If you’re picking a red light therapy panel for your home, irradiance- measured in milliwatts per square centimeter (mW/cm²)- is a key factor. It tells you how much light energy the panel delivers into your body at a certain distance. Getting the right level can improve effectiveness without causing discomfort. Here’s how to choose- and how the main brands stack up.

Why Irradiance Matters
• High irradiance means more energy delivered quickly- great for deep tissue healing or muscle recovery
• Lower irradiance is gentler- better for skin treatments and sensitive areas
• Too much light too close can irritate or overheat the skin
• Irradiance decreases with distance- so knowing your device’s output at realistic use distances (like 6–8 inches) is vital
Generally, experts recommend:
- 20–50 mW/cm² for skin health and beauty
- 50–100 mW/cm² for moderate pain management
- 100–200 mW/cm² or more for deep tissue and joint therapy
Some sources note 100 mW/cm² as a common benchmark, though others caution that much lower levels may still be effective- or safer- especially for full-body panels
How the Brands Compare on Irradiance
Let’s look at major brands one by one and how their panels perform in terms of power output:
RLT Home (Total Spectrum Ultra / MINI)
At 8 inches, the Total Spectrum Ultra delivers around 174 mW/cm², which is one of the highest certified irradiances on the market using a spectrometer. Great for deep tissue needs.
Mito Red Light
Mito occasionally shares figures like 200–250 mW/cm² at 6 inches in professional testing, though consumer meters can vary (they don’t say which meter has been used). They focus on delivering strong and clinically tested output.
Infraredi
While exact numbers aren’t always in the user guide, Infraredi emphasizes control over brightness and pulsing, implying they aim for coloring above typical skin levels- likely 50–100 mW/cm² or higher.
PlatinumLED, Joovv, Kala
These trusted brands generally offer moderate to strong output for home use. Experienced users commonly estimate values around 40–60 mW/cm² at 6 inches for masks or small devices; bigger panels can get much stronger.
Hooga, Block Blue Light, Rojo, Rouge, Bon Charge, Scienlodic, Red Light Rising
These tend to aim for skin health or targeted use. Their panels usually provide 20–80 mW/cm² at recommended distances- safe for daily use and focused areas.
Recommended Irradiance Levels by Use
For skin health, anti-aging, and a natural glow, you should look for an irradiance of about 20 to 50 mW/cm². This is gentle enough for sensitive areas like the face and works best at around twelve inches from the panel.
For pain relief and reducing mild inflammation, aim for 50 to 100 mW/cm². This usually means sitting about six to eight inches away from your panel. It’s strong enough to reach below the skin surface without being overwhelming.
For deep tissue work- like joints, muscles, or arthritis support- you want at least 100 mW/cm², and ideally up to 200 mW/cm² or more. To get that kind of power, you’ll usually need to position yourself closer, around six inches from the device, and keep sessions consistent.
Always remember: the total energy dose (fluence) is what matters most. A good target is around 10 to 25 joules per square centimeter. For example, if your device delivers 50 mW/cm² and you use it for five minutes, that equals about 15 J/cm², which is right in the recommended range.
Final Thoughts
- Look for a panel that lists irradiance at realistic distances like 6–8 inches.
- For deep results like muscle repair or arthritis, go for 100 mW/cm² or more.
- For skin health or general wellness, 20–50 mW/cm² is often plenty.
- RLT Home panels lead in raw irradiance (174 mW/cm²), while other brands still deliver good strength tailored to different goals.
- Be sure to use the panel at a safe distance, account for session time, and follow simple dose math: irradiance × time = energy delivered.
