Using a red light therapy pad effectively isn't about turning every setting to maximum. Wavelength, intensity, treatment time, placement, and consistency all influence how much light your body receives, so understanding how these factors work together can help you use your device more intentionally.
The Novaa Light Pad combines 660 nm red light and 850 nm near-infrared (NIR) light in a flexible pad designed to sit directly against the treatment area. Its 450 LED light chips (150 at 660 nm and 300 at 850 nm) provide up to 150 mW/cm² of measured irradiance at direct contact, with adjustable intensity and both steady and pulsed modes. It also comes with a stretchy strap to hold the pad in place and an option to add a battery pack for cord-free use.
But those specifications are only useful if you understand what they mean in practice. In this guide, we'll first walk through how to use the Novaa Light Pad, which settings to choose, and how long and how often to use it. Then we'll break down the science behind those recommendations, including how wavelength, irradiance, distance, and treatment time affect light exposure, and why more isn’t always better with red light therapy.

Using the Novaa Light Pad: Overview
Using the Novaa Light Pad means placing it directly against clean, bare skin, selecting your preferred light and mode settings, and completing a 20-minute session. The pad is designed to make your treatment routine simple, with adjustable settings that let you tailor the session to your needs and comfort.
| Light Pad Setting | General Guidance | Why It Matters |
|---|---|---|
| Placement | Position the pad directly against clean, bare skin. | Direct contact maximizes light delivery and avoids the substantial drop in irradiance that occurs as distance increases. |
| Wavelengths | Use 660 nm red + 850 nm near-infrared light together for most general applications | The two wavelengths provide light exposure across superficial and deeper tissue layers. |
| Mode | Choose steady or pulse based on your needs and comfort. | Steady provides continuous light and higher average output, while pulse provides intermittent light with less heat. |
| Intensity | Choose a comfortable intensity rather than automatically using the maximum. | Intensity controls how quickly light energy is delivered; lower the setting if higher intensities cause discomfort. |
| Session Length | Start with the standard 20-minute session. | The built-in timer automatically shuts the pad off after 20 minutes. |
| Frequency | Use once daily as the standard routine unless otherwise advised. | Consistent use matters, but increasing treatment frequency doesn't necessarily produce better results. |
| Consistency | Follow a regular routine rather than compensating with excessively long or intense sessions. | Red light therapy follows a dose-response relationship, so the goal is appropriate and consistent exposure, not simply as much light as possible. |
These are general starting guidelines rather than a universal treatment prescription. The appropriate settings can vary based on what you're treating, your individual response, and guidance from your healthcare provider.
How to Use the Novaa Light Pad Step-by-Step
Once you've chosen the area you want to target, setting up the Novaa Light Pad only takes a few steps. The process below walks you through placement, wavelength and mode selection, intensity, treatment time, and aftercare so you can establish a consistent routine.
-
Position the light pad against bare skin. Place the Light Pad directly against clean, bare skin over the area you want to target, such as your back, shoulders, arms, legs, or joints. Use the included strap if needed to keep it securely positioned.
-
Choose your wavelengths. For most general applications, use 660 nm red light and 850 nm near-infrared light together. The two wavelengths reach tissue differently, with 660 nm providing more superficial exposure and 850 nm offering greater tissue penetration. You can also use either wavelength individually. If using both initially feels uncomfortable, we recommend starting with red light, then trying near-infrared before progressing to both together.
-
Choose steady or pulse mode. Choose steady mode for continuous light delivery and a warmer sensation or pulse mode for intermittent light delivery with less heat. Neither mode has been established as universally better, so your comfort and preferences can help guide your choice.
-
Set a comfortable intensity. Choose an intensity that feels comfortable rather than automatically using the highest setting. Higher intensity delivers light energy faster and generates more warmth, but higher isn't necessarily better. If the pad becomes uncomfortably warm, reduce the intensity.
-
Complete your 20-minute session. The Light Pad's default timer automatically turns the device off after 20 minutes. Avoid extending sessions simply to increase your exposure; treatment time and intensity work together to determine how much light energy is delivered.
-
Repeat consistently. Our standard guidance is one 20-minute session per day. Focus on maintaining a consistent routine rather than adding longer or more frequent sessions in an effort to accelerate results.
-
Clean and store your pad. After your session, unplug the Light Pad and wipe it with a cloth lightly sprayed with alcohol or an antibacterial wipe. Never submerge the pad in water, and avoid getting moisture near the connection port before storing it in a dry place.
Why the Novaa Light Pad Uses 660 nm + 850 nm Wavelengths
The Novaa Light Pad combines 660 nm red light and 850 nm near-infrared (NIR) light to provide light exposure across both superficial and deeper tissues. Both wavelengths fall within commonly studied photobiomodulation (PBM) ranges, but differences in how they travel through tissue make them useful for different treatment targets. A review of PBM treatment parameters notes that red wavelengths from 600nm to 700 nm are generally better suited to superficial tissues, while wavelengths from 780nm to 950 nm are preferred when deeper penetration is needed.
