Red Light Therapy Bulbs & Alternatives: A Buyer’s Guide

Contrary to popular belief, bulbs for red light therapy may not be the most effective red light therapy option out there for you.

It definitely has its uses but one bulb may not provide the coverage one would need for therapy sessions at home.

There’s a saying- “It’s better to own a motorbike that may cost a lot but will go the distance than to own a bicycle at 1/10th the cost that may or may not go the distance”

Again we are not saying that RLT bulbs don’t work. It’s simply a matter of ‘what you want vs what you need’

So read along to see the many variants of red light therapy devices, different therapeutic bulbs, applications, variants, and FAQs

Red Light Therapy: What It Really Is?

Red Light therapy treatment uses the therapeutic properties of red and infrared light. Each radiation is used at specific wavelengths and frequencies for their respective positive effects on health. 

The red light therapy bulb and other variants of red light therapy devices start projecting a wavelength of 650nm (RLT). Infrared has a wavelength between 780 nm to 1 nm.

The purpose of the ‘crimson photonic therapy’ is to speed up the healing process by stimulating the pain and speed up the healing effect on the recipient’s system.

LED therapy is turning out to be quite the wellness trend and rightfully so, as these are non-invasive, quick, and need no recovery time from the procedure.

Red Light Therapy provides for enhanced blood circulation into the treated area. They create a mild and relaxing warmth and also flush out toxins from the treated area promptly.

Research on Red Light Therapy 

A group of researchers discovered that the intense light from red light-emitting diodes was beneficial for plants. It aided in plant cell development and growth. 


The discovery mentioned above made the scientists utilize Red Light Therapy for plantations in space in the mid-nineties.

The efficacy of red light in medicine was next-in-line to be investigated. The goal was to determine if red light therapy can boost energy within humans. 

Later, studies suggested that red light therapy is a successful therapy for many reasons. The top ones include muscular atrophy, faster recovery, and bone mass problems caused by low gravity during space exploration.

Red Light Therapy Variants

Solas Red Light Therapy Device Variants

Red Light Therapy Face Mask

LED light therapy masks emit different wavelengths of light to address various skin issues. 

Amber light, for example, aids in the stimulation of collagen and the firming of elastin in the skin. 

Inflammation is reduced and blood circulation is improved when red light is used, which in turn boosts the cell’s energy, improving one’s derma condition.

The masks come in a variety of light therapy, starting from red and not limited to blue. The effect of the red is the same as any other red light therapy machine.

Red Light Therapy Portable Device

Wherever you travel, your cells require recharging. So, when you’re on the go, bring the most powerful, portable red light gadget you can find.

The ‘Solas Mini Portable‘ combines the red and near-infrared light spectrums into a single device and works great on your skin.

Red Light Therapy Sauna

Red light therapy has been found to speed up recovery by promoting healing and reducing inflammation and relieving painful sensations. So when you make a room’s area worth of red light therapy setup, you get a red light therapy sauna.

Sauna sessions can help you get the heart-racing, blood-circulating endorphin surge you want while also potentially sweating away impurities.

Red Light Therapy Bed

Red light beds, which may be seen in salons & wellness clinics, are believed to aid in the reduction of cosmetic skin problems such as age contributed spots and creases.

In a medical office environment, red light therapy could be used to promote healing, repairing tissue, and many more benefits.

Other Forms of Light Therapy Bulbs

LED Light Bulb Variants

Many bright light therapies can control melatonin and other hormones. These are affected by circadian rhythms.

These photo therapies aim to uplift the mood of people who are suffering from the winter blues or even a minor case of seasonal sorrow.

Light therapy may provoke bouts of mania. Therefore, it is also advised that people with bipolar disorder should only use it under the supervision of a specialist or a professional.

1.Infrared Light Bulb

Infrared therapy is a brand-new, cutting-edge light-based treatment. It is used for pain and swelling in many parts of the body.

Infrared light promotes cell renewal, unlike Ultraviolet radiation, which may harm the skin.

2. Dawn Simulators

They imitate the setting of a sunrise. These dawn simulators come in two variants:

  • Those which mimic sigmoidal-shaped dawn that lasts for anywhere from 30 minutes to 2 hours
  • Those that replicate a spring and summer dawn

Typically, you’d sleep through the morning and wake up after sunrise.

Dawn simulators work like computer networks that connect to your tabletop light.

3. Light Boxes

Lightboxes are the typical light setup for people who suffer from seasonally affected depression (SAD). They’re flat displays that emit full-spectrum fluorescent bulbs at a brightness of 10,000 lux or more. A lightbox is generally used for 30 to 60 minutes each day.

4. Blue Light Therapy Bulb

Blue wave technology, or blue light, which is a gentle form of light therapy, proven to be superior to other types/wavelengths of light when it comes to treating specific skin conditions like rosacea, lowering melatonin levels, and controlling circadian responses.

5. UV Light Therapy Bulb

UV Bulbs are great for a range of conditions like improving bacteria-based skin conditions, clearing up acne and more.

The wavelength of UVA is the highest between the UV bands. It can pass through glass windows and enter deep into the skin.

UVA therapies must be used in conjunction with Psoralen, which increases the skin’s receptivity to UV radiation.

The wavelength of UVB is lower. It can only penetrate through the top layer of the epidermis and does not need Psoralen. Plus is usually the go-to band for UV Therapy.

Decide The Proper Dose of Red Light Therapy

RLT Dosing

So, before we figure out what frequency is right for you, let’s go through the principles of red light treatment.

More isn’t always better when it comes to therapy. Going overboard with therapies will reduce their efficacy, so use this guide to figure out what’s best for you. 

