The SOLUX LAB

Welcome to The SOLUX LAB. This is the technical companion to our red light therapy guide: a place to understand device specifications, measurements and research. Solux is a UK red light therapy specialist. Solux products have been measured against their specifications; this page explains what those measurements mean without inventing model-by-model figures or claiming that a safety mark proves clinical effectiveness.

What is photobiomodulation?

Photobiomodulation (PBM) is the research term for biological responses to selected light exposures. Studies use LEDs or other light sources and specify parameters such as wavelength, output, exposure time and treatment area. A finding from one device or protocol cannot automatically be applied to another. PBM research is not, by itself, proof of a particular consumer product’s efficacy.

Wavelengths explained

Wavelength is measured in nanometres (nm). Visible red wavelengths, including 630 nm and 660 nm, differ from near-infrared (NIR) wavelengths such as 810 nm, 830 nm and 850 nm. NIR is generally invisible to the eye. A wavelength alone does not establish delivered dose or outcome. Check the exact wavelengths listed for each product rather than assuming all models use the same LEDs.

Irradiance explained

Irradiance describes optical power reaching a unit of area, commonly expressed in milliwatts per square centimetre (mW/cm²). The result depends on distance, angle, position and measurement method. Electrical wattage is not the same as irradiance at the treatment surface. For a useful comparison, look for the measurement distance, operating mode and whether a reading represents a single point or an average across an area.

Fluence explained

Fluence, or energy density, is energy delivered per unit area during an exposure, usually in joules per square centimetre (J/cm²). In a simplified constant-output example, 10 mW/cm² for 100 seconds equals 1 J/cm². Real use is more complicated if distance, angle or output changes. This explains a unit, not a recommended treatment dose; more exposure is not necessarily better.

How we test our devices

Solux products have been measured against their stated specifications. The most useful way to present a device check is by exact model and version, the characteristic measured, test setup, distance and operating mode where relevant, and the result in its proper units. We distinguish measurements against specifications from independent clinical testing. Specific instruments, test dates, personnel, calibration methods and external laboratory status are not stated here because those details have not been supplied for this page.

Solux wavelength measurements

Solux devices have been measured against their stated wavelength specifications. These checks concern the wavelengths emitted by the particular model, not a blanket claim that every device includes every red and NIR wavelength. For a meaningful model-specific wavelength record, look for the measured spectrum, operating mode, instrument and any stated tolerance. Individual numerical readings are not reproduced on this page; refer to the relevant product’s stated wavelengths and request its measurement record from Solux if needed.

Solux irradiance measurements

Solux devices have been measured against their stated specifications, including irradiance specifications where applicable. Irradiance must be understood alongside the distance and position at which it was measured, as well as the light mode and unit. A reading at one point is not necessarily the average across a treatment area. This page does not quote numerical irradiance values without their model-specific test conditions; check the individual product information or ask Solux for the corresponding record.

EMF measurements

EMF stands for electromagnetic fields. An interpretable EMF result needs the exact device, operating mode, instrument, units, measurement position and distance. A reading at one position does not describe every use condition. Solux’s statement that products have been measured against specification should not be read as a particular EMF value or a “zero EMF” claim; model-specific readings and conditions should accompany any numerical claim.

Flicker testing

Some light sources vary in output over time, even when that variation is not obvious to the eye. A useful flicker test identifies the device and mode, measurement method, frequency and modulation. A phone video is not a definitive test. Measurement against a product specification should not be confused with a universal “flicker-free” claim; any such claim needs the model-specific test result and conditions.

Safety & certification

For UK shoppers, look for applicable conformity markings, relevant documentation, electrical safety information, clear operating instructions and manufacturer or importer details for the exact model. UKCA or CE marking may be relevant depending on the product and applicable rules. A conformity mark is not evidence of clinical efficacy or approval to treat a medical condition. Follow the device’s eye protection, distance and session guidance; seek professional advice before use if you have a medical concern or photosensitivity.

Product testing reports

Measurements against specifications are most useful when traceable to the exact product model. A report should identify the model and version, test method, date, measurement setup, results and responsible organisation. Solux can provide the relevant model-specific records where available; reports are not attached to this page, so we do not imply that a downloadable independent laboratory library is currently published here.

Research library

Research about photobiomodulation should be distinguished from product-specific measurement records. A useful research entry identifies authors, publication, year, participants, light source, wavelength, dose, outcomes and limitations, with a link to the original publication. We will not invent citations or imply that a general PBM paper tested Solux equipment. Use the checklist below when assessing research or marketing claims.

Clinical research explained

When reading a study, ask whether it was conducted in people or in a laboratory, how many participants were involved, whether there was a comparison group, and what outcome was measured. Then compare wavelength, irradiance, fluence, treatment distance and session schedule with the device and use you are considering. Check whether harms and conflicts of interest were reported. A positive finding for one narrow outcome does not guarantee the same result from every device or for every person.

Our evidence standard: Solux measurements against product specifications, independent product testing and clinical evidence are different kinds of information. We aim to keep them separate. This page is educational and not medical advice, diagnosis or treatment. Refer to your device manual for product-specific use.
