How to Choose Red Light Therapy Bulbs for Optimal Benefits

One of the most important decisions you’ll make when you begin red light therapy at home is the type of device and light bulbs you’ll need to get started.

When you decide to enjoy the benefits of red light therapy, you’ll see noticeable improvements in reducing pain and inflammation, relief from sun damage, greater hormonal balance, and increased hair growth. 

Top Factors to Consider When Choosing Red Light Bulbs

When you choose red light bulbs for your device, you’ll maximize the benefits of rejuvenating cell performance by producing more collagen and elastin while promoting healing and anti-aging results for clear, healthy skin. 

Frequency Range

Most red light therapy devices produce a frequency ranging from 633 to 850 nm. This range refers to the type of light from 633 nm, where red light produces that penetrates skin and stimulates mitochondria, to 850 nm, which produces near-infrared light that targets deeper into the tissue. The device you choose along this range depends on the degree of effects you require.

Red light therapy is often the best choice for increasing collagen production to slow aging and healing your skin from scarring due to scarring and other skin issues. Near-infrared light penetrates deeper, which can help relieve chronic conditions, such as joint and muscle pain, and deeper wounds or injuries.

Irradiance or Energy Level

When you use a red therapy device, it emanates a certain level of energy that your body receives throughout the duration of the treatment. The amount of energy delivered is measured as irradiance, which encompasses distance and the irradiance level. When you choose a device with a higher level, you’ll likely notice results in a shorter time. 

Device and Light Bulb Quality

You’ll find many red light therapy devices on the market, which vary from portable, inexpensive desktop lamps to large-scale devices that require equipment, tools, and space to set up for use. Always research the product name, standards, and certificates to ensure the device is genuine and meets health and safety standards. 

Choosing the right device also includes bulbs; you’ll want to purchase good quality lights for the best results.

Area of Coverage

How much coverage do you require from your red light device? Are you looking for smaller bulbs or lighting for a specific region or a large panel that targets the entire body? Maximum exposure is ideal for treating hormonal imbalance, joint pain, and muscle recovery. A smaller device is more suitable for treating wrinkles, scarring, stretch marks, and specific body parts.

Product Reviews and Feedback

Before buying, read customer reviews and feedback to understand better which red light therapy lights work best. Some customers will detail their experience with the intensity of light, how effective it was in treating their skin condition, and whether the device is durable or prone to damage easily.

Purchasing a red light device is an important investment, so you’ll want to know exactly what you’re getting, the level of customer support, and whether there is a warranty or an option to return or exchange the item.

Choosing Red Light Therapy Bulbs Suitable for Home

While you don’t have to spend much on red light bulbs, quality is crucial for the best results. You may find some products that offer the strength and size you need for your red light therapy device. However, it’s important to find one that’s suitable for a home sauna or setting while, at the same time, choosing a bulb with medical-grade quality.

Bulb Types and Sizes

While red lighting is used in various lights, including incandescent, halogen, fluorescent, and LED or light-emitting diode bulbs, only LED lighting produces the wavelengths of red light for therapeutic benefits. 

Incandescent and halogen light bulbs produce a continuous spectrum, producing bright or warm light. The only way to produce specific light colors is by tinting the glass, which doesn’t provide the same therapeutic benefits. They also burn a lot of energy and have been associated with causing health problems.

Fluorescent lighting is often the less expensive option for red light therapy and is often used in gyms or spas because they save on operating expenses. Not only are they ineffective in providing any therapy, but they also produce light by charging mercury gas, which must be disposed of carefully once they burn out.

Why LED Lighting is Best for Red Light Therapy

LED lighting technology was first introduced in the 1960s and has become one of the safest, most energy-efficient, and long-lasting options for lighting. LED technology is ideal for red light therapy, as it produces the required wavelengths to produce therapeutic red light. They produce less energy, low heat, and focus directional light, so you get exactly what you need for the specific therapy you require.

LED bulbs are highly durable because they don’t shatter and are easy to maintain for many uses. While LEDs can produce visible light from the entire spectrum, they can also be designed to produce specific wavelengths for a range of health benefits. These bulbs contain no toxins, so you’ll never be exposed to mercury or other dangerous gases.


Quality, design, and size are all integral when choosing a red light therapy device and light bulbs. LED red light therapy is available in many formats, for large red light device installations or portable, convenient kits. It’s always best to review the quality and customer feedback before you choose bulbs for your device to ensure they provide the desired effects of your treatment.
