The Ultimate Guide to Red Light Therapy
For example, one study found that pulsing LED light at
40 Hz was optimal for promoting growth and activity in
bone-forming cells.
49
This frequency is also commonly
used in brain light therapy, showing promise in improving
brain connections and easing Alzheimer‘s symptoms.
A recent experiment on nerve-like cells found that pulsing
light 40 times per second was particularly effective in
boosting cell metabolism (the process by which your
body converts food and oxygen into energy).
49
Pulsing the light at 40 times per second with a 10% duty
cycle—meaning the light was on for only 10% of each
cycle—showed significant effects, even though the total
amount of light energy delivered over time was the same
as in other test conditions.
49
The study used both red (660
nm) and near-infrared (850 nm) LED light.
40 Hz
These findings highlight the potential importance of using a 40 Hz frequency in
RLT treatments, as it significantly influenced how cells responded.

If you‘re unsure about which light setting to use on your NovaaLab device, the steady light mode is generally a
good starting point. However, you might consider trying the pulsed mode at 40 Hz under two circumstances:
Overheating: If your device feels too hot during use, switching to the pulsed mode can help reduce heat
buildup.
Desired results: If you‘re not seeing the expected benefits from the steady light, experimenting with the
40-Hz pulsed mode might enhance your results. Some studies suggest this setting can optimize healing.
3.5 Which is Better: Visible Red Light,
Near-infrared, or Both?
One key factor in RLT’s effectiveness is how well the light can penetrate into our tissues. Scientists have
discovered that there‘s an „optical window“ in our bodies, ranging from 600 to 1350 nanometers (nm) in the
light spectrum.
34
In this range, which includes both visible red light as well as infrared, light can penetrate
deeper into our tissues because it‘s not easily absorbed or scattered by common body components like
blood, melanin (skin pigment), or water.
