Targeted panels through to full-body systems, compared on the specifications that actually differ between brands.

Not yet open for online ordering

Red Light Therapy is not open for online ordering yet.

Equipment is listed only once its specifications, warranty terms, and service arrangements have been verified — so this page shows nothing rather than something we cannot stand behind. The buying guidance below covers what to compare. An advisor can tell you what is available today, source a specific system for a project, or record what you are looking for and tell you when it opens.

Ask an advisor about Red Light Therapy

Red light is the category where the gap between marketing and measurable specification is widest. Panels are commonly sold on total wattage and LED count — two figures that tell you almost nothing about what reaches your skin.

What determines whether a panel does anything is the dose delivered: the wavelengths emitted, the irradiance at the distance you actually stand, and the time you spend there. A manufacturer that publishes those three figures, with the measurement distance stated, is giving you something comparable. One that leads with "3,000 watts" and an LED count is not.

Why buyers consider Red Light Therapy

  • Sessions are short, require no water, no heat, and no plumbing, and produce no mess — which makes this the easiest recovery technology to fit into an existing routine.
  • Panels scale from a small targeted unit for one joint up to full-body arrays, so the entry point can be modest.
  • No consumables and very little maintenance, so ownership cost after purchase is largely electricity.
  • It is quiet and can be used while doing something else, which is why adherence tends to be higher than for more demanding modalities.

What to compare before buying

Wavelengths
Most devices emit in the red band (commonly around 630–670 nm) and the near-infrared band (commonly around 810–850 nm). Red is absorbed more superficially; near-infrared penetrates further. A panel offering both, with the specific nanometre figures published rather than a vague "red and NIR", is giving you a specification you can compare against the research.
Irradiance, and the distance it was measured at
Irradiance is power per unit area, usually quoted in mW/cm². It is meaningless without the measurement distance, because it falls off sharply as you move away from the panel. A figure quoted at 3 inches and a figure quoted at 18 inches describe completely different devices. Always ask for irradiance at the distance you would realistically use.
Total wattage and LED count
These describe what the panel draws and how many diodes it contains, not what reaches you. A high wattage panel with poor optics and wide beam angles can deliver less usable irradiance than a lower-wattage panel with better engineering. Treat both figures as marketing rather than specification.
Coverage area
Decides whether you treat one area at a time or your whole body in a single session, which in turn decides session length and whether you will keep doing it. A targeted panel used on four areas in sequence is four sessions.
Panel versus bed
Panels are cheaper, more flexible, and need wall or stand space. Beds deliver whole-body coverage in one session with consistent distance, at significantly greater cost and footprint, and are the usual choice where throughput matters. For most households a panel is the right answer.
Third-party measurement
Some manufacturers publish independent measurement of spectral output and irradiance. That is a meaningful differentiator in a category where self-reported figures are frequently optimistic.

The specifications that actually matter

Dose
Dose is irradiance multiplied by time, usually expressed in J/cm². It is the figure the research is actually built on, and the reason more is not automatically better: the literature describes a biphasic response, where output beyond a certain point can produce less effect rather than more. A manufacturer who can tell you the dose delivered in a stated session at a stated distance understands their own product.
Treatment distance
The variable most owners get wrong. Standing closer is not automatically better, and the manufacturer should specify a distance rather than leaving you to guess.
Beam angle
Narrower beam angles concentrate output and hold irradiance better with distance; wider angles spread it. Rarely published, and worth asking about.
Thermal management
High-output panels generate heat. Fans keep the diodes within their operating range and protect their life, but they make noise. Ask about both the cooling approach and the noise level.
Electrical requirement
Most residential panels run on a standard household circuit. Large full-body arrays and beds may not — confirm before purchase.
Eye safety guidance
High-output devices should come with clear manufacturer guidance on eye exposure and eyewear. Follow the guidance supplied with the specific device; a manufacturer who provides none has told you something about the product.

Space and installation

  • Decide mounting first: wall-mounted, door-hung, on a stand, or on a horizontal rack. This determines whether the panel gets used or gets leaned against a wall and forgotten.
  • Allow the manufacturer-specified treatment distance as clear floor space in front of the panel — this is usually the real space requirement, not the panel footprint.
  • For full-body coverage standing up, check ceiling height and panel height together.
  • Beds need the footprint of the bed plus clear access on at least one long side.
  • Panels are usually mains-powered from a standard outlet; plan cable routing so it is not a trip hazard across the treatment area.

