QUALITY ANALYSIS
Light quality: synchronise your biology
Discover how biologically correct lighting improves your sleep,
mood and vital health.
BIOLOGICAL RHYTHM
How light affects your internal clock
Light is the main synchroniser of our body’s internal clock.
Incorrect exposure can disrupt the production of vital hormones.
Cortisol (Energy)
Activation in the morning requires bright, blue-enriched light.
Melatonine (Sleep)
Requires darkness or dim amber light at night to
induce restful sleep.
The truth about blue light
Not all blue light is bad. During the day, it is essential for keeping us alert. However, exposure to screens and cool LED lights at night suppresses melatonin activation and causes digital eye strain.
Insomnia and fragmented sleep
Headaches and eye fatigue
Controllable with filters and schedules
Adaptable through smart technology.
THE BIOWELLNESS METHOD
Our process of measurement
1· SPECTRAL MEASUREMENT
We use high-precision spectrometers to analyse the composition of light in each room, detecting peaks of harmful blue light.
3· OPTIMIZATION PLAN
We provide a detailed report containing recommendations regarding special light bulbs (biolight), lighting placement and healthy habits.
2· FLICKER ANALYSIS
We detect imperceptible flickering in your current light sources, which is a common cause of migraines and visual stress.
HOW DO WE MEASURE?
Our science-based process for diagnosing the health of your space.
The OHSP-350 spectral colour illuminometer integrates a range of measurement parameters, including spectrum, colour temperature, colour rendering index, illuminance and radiation. Its large 5-inch screen displays each measurement parameter and curve in real time, making it quick and easy to use.
It can measure both broad and narrow spectrum light sources, including LEDs, CFL energy-saving lamps, and high and low pressure HID sodium lamps.
Features of the ZPad flicker meter:
· 4.3-inch touchscreen with direct access to the most important functions.
· High measurement accuracy thanks to the 16-bit analogue-to-digital converter.
· Sampling frequency of up to 1.6 MHz and up to eight measurement channels.
· An optical sensor with spectral sensitivity according to V(λ).
· Flicker evaluation procedures such as PstLM, SVM, Flicker%, Flicker Index or IEEE 1789.
· Additional sensors for measuring infrared (IR), ultraviolet (UV) and electromagnetic fields (EMF). Automatic sensor recognition.
· Measurement signals can be displayed in oscilloscope form or as a frequency spectrum.
BioLight™ Full Spectrum Mode
From a wellness perspective, BioLight™’s ‘Full Spectrum Mode’ is healthier for the optic nerve system because its light spectrum closely mimics natural sunlight.
Spectral similarity: Unlike conventional fluorescent or LED lights, which have pronounced peaks and troughs in their spectrum, BioLight’s Full Spectrum Mode provides a more uniform and complete intensity distribution across the visible range.
· Reduced visual stress: Exposure to a more natural light spectrum can help to reduce eye strain and stress on the optical system because the human eye has evolved to function under sunlight.
· Circadian regulation: A balanced light spectrum is crucial for maintaining healthy circadian rhythms, which regulate sleep and other bodily functions and contribute to overall wellbeing.
· Colour perception: A full spectrum enables more accurate and natural colour perception, which is beneficial for various visual tasks and psychological well-being.
What is lighting comfort, and how does it affect our health?
Lighting comfort refers to the balance of light quantity, quality and distribution in a space. Adequate lighting is essential for regulating our circadian rhythm — the internal clock that controls our sleep, hunger and energy levels.
How does artificial light affect our rest at night?
Exposure to white or blue light (from screens and conventional LED lighting) at nighttime inhibits the production of melatonin, the hormone that regulates sleep. This tricks the brain into thinking it is daytime, making it difficult to fall asleep and reducing the quality of sleep.
What is light flicker, and why is it harmful?
Flicker is an invisible modulation in the intensity of many low-quality LED bulbs. Although we do not consciously see it, our nervous systems detect it, which can cause eye strain, dizziness, irritability, and persistent headaches.
Why is it important to measure colour temperature (Kelvin)?
Colour temperature defines the ‘mood’ of a space. Cool lights (above 5000K) stimulate the body and are suitable for morning work, while warm lights (below 2700K) prepare the body for rest at dusk. A mismatch between these temperatures can disrupt our biochemistry.
Is it enough to simply have a lot of light in a room?
No — a lack of light can be just as harmful as excessive glare or extreme contrasts. Good lighting design seeks uniformity and the highest possible colour rendering index (CRI), enabling the eye to work effortlessly and perceive colours naturally.
What solutions does BioWellness offer to improve lighting?
We carry out technical measurements of lux, colour temperature and flicker levels. Based on these results, we design a biodynamic lighting strategy that mimics the solar cycle. This involves recommending filters, specific luminaires, and a light distribution that promotes productivity and well-being.