Let’s take a look at some crucial factors to consider when determining your optimal exposure with this guide:

  1. A sufficiently strong light (“power output”)
  2. A light capable of treating a vast area (“coverage”)
  3. A grasp of how to use this guide to find the best dose (“frequency of use”)

For The Skin

Distance: 12 inches/ 1 foot
Duration: anything from 1-4 minutes.

Distance: 18 inches/ 1.5 feet
Duration: anything from 1.5-5 minutes

Distance: 24 inches/ 2 feet
Duration: anything from 2-8 minutes

For Deeper Problems

(i.e- muscles, tendons, ligaments, bones, glands, the brain, organs, and so on)

Distance: 6-12 inches/ 0.5-1 feet

Please Note: The deeper the tissue you’re seeking to treat, the closer the light should be to your body. (i.e., 6″)

For The Brain

Distance: 6 inches/ 0.5 feet
Duration: anything from 2-7 minutes/region


Distance: 12 inches/ 1 foot
Duration: anything from 5-10 minutes 5-10 minutes/region

The idea here is to recognize that the distance between you and the light has a significant impact on the dosage your cells get

Who Can Get the Most Out of Red Light Therapy Bulbs?


The use of red or near-infrared light to stimulate, repair, and regenerate damaged tissue is known as photobiomodulation.

Athletes’ sports performance can be improved by both pre-conditioning (light supplied to muscles before activity) and PBM administered after exercise. Red light therapy stimulates tissue repair by boosting blood circulation, amongst other things.

Fundamentally, these devices assist the mitochondria, resulting in decreased strain in the muscles. The development of healthy muscular tissue is aided by increasing the mitochondrial respiration cycle.

As a result, athletes who utilize red light treatment on their muscles can benefit from long-term healthy muscular tissue.

People with Hair Loss

Photons are irradiated into scalp tissues during low-level laser therapy, commonly known as red light therapy or cold laser therapy.

Weak cells absorb these photons, which promote hair growth.

The treatment is usually regarded as being safer, more pleasant, and less intrusive than hair transplants.

Accident Survivors

Inflammatory and swollen are frequent after accidents and procedures, and they cause discomfort, limit mobility, and delay the recovery process.

In several studies, red light therapy has been found to decrease acute or chronic inflammation.

Studies on red light therapy and pain relief have also revealed that cells exposed to natural light create new blood vessels, fibroblasts, and tissue creation, all of which contribute to faster, healthier recovery with less discomfort for patients.

Red light therapy has a proven track record of speeding the wound healing process, injuries, and scars, as well as assisting patients in recovering after surgery with less pain and swelling.

Efficacy of Red Light Therapy Bulbs vs. Panels

Solas thinks that everyone must push their bodies to their limits to be healthy. Solas has designed a high-powered unit with a gorgeous design that allows your internal systems to function at their finest.


Solas RLT Bulb

Red light therapy LED bulbs can deliver particular wavelengths in the therapeutic ranges of 630nm to 660nm (red light) and 810nm to 850nm (blue light) (NIR light).

Compact Bulbs

Because LED red light therapy bulbs are tiny, more of them may be clustered together in a narrow area for optimal coverage and intensity of the light therapy session; the more bulbs there are, the more light energy is absorbed into the treated area.



LED red light therapy bulbs may last 100,000 hours, or 11.4 years, assuming the lights are turned on 24/7.


Low Heat Output

Red LED light therapy bulbs to produce just 10 to 20% of their energy as heat, making the technique cleaner, extending the device’s lifetime, and providing a pleasurable experience.



LED red light therapy bulbs lights are highly energy-efficient.

They provide the highest lumens per watt, which means they use less energy to produce greater light energy output than other types of bulbs.


With all that said, the greatest disadvantage of these therapy bulbs remains to be their low coverage & high initial cost when opposed to other light alternatives.

However, the yearly cost of owning a red light therapy bulb is quite inexpensive when you account for the spa sessions costs and the at-home privilege.


Solas gadgets come with Dual Spectrum. Meaning you get to have red light therapy AND infrared light therapy, both at the same time. Meaning, you get the added push to enhance your recovery even further, boost your cells, and spark your cellular vitality.

For common usage, SOLAS LED light therapy devices come with many benefits over your conventional variants of red light therapy bulbs and devices.


it is not always preferable for the receiver to be nearby the source of radiation. To reduce electromagnetic fields (EMF) exposure, studies recommend keeping at least 6 inches away

The Solas light panels produce very low EMFs, as it has hazardous effects.


Panel Output Power

It is critical to be aware of the recommended dosage. Check out your panel’s output power to get a clearer idea. 

The majority of these panels do not show this information. Solas, on the other hand, maintains full customer transparency is happy to give you the output power of your panel in watts so you can determine your intake.


Size of the Device : Treatment Area

Another point to keep in mind is that even if a gadget is theoretically capable of producing good effects, it may still be too tiny.

In other regards, a unit with a power density of, say, 100mW/cm2 might be a machine with a diameter of only a few inches and thus only produce light across a limited region of your body.


Overall, the device must emit light at a specific power density (light intensity), at the right wavelengths, at a suitable distance from your body. This is where the solar panels come in with their portability and convenient positioning.

Bottom Line

You saw the efficacy, the mode of use, the varying types of light therapy, and the benefits. So you should have an idea on what to get.

My advice would be to opt for RLT Bulbs only when you wish to enhance an existing portable RLT device’s efficacy or as an added bonus as an assisting therapy light but not for primary use

Red light therapy panels win this round. Specifically our HELIOS Shoulder Device.

Wish you find the right product and please let us know if we can be of assistance to you buying one of our devices.