Electrical, ventilation, drainage, and structural requirements

  • Electrical. Most panels use a standard household circuit. Confirm the requirement for large arrays and beds, and have a licensed electrician verify anything that calls for a dedicated circuit.
  • Structural. Wall-mounted panels can be heavy. Fix into structural framing rather than plasterboard alone, and use the manufacturer bracket.
  • Ventilation. No air-handling requirement, but panels with active cooling need clear airflow around their vents and should not be enclosed.
  • Drainage. None required.
  • Heat. A high-output panel warms a small room noticeably over a session. Worth knowing if the room is already warm.

Maintenance and sanitation

  • Wipe the lens or diode face periodically. Dust reduces output, and it is the most common cause of a panel quietly underperforming.
  • Keep cooling vents and fan intakes clear.
  • Check the manufacturer stated LED service life and what happens at end of life — most diodes dim gradually rather than failing outright, so output declines invisibly.
  • Confirm whether individual diodes or modules can be replaced, or whether a failure means replacing the panel.
  • No consumables, no filters, no water chemistry. This is the lowest-maintenance category in the range.

Residential versus commercial use

Residential panels are built for a few short sessions a day. In a studio, gym, or spa the same panel may run continuously, which stresses the diodes, the drivers, and the cooling system, and output declines faster under that load. Commercial installations also need surfaces that can be cleaned between clients, protective eyewear provision, clear session protocols, and often a fixed mounting arrangement rather than a stand. Beds are usually the commercial answer because they standardise distance and cut session time. Specify for the duty cycle from the start — see IMPERVITA PRO.

Warranty and service questions to ask

  • How long are the LEDs covered, and is there a stated output-degradation threshold that counts as a failure?
  • Are drivers and power supplies covered on the same terms as the diodes? They frequently fail first.
  • Is the warranty void if the panel is used commercially?
  • Are replacement modules and drivers stocked, and for how long after the model is discontinued?
  • Does the manufacturer publish independently measured irradiance, and will they stand behind that figure?
  • Who pays return freight on a large panel or bed?
  • Is the mounting hardware covered, and is professional installation required for wall mounting?

What the evidence shows

Photobiomodulation has a substantial mechanistic literature centred on the absorption of red and near-infrared light by cytochrome c oxidase in the mitochondria, and reviews have examined its anti-inflammatory effects and its application to muscle tissue in the context of exercise and recovery. A systematic review has specifically assessed the oncologic safety of low-level light therapy used for skin rejuvenation. The literature consistently describes a biphasic dose response, which is the single most practical finding for a buyer: the correct dose matters more than the largest panel.

What the evidence does not establish

Much of the supporting work is mechanistic, preclinical, or conducted in cell and animal models, and demonstrating a plausible cellular mechanism is not the same as demonstrating a clinical result in a person. Human trials are generally small and highly heterogeneous, and reviews repeatedly note that wavelength, irradiance, and total dose are inconsistently reported — which makes studies hard to compare and hard to reproduce. Many studies used clinical laser devices or research-grade equipment rather than consumer LED panels, so the parameters do not transfer directly. Optimal dosing is not established for any application. None of this establishes that red light therapy treats, cures, prevents, or mitigates any disease, and claims of that kind should be treated as unsupported. Anyone with a photosensitising condition, taking photosensitising medication, with a history of skin cancer, or who is pregnant should speak to a physician before use, and manufacturer eye-safety guidance should be followed exactly.

Buyer checklist

  • Specific wavelengths in nanometres obtained, not "red and near-infrared".
  • Irradiance obtained at a realistic treatment distance, with that distance stated.
  • Dose per session at that distance calculated or supplied.
  • Independent measurement asked for.
  • Coverage area matched to how much of the body you intend to treat.
  • Mounting method decided and structural fixing confirmed.
  • Clear floor space at the treatment distance measured.
  • Cooling noise level checked.
  • Manufacturer eye-safety guidance read.
  • Driver and LED warranty terms compared separately.

Ask an advisor for irradiance at your intended treatment distance and the resulting session dose. Any panel worth buying comes with those numbers.
