As a trader or seller, it’s crucial you can confidently guide customers to quality, proven products for their needs and budget. This detailed guide will arm you with the knowledge to compare different red light therapy systems and recommend the ideal solutions for your client’s goals.

Key Factors To Consider

There are several key factors that determine the quality and potential benefits of a red light therapy device:

LED light wavelengths to body


The wavelengths in the visible red (660nm) and near-infrared (850nm) spectrum have been clinically shown to deliver optimal therapeutic results, according to Mayo Clinic. Some devices also incorporate other wavelengths like blues or greens, but red and NIR are the most critical.

Power Density

This measures the power or intensity of the LED light and is expressed in milliwatts per square centimeter (mW/cm2). Most research suggests power densities between 30-80 mW/cm2 provide ideal dosages, per Cleveland Clinic. Higher-density panels above 100 mW/cm2 need shorter treatment times. Avoid ultra-low-density devices.

Treatment Surface Area

Larger treatment areas allow more of the body to be exposed at once for faster sessions. Look for panel sizes from 12”x12” up to 48”x24” or more. Spot treatment lasers cover the least area.

LED Quality

Medical-grade LED diodes tested for spectral purity and tight wavelength tolerances should be used. Cheap low-quality LEDs tend to have broader spectrums with less therapeutic value.

Ease of Use

Devices should have adjustable heights, flexible heads, and user-friendly designs for positioning the light conveniently over any body part. Wall-mounted units offer the most versatility.

FDA, CE, Rohs 70+ Certifications

Safety Certifications

Legitimate devices are certified by organizations like the FDA, CE, and FCC to meet product safety standards. Beware of non-certified devices, especially when LEDs are close to the eyes.

Now let’s compare some of the most popular red light therapy systems available based on these criteria.


Clinical Red Light Therapy Panels

These full-sized panels designed for medical and professional use offer the highest treatment power and performance. Key features:

Power Density – Up to 200 mW/cm2 (or more) for fast results

LED Quality – Top-tier medical grade LEDs for purity and precision

Wavelengths – Research-backed red/NIR wavelengths between 630-880nm

Treatment Area – Large panels up to 48”x24” to cover more skin

Adjustability – Flexible stands and arms allow easy repositioning

Reliability – Proven quality from brands like Joovv, Red Light Man, Platinum LED Therapy

Safety – Tested to medical device standards

Clinical panels deliver optimal dosages thanks to higher intensities and large treatment areas. While expensive at $995 to $5,995, they provide robust results per study. Suitable for both clinics and home use.

“The power density, wavelength range, and quality of LED diodes make these clinical devices the gold standard for results.”

Red Light Therapy Masks

Face masks are an affordable option for convenient at-home treatments. Here are key features:

Price – As little as $150-$300 for an entry-level mask

LEDs – contain arrays of visible red and sometimes near-infrared LEDs

Coverage – Treat only the facial area, not the body

Dosage – Tend to be lower densities around 30-100mW/cm2

Convenience – Hands-free, wearable design

Limitations – Lower power, smaller treatment areas

A quality mask like those from CurrentBody, Infraredi, or Joovv provides solid value for targeting facial skin, acne, and wrinkles when used consistently. Masks won’t treat pain, injuries, or body areas.

“Masks increase collagen, improve facial circulation, and rejuvenate skin with regular use,” says Dr. Terry Dubrow.

Red Light Therapy Wands

These handheld wands enable targeted light treatment for small areas of pain, wounds, and skin issues:

Spot Treatment – Pinpoint red/NIR light to specific body parts like knees, shoulders, backs, faces, etc.

Portability – Compact size under 12” long for easy handling

Weight – Ultra lightweight, only a few ounces

Power Density – Up to 250mW/cm2 for deeper penetration

Cost – Affordable around $100-$250

Versatility – Treat anywhere on the body with precision

Wands work well for joint pain, skin imperfections, and recovery per doctors. The limitation is the small coverage area compared to panels.

“Handheld wands are powerful convenient tools that allow focused spot application of therapeutic light,” says Dr. Anisha Joshi.

Large Infrared Heating Panels

Some far infrared sauna companies now offer large LED panels to mount inside saunas for amplification of benefits:

Combination Therapy – Merges the power of heat and light

Spectrum – Quality LEDs offer both red and NIR wavelengths

Coverage – Large panels mounted on back walls or ceiling

Intensity – Up to 130mW/cm2 for optimal dosing

Heat Tolerance – Designed for prolonged heat exposure

Cost – Around $600-$1500 depending on sauna size

Limitation – Requires investment in infrared sauna unit

Infrared heating panels are powerful additions but require sauna ownership first. Together, the therapies boost circulation, detoxification, and cellular effects based on research.

“The synergy of simultaneous infrared and red light exposure propels health improvements faster.”

Veterinary Red Light Pads

Red light pads designed specifically to treat pet pain, wounds, joint issues, and skin conditions:

Vet Recommended – Products validated for safety/results in dogs, cats, horses

Low Height – Adjust down to floor level for pets

Treatment Zone – Large enough for full pets (50x50cm for example)

Preset Programs – Sessions optimized for specific animal types

Dosage – Appropriate power density and duration for pets

Cost – $500-$1500

Limitation – Intended for animal use only

Legitimate veterinary red light pads have clinical studies proving efficacy and safety for pets. They provide pet owners with a holistic treatment alternative according to vets like Dr. Ziegel.

Personal Red Light Therapy Devices

Miniature red light therapy panels designed for consumers provide lower-cost options for spot treatment:

Compact Size – Small units like 12″x12” stand

Price – $200 to $500 range

Convenience – Use on tabletops or floors

Spot Treatment – Target specific problem areas

Portability – Fully self-contained and lightweight

Power Density – On the lower side around 30-50mW/cm2

Limitations – Narrow wavelength range, low intensity, small surface area

While affordable and easy to use, limitations like lower intensity LEDs and coverage may hinder results. Best for minor issues, not chronic pain or anti-aging.

“These devices offer an introduction to red light therapy, but won’t match the power of professional clinical systems.”

Red Light Laser Devices

Handheld red laser units allow concentrated treatment in a tight beam. Key traits:
