to 0.95.
Maximum Efficiency with Extended Lifespan
At 2.9 µmol/J photosynthetic photon efficacy, the SPL-SP66-1200 converts electrical input into usable plant light with industry-leading efficiency. The high-efficiency LED array runs each diode below its maximum rated current, reducing thermal stress and significantly extending fixture lifespan beyond the 50,000-hour rated lifetime. For commercial operations running lights 16 to 18 hours per day, this translates to 8+ years of reliable service.
Precision 6-Band Full Spectrum
The SPL-SP66-1200 uses a carefully engineered 6-band spectrum targeting every photoreceptor plants use: 3000K warm white for flowering response, 5000K cool white for vegetative growth, 660nm deep red for photosynthetic efficiency, 730nm far-red for Emerson enhancement and flowering control, 450nm blue for compact canopy structure and root development, and 395nm violet for phototropism and anthocyanin production. This multi-band approach delivers up to 20 to 40% yield improvement over single-spectrum fixtures.
Versatile Dimming and Smart Control
Fine-tune your grow environment with dual dimming options: a physical VR 0-10V knob on the fixture for quick manual adjustments, and a precision RJ11 port for integration with environmental controllers. The included WiFi/Bluetooth smart controller and mobile app let you manage your entire grow operation from your smartphone. Set automated sunrise/sunset schedules, adjust intensity by zone, monitor power consumption in real time, and receive alerts. The daisy-chain architecture supports 100+ fixtures on a single control network.
Effortless Large-Scale Management
The daisy-chain design is a core engineering feature. Connect 100+ fixtures in a single chain, control them all from one app interface, and eliminate the need for individual fixture programming. This is critical for commercial operations where consistency across hundreds of lights directly impacts crop uniformity and yield predictability. Compatible with most major greenhouse automation systems via the 0-10V protocol.
Full Customization Available

The Science Behind Your Spectrum
Understanding how each wavelength affects plant development helps you optimize your grow environment for maximum results.
395nm Violet Light
Violet light sits at the center of plant phototaxis, the biological mechanism that directs plant growth toward light sources. It plays a critical role in photomorphogenesis, influencing leaf thickness, stem elongation, and overall plant architecture. Violet light also inhibits excessive stem elongation and stimulates anthocyanin production, which enhances fruit coloration and petal vibrancy.
450nm Blue Light
Blue light is essential during the early vegetative stage, promoting strong root system development and compact, sturdy stem growth. Chlorophyll a and chlorophyll b have peak absorption rates in the blue spectrum, driving protein and amino acid synthesis. Proper blue light exposure results in shorter internode spacing and denser canopy structure.
660nm Deep Red Light
Red light is the primary driver of photosynthesis. Under appropriate blue light conditions, photosynthetic efficiency reaches its maximum at 660nm. Red light stimulates carbohydrate production, promoting

660nm Deep Red Light
Red light is the primary driver of photosynthesis. Under appropriate blue light conditions, photosynthetic efficiency reaches its maximum at 660nm. Red light stimulates carbohydrate production, promoting taller plants with larger leaf surfaces for greater light interception.
730nm Far-Red Infrared
Far-red light converts the photoreceptor pigment Pfr into Pr, which influences flowering timing and photoperiod control. When combined with 660nm, the Emerson Enhancement Effect produces photosynthetic rates significantly higher than either wavelength alone.
Frequently Asked Questions
How much area does one 1200W fixture cover?
One SPL-SP66-1200 covers approximately 6 x 4 feet (180 x 120 cm) when mounted at 12 inches from the canopy. At 18 inches, coverage expands but peak intensity decreases, suitable for vegetative growth. At 24 inches, the footprint is widest, but intensity drops significantly, appropriate for seedling propagation. For commercial flowering operations targeting maximum yield, we recommend 12-inch hanging height. Contact our engineers for a free lighting layout customized to your facility.
What is the difference between the 1200W and 1300W models?
The SPL-SP66-1200 (1200W, 3480 umol/s) and SPL-ZP610-1300 (1300W, 3770 umol/s) share the same 6-band spectrum, driver quality, dimming system, and smart control features. The 1300W model produces approximately 8% more PPF and is ideal for light-hungry crops or facilities with higher ambient temperatures where additional photon flux compensates for environmental factors. For most commercial operations, the 1200W delivers excellent results at a lower per-fixture energy cost.

The effect of light quality on plants
395nm violet light
1. Purple light is the central area of plant phototaxis and can affect plant morphogenesis.
2 . Purple light inhibits the growth of the trunk and foliar surfaces of plants (inhibits leggy growth).
3. Purple light can stimulate plant cyan pigments, causing plant fruits/ petals or leaves to color and improve quality.
450nm blue light
1. Blue light has a significant impact on the early stages of plant growth, assisting plants in establishing a well-developed root system.
2 . Blue light inhibits the growth of the plant’s trunk and leaf surface, but increases the sturdiness of the trunk.
3. Chlorophyll a/b has a strong absorption rate in the blue light region and mainly helps plants synthesize proteins and amino acids.
660nm red light
1. Red light is the main force of photosynthesis, and under certain blue light conditions, the efficiency of photosynthesis is at its best.
2. Red light mainly helps plants produce carbohydrates, which makes the plant grow taller and the leaf surface larger.
3. In weak light environments, red light has the highest efficiency in promoting photosynthesis in plants.
730nm infrared light
1. Through infrared light irradiation, the photosensitive pigment Pfr is converted into Pr, thereby inhibiting plant flowering and controlling the flowering cycle:
2. Combined with 660nm, dual-light gain benefits can be achieved, which is much higher than the photosynthesis efficiency of 660nm alone
