Pulse Mode in Red Light Therapy:
What It Really Does
Same light, different rhythm. Here is what happens when your LED mask or panel starts to pulse, when it is worth it, and why one number keeps showing up in the research: 10Hz.
Same wavelengths, a different rhythm
In its default setting, your device runs in continuous mode: the LEDs stay on, steady, for the whole session. In pulse mode, the same LEDs switch on and off many times per second. The wavelengths do not change. Only the timing does.
That rhythm is measured in hertz (Hz). At 10Hz, the light flashes ten times per second, fast but still visible. Past roughly 60Hz, your eyes stop noticing and the light looks perfectly steady.
The light in your living room is already pulsing. On the UAE's 50Hz power grid, many lamps flicker 100 times per second. You never see it, but point your phone's slow-motion camera at one and the flicker appears.
What the research actually tells us
Scientists have compared pulsed and continuous light for decades. The honest picture fits in three points.
One of the most cited LED skin studies ever, the Montreal research behind the famous +31% procollagen result, used pulsed 660nm light, not continuous.6
Why 10Hz keeps coming up
10Hz sits right in the brain's alpha rhythm, the calm, eyes-closed brain wave first recorded by German psychiatrist Hans Berger in the 1920s, when he invented the EEG. Researchers are now exploring whether light pulsed at brain wave frequencies interacts with these rhythms, and early human studies at 40Hz have shown measurable changes in brain wave activity.7 It is a young, fast-moving field, and the most exciting place pulse control has to offer.
How pulse works on the mask and the panels
Which setting for which goal
| Your goal | Start with |
|---|---|
| Muscle recovery, joint comfort | Continuous, Muscle Recovery or Joint Pain mode |
| Skin, glow, anti-aging | Continuous by default, pulse if you prefer a cooler session |
| Sensitive skin, warmth | Pulse mode |
| Sleep, evening wind-down | Continuous, Sleep mode (no flicker before bed) |
| Focus sessions, biohacking | Custom slot: 10Hz for the body, 40Hz for head sessions, eyes closed |
New to your panel? Start with the preset modes and 5-minute sessions in week 1. Once you know how your body responds to continuous light, you will actually be able to feel what pulse adds.
If you have epilepsy or any history of light-triggered seizures, do not use pulse mode. If you are prone to migraines or sensitive to flicker, start with continuous light. And always wear the protective eyewear.
Is pulsed red light better than continuous?
What frequency does the Lumnae mask pulse at?
Does pulse mode lower the dose?
Is pulse mode safe?
- Pulse mode keeps the same wavelengths and changes only the rhythm.
- Both modes work. Continuous is the default for recovery, pulse is the cooler, rhythm-based alternative.
- 10Hz is the frequency that keeps standing out, and it is exactly what the Lumnae mask pulses at.
- Lumnae panels let you pulse each of the 9 wavelengths individually, up to 10,000Hz.

For readers who want to go deeper. Note that most direct pulsed vs continuous comparisons were run with lasers, and several in animal models.

Reference review (Massachusetts General Hospital): pulsed light produces effects that differ from continuous light, with no consensus on which is best or on optimal pulse settings.