660 nm Red Light: Best Suited to Superficial Tissues
660 nm red light is particularly relevant when the treatment target is closer to the skin's surface. Red-light PBM is commonly studied for skin and superficial tissue applications, including cellular processes associated with inflammation, collagen production, circulation, and tissue repair. Because 660 nm is visible, these are the Light Pad chips that produce the bright red glow you see during treatment.
850 nm Near-Infrared Light: Greater Tissue Penetration
850 nm near-infrared (NIR) light penetrates farther into tissue, making it particularly relevant when targeting deeper structures such as muscles, joints, and tendons. Near-infrared PBM is commonly studied for applications involving muscle recovery, musculoskeletal discomfort, inflammation, and tissue recovery. 850 nm falls outside the visible spectrum, so the NIR chips may appear dim or unlit even though they're operating normally.
The Benefits of Combining 660 nm + 850 nm
Using both wavelengths allows the Light Pad to provide red and NIR exposure during the same session rather than limiting treatment to one tissue depth. The Novaa Light Pad contains 450 light chips in total, with 150 chips at 660 nm red light chips and 300 chips at 850 nm NIR light chips.
This dual-wavelength approach gives users flexibility to address both superficial and deeper treatment targets. However, it shouldn't be interpreted to mean that combining wavelengths is inherently more effective than using a single wavelength for every application. The appropriate PBM parameters ultimately depend on the treatment target and goal.

The Factors That Determine Red Light Therapy Strength
The strength of a red light therapy treatment depends on more than wattage or the number of LEDs. Wavelength, irradiance, treatment time, distance, intensity, and mode all influence how light is delivered, which is why comparing a single specification rarely tells you how two devices or treatment sessions actually compare.
A review of photobiomodulation treatment parameters identified irradiance and energy density as particularly important variables while also noting that wavelength, power, pulse mode, treatment duration, and repetition can influence PBM outcomes.
| Specification | What It Tells You | What It Doesn't Tell You |
|---|---|---|
| Wavelength (nm) | Type of light being delivered and how it interacts with tissue | How much light is delivered |
| Irradiance (mW/cm²) | Rate at which light energy reaches a given area | Total light exposure over the session |
| Treatment Time | How long the area is exposed to light | Total dose without knowing irradiance |
| Energy Density (J/cm²) | Amount of incident light energy delivered per unit area over time | How much energy is ultimately absorbed by deeper tissue |
| LED Count | Number and density of light-emitting sources | Treatment dose or effectiveness |
| Wattage | Electrical/device power | How much light actually reaches the skin |
| Distance | How far the light source is from the treatment area | Treatment effectiveness on its own |
The takeaway is simple: Don't judge a red light therapy pad by its wattage or LED count alone. Measured irradiance, wavelength, treatment time, and how the device is actually positioned all provide important context for understanding light exposure.
Comparing Higher- and Lower-Powered Red Light Therapy Pads
The Novaa Light Pad is designed to deliver relatively high light output while still giving users control over intensity. Its 450 light chips combine 660 nm red and 850 nm NIR light, while its measured irradiance reaches 150 mW/cm² at direct contact. This allows light energy to be delivered relatively quickly across the treatment area, while adjustable intensity lets users reduce the output when needed for comfort.
Lower-powered pads can still deliver a meaningful dose, but lower irradiance means it takes longer to deliver the same amount of incident light energy. For example, at 50 mW/cm², reaching a calculated dose of 50 J/cm² would take about 17 minutes. At 150 mW/cm², that same 50 J/cm² can be reached in about 5.6 minutes.
When comparing red light therapy pads, output should be considered alongside treatment time, wavelength, and dose. This is why measured irradiance is more useful than simply comparing wattage or LED count: It helps show how quickly a given amount of light energy can be delivered to the treatment area.
Understanding Your Red Light Therapy Dose: Irradiance, Distance, and Treatment Time
The amount of light delivered during a red light therapy session depends on both irradiance and treatment time. With the Novaa Light Pad, irradiance decreases substantially as you move the device away from your skin. Irradiance measures the rate at which light energy reaches a given area, so a higher mW/cm² means energy is being delivered more quickly, not necessarily that the treatment is more effective.
Calculating Your Dose
To estimate the incident light energy delivered over a session, you can multiply irradiance by treatment time:
Irradiance (W/cm²) × Time (seconds) = Energy density (J/cm²)
For example, the Light Pad's 150 mW/cm² contact irradiance is equivalent to 0.15 W/cm². Over the standard 20-minute (1,200-second) session:
0.15 W/cm² × 1,200 seconds = 180 J/cm²
This chart shows how the calculated incident energy changes over the same 20-minute session as distance increases. While the light pad is meant to sit on your skin, a light panel is not. If you’re deciding between the two, make sure you understand how much energy is delivered at a distance.
| Distance | Irradiance | Calculated Incident Energy in 20 Minutes | Practical Context |
|---|---|---|---|
| 0" | 150 mW/cm² | 180 J/cm² | Standard placement; delivers the full measured surface exposure |
| 1" | 120 mW/cm² | 144 J/cm² | Delivers ~80% of the direct-contact exposure |
| 3" | 45 mW/cm² | 54 J/cm² | Delivers ~30% of the direct-contact exposure |
| 6" | 25 mW/cm² | 30 J/cm² | Delivers ~17% of the direct-contact exposure |
There isn't one J/cm² dose that's considered effective for every application. The appropriate dose varies based on treatment goal.
More Light Isn't Always Better
A higher dose doesn't automatically produce a better biological response. Photobiomodulation research describes a biphasic dose response, meaning too little light may not provide enough stimulation, while increasing exposure beyond an effective range may cause the response to plateau or diminish.
That's why the goal isn't to maximize irradiance, treatment time, and frequency at once. For standard Light Pad use, position the device directly against the skin and follow the recommended treatment protocol rather than increasing session length to chase a higher dose.
Steady vs. Pulsed Red Light Therapy
Neither steady nor pulsed red light therapy has been established as universally better; the right setting can depend on the treatment parameters, application, and individual preference. On the Novaa Light Pad, steady mode provides continuous light, while pulsed mode is available at 10 Hz and 40 Hz, meaning the light cycles on and off 10 or 40 times per second.
| Steady Mode | 40 Hz Pulsed Mode | 10 Hz Pulsed Mode | |
|---|---|---|---|
| Light delivery | Continuous | Cycles on and off 40 times per second | Cycles on and off 10 times per second |
| Average output | Higher | Lower due to intermittent delivery | Lower due to intermittent delivery |
| Heat | Typically warmer | Typically cooler than steady mode | Typically the coolest mode |
| Best for | Users who prefer continuous delivery, higher average output, or more warmth | Tissue repair, muscle recovery, and longer-term recovery | Relaxation, discomfort, and everyday pain management |
Research suggests pulsed and continuous PBM can produce different biological effects, but there isn't enough evidence to identify one as consistently superior or to establish 10 Hz or 40 Hz as an optimal frequency for a particular outcome. A review comparing pulsed and continuous PBM found that pulsed light performed better in some studies, while continuous light performed equally well or better in others with no optimal pulse frequency established.
For now, the best approach is to choose the mode that aligns with your needs and feels most comfortable during treatment. Novaalab recommends 10 Hz for relaxation and everyday discomfort and 40 Hz for tissue repair and recovery, while steady mode is a practical option when you prefer continuous light delivery and higher average output.
Common Red Light Therapy Misconceptions
More power, more LEDs, more heat, or more treatment time don't automatically make red light therapy more effective. This chart lists some of the most common misconceptions to keep in mind.
| Myth | Reality |
|---|---|
| More LEDs mean a better pad | LED count can affect coverage, but it doesn't tell you the light energy produced. |
| Invisible NIR LEDs aren't working | 850 nm NIR light is outside the visible spectrum, so the LEDs may appear dim even when working normally. |
| Longer sessions produce better results | Longer treatment increases your dose, but more exposure isn't necessarily more effective. |
| Pulsed light penetrates deeper | There's insufficient evidence that the Light Pad's pulse mode penetrates deeper than steady light. |
| More heat means a stronger treatment | Warmth isn't a reliable measure of effectiveness. |
| Higher wattage means more therapeutic power | Electrical wattage doesn't tell you how much light actually reaches the treatment area. |
Red Light Therapy Pad Safety Considerations
Red and near-infrared photobiomodulation is generally considered safe when used appropriately with serious adverse effects uncommon in clinical research. A 2025 evidence-based clinical consensus on PBM similarly concluded that PBM is a safe treatment modality for adults, although the appropriate protocol depends on the individual and application.
When using the Novaa Light Pad:
-
Follow the recommended treatment time and settings rather than assuming more exposure will produce better results.
-
Reduce the intensity if treatment becomes uncomfortably warm.
-
Use extra caution around the eyes and follow the device's eye-protection instructions.
-
Talk to your healthcare provider before use if you're pregnant, take photosensitizing medications, have a medical condition that could affect your response to light therapy, or plan to use the pad to treat a specific health condition.
The Light Pad provides general at-home red light therapy rather than individualized medical treatment. Consult your physician or another qualified healthcare professional for guidance on appropriate use based on your specific needs, medications, and treatment goals.
