AL800i
Precision lighting intelligence
for animal welfare and performance

A NEW STANDARD IN ANIMAL
AND BIOLOGICAL LIGHTING

Light is one of the most powerful environmental factors in modern livestock, aquaculture and controlled biological systems. It influences behavior, stress levels, feeding patterns, reproduction and long-term health. Yet animal lighting has historically been designed and evaluated using human-based metrics that do not reflect how animals truly perceive their environment. The AL800i spectro – flicker meter was developed to change this.

The AL800i is not simply another spectrometer. It is a dedicated spectro-flicker meter engineered specifically for animal and biological lighting applications. It provides professionals with scientifically reliable insight into both the spectral and temporal behavior of light, enabling the design of environments that support animal welfare, productivity and sustainable performance.

MAKING BIOLOGICAL LIGHT MEASURABLE

Every measurement performed by the AL800i is captured through a high-precision CCD sensor with a wavelength detection range from 300 to 800 nanometers. This bandwidth covers the full visible spectrum as well as the critical near-UV region that many animal species can perceive. This allows lighting systems to be evaluated based on their true biological impact rather than only human perception.

The instrument continuously ensures measurement stability through automatic shutter control and dark calibration. This eliminates drift and environmental variability, which is essential in agricultural and biological environments where lighting conditions change throughout the day. The result is reproducible and reliable data in both laboratory research and real production environments.

ENGINEERED FOR MODERN AND AQUACULTURE

The AL800i is designed for professionals working in poultry, dairy, livestock, fish farming, aquaculture, algae cultivation and advanced biological research. In poultry production, light directly affects growth, feed conversion and egg production. In dairy and cattle farming, optimized lighting can improve reproductive cycles, milk yield and overall herd stability. In aquaculture and algae systems, spectrum and intensity influence growth rates, stress and survival.

The compact and lightweight design makes the instrument easy to use in demanding environments such as barns, hatcheries and controlled cultivation systems. Its intuitive interface presents clear spectral graphs and essential data, supporting fast and confident decision-making in daily operations.

Spectral and temporal insight
in one instrument

Many animals are far more sensitive to flicker and modulation than humans. Light fluctuations that are invisible to the human eye can cause stress, behavioral changes and reduced performance. As a dedicated spectro-flicker meter, the AL800i measures both spectral output and temporal light behavior. This enables professionals to evaluate driver quality, dimming stability and frequency characteristics that directly influence animal welfare.

By combining spectral and flicker analysis in one platform, the AL800i provides a complete understanding of lighting environments and supports the development of stable, welfare-driven lighting strategies.

Data that supports scientific
and operational decisions

Unlike closed ecosystems that restrict access to data, the AL800i provides transparent and flexible reporting. Measurement results can be exported directly to an advanced Excel framework, including spectral graphs, intensity distributions and animal-relevant light parameters. This ensures reproducible analysis and easy collaboration between farms, consultants, researchers and regulatory bodies. 

For automated installations, the instrument also supports MODBUS RS485 communication, enabling integration into smart agricultural systems, research facilities and environmental monitoring platforms.

For professionals who place
animal welfare first

The AL800i is trusted by universities, agricultural technology companies, lighting manufacturers, veterinarians, consultants and progressive farming operations. Its European calibration, durable construction, high-clarity touchscreen and long battery life make it ready for continuous use in both commercial and scientific environments.

professional expectations

Every AL800i includes European calibration, a one-year standard warranty and lifetime firmware updates. For organizations seeking additional security, an extended protection program with full product replacement insurance is available. This ensures continuity and protects operations where lighting performance is critical.

Users benefit from direct access to technical specialists who understand both the technology and its biological applications, ensuring fast and meaningful support.

AL800i, BECAUSE ANIMAL WELFARE BEGINS WITH THE RIGHT LIGHT.

With the AL800i, light becomes measurable, biological impact becomes predictable and performance becomes sustainable. It is the essential tool for professionals who aim to create healthier animals, stable environments and future-ready production systems.

THE POWER OF FREEDOM:
A remotely operated
detachable sensor head.

A BREAKTHROUGH IN OPTICAL MEASUREMENT

One of the most defining innovations within the AL800i ecosystem is the detachable sensor head, a breakthrough that fundamentally reshapes how professionals measure light. Instead of maneuvering an entire handheld instrument into place, users can position the sensor independently and operate it completely from the base platform. This creates a new level of freedom, precision and control that sets the AL800i apart from traditional spectrometers. What may appear as a convenience feature is, in practice, a transformative leap in workflow efficiency, measurement accuracy and user safety.

TRUE STAND ALONE FUNCTIONALITY

The sensor head is engineered as a fully capable stand alone unit. It can operate either wired or wireless depending on the user’s environment and needs. In a wired configuration, the USB C connection provides stable power and continuous data transfer. In wireless mode, Bluetooth communication enables precise measurements from a distance without any physical interaction. Regardless of how it is connected, the sensor maintains the same level of scientific reliability. It can be placed inside luminaires, within multi layer growing systems or directly at canopy height without moving the main device.

WIRELESS CONTROL FROM THE BASE PLATFORM

A defining advantage of the AL800i is that the detachable sensor head remains fully controllable from the base instrument. Users can initiate measurements, adjust settings and monitor real time data remotely. This capability allows readings in locations that are difficult, time consuming or unsafe to access. The AL800i becomes the central command platform, while the sensor acts as a precision satellite collecting data exactly where it matters most.

CONNECTIVITY BUILT FOR PROSESSIONAL ENVIRONMENTS

The detachable sensor head is equipped with a complete suite of modern communication options. Bluetooth supports wireless and mobile operation. USB C provides high speed data transfer and continuous power delivery. MODBUS RS485 makes integration with PLC systems and automated environments effortless. This range of connectivity positions the AL800i perfectly for scientific research, horticultural operations, quality control workflows and industrial monitoring.

OPTIMIZED FOR REAL WORLD MEASUREMENT SCENARIOS

To enhance its practical use, the detachable sensor head can be mounted on the included aluminum tripod for stable, fixed position measurements. For extended reach or overhead applications, the sensor can be positioned on the extended measuring stick with its dedicated bracket. This allows users to capture readings above cultivation tables, deep inside lighting structures or across vertical rack systems with minimal effort.
When long duration measurements are required, the sensor head can be powered directly by the included powerbank, ensuring extended operation during prolonged research sessions, continuous monitoring or fieldwork away from fixed power sources. These accessories transform the sensor head into an adaptable, professional grade measurement tool capable of meeting any environmental challenge, from greenhouse aisles to laboratory setups and elevated lighting structures.

“This isn’t simply
a feature.
It’s the future of light
measurement.“

ACCESSING THE INACCESSIBLE

By separating the sensor from the main instrument, entirely new measurement possibilities emerge. Heights, confined spaces, delicate crop zones or heavily illuminated fixtures can be assessed safely and easily. The sensor goes directly to the light source while the user remains comfortably positioned at the base platform. This approach not only improves measurement accuracy but also significantly enhances safety, ergonomics and workflow efficiency.

A NEW STANDARD IN MEASUREMENT FLEXIBILITY

This modular architecture represents the core design philosophy of OBSIDIAN, which is freedom where it matters and precision where it counts.
