1. Nothing in this note is to be construed as “medical advice.”  This is informational, about something called low level laser light therapy.
  2. Since I have been using LLLLT (also known as LLLT, a/k/a/ photobiomodulation) I have personally experienced health benefits including the virtual elimination of eczema which I’ve suffered through for 70-years…


Down to just a few days until I am “Out of the Penalty Box” following the naval hernia / mesh implant.  Although I’ve been feeling great, it’s time to find new and interesting ways to fill “retirement.”  Back into the lab…Oh, and back on my “light crown.”

The knowledgeable reader – someone who has been around this site for years – may be able to tell when I’ve been “on the light crown.” Articles written have more spark and originality to them.  I can sure tell when Elaine is not using the version 3.0  Light Helmet.

If none of this makes sense, fair enough.  Let’s see if I can condense five years of personal research into a short, logical flow.


light crown, or light helmet, is an arrangement of light-emitting diodes typically worn for about 20-minutes per day.  Power levels are under 5 joules per square centimeter. LED colors selected change the effects.  Deep infrared (longer than 700 nm) penetrates tissue deeper.

The US government’s PubMed medical database, as of this morning, lists 6,090 studies containing the search term LLLT.  940 studies are returned in a search for “photobiomodulation.” And, to give you a sense of the breadth of application for “light therapies” here are some recent article titles to consider:

No, I did not pop the $51-bucks to read this last item, but it’s included in the list to illustrate the breadth of the field.

A “Light History” and the Medicine

Light is powerful stuff.  The gospels of Matthew and John both reference Jesus’ “ I am the Light of the World.”  While not a “thumper”  per se, I’ve studied the Bible enough to become something of a  literalist.  Might be something to this “light” stuff – like enlightenment.

There is a huge increase in scientific study of the field.  We know that under stress, “In vivo imaging of spontaneous ultraweak photon emission from a rat’s brain correlated with cerebral energy metabolism and oxidative stress..”  Human translation:  Odds are good that when you are stressed, you lose your Light.

It goes much deeper:  A landmark (virtually unheralded) paper went much further, suggesting the “Possible existence of optical communication channels in the brain.”  To those of us who have been tinkering in the field for a while (doing a bit of self-science) there seems to be some value to “light pumping.”  In other words, flooding the body with light.  Specific colors (corresponding to frequencies) and in controlled amounts.

In my first light crown build (2016), I used multiple LED’s.  Red, blue, and green arrays were placed over my trigeminal nerve packs.  These are the nerve bundles associated with the temples on either side of the head:

The left highlight is where one LED array was placed .  Another was in the center.  The third was on the opposite side of the head.

The addition of light emitting diodes in these locations may impact how sensitive people feel.  There is a difference in effects depending on light frequencies and even the types of LEDs used.

Device Construction

The light crown  build is fairly straight-forward as I explained in my book Dimensions Next Door in 2017.  Any number of approaches can place the light arrays where they need to be:  Extra-wide headbands are simple and less messy than 2-inch wide stretch material with arrays attached with Shoe Goo.  In the all-fabric model, Velcro cinches the headband firmly in place.

A basic unit uses  four LEDs per location for a total of 12.  The LED’s used are generally of the 2.5-3.0 volt range and current consumption is about 20 milliamps per device.  Depending on how it’s wired, 240 milliamps at 3 volts.  Pushes out to (12 devices * 0.02) = 0.24 amps.  Which times 3-volts gets us to 0.72 watts.  The calculation to a target range of 4-4.5 Joules per square centimeter proceeds from here.

Historical Crowns & Light

Kings and queens wear ’em, right?

What seems likely is that “crown jewels” were possibly not selected based on ‘imaginary values.’  “Crown jewels” may have provided enhanced mental function by controlling specifics light frequencies illuminating specific parts of the head.  Until, the technology blurred in ancient times and the backs of crowns became padded such that light didn’t pass through them any longer.

The role of light in human psychology is widespread and dispersed across multiple human belief systems.  In particular, almost no one (except the earnest student) has ever heard of Shahab al-Din Suhraward.  But his work is particularly germane to present-day research because the hundreds of light-based devices undergoing clinical trials (see  That’s because:

“In his Philosophy of Illumination, Suhrawardi argued that light operates at all levels and hierarchies of reality (PI, 97.7–98.11). Light produces immaterial and substantial lights, including immaterial intellects (angels), human and animal souls, and even ‘dusky substances’, such as bodies.

We have had this discussion before:  Under the law of conservation of energy, and knowing that when a person dies that “personal energy” has to go somewhere, a “soul’s worth of photons” might well “beat retreat” into other photonic (and likely holographic) energy realms.  Dimensions Next Door, and my book on this was titled.

Moreover, Islam is not alone in the study of light in theological affairs:

“In theology, divine light (also called divine radiance or divine refulgence) is an aspect of divine presence, specifically an unknown and mysterious ability of God, angels, or human beings to express themselves communicatively through spiritual means, rather than through physical capacities. “

The point my constructing and use of a personal “light crown” has been to improve personal well-being and (spiritual) awareness.

Elaine and I have been using our light crown (and light helmet) for over a year now and we haven’t experienced any ill effects.  I’m keeping particular tabs on a study at the University of Texas that is using a longer-wave length laser in a test to see if it can improve mild cognitive impairment.  Study should be completed next year.

Elaine’s age-related macular degeneration appears to have been successfully treated in a five-year home protocol similar to the Lumithera devices now being trials in Europe.  Their (EU-facing) science page here is particularly good at explaining the mechanics of LLLLT/PBM to newcomers.  And there’s my now-missing eczema, too.

A Light Crown vs. Speed Crown

Olde Man Labs here has been pursuing two essential tracks.  The first is oriented toward single and dual frequency long wave light sources.  Deep red, in the 660 nm to 700 nm (super red) range seems to optimized a lot of health issues.  For deeper penetation into tissue, longer wavelengths are used.

Our experiments have involved 660 nm red light alone, or in concert with 850 nm infrared.  Think of this as a “conventional” light crown.

The second track is the multifrequency (multi-color) track.  This is speed crown territory.  Shorter wave lengths.  Colors, sure, but we stay well clear of the UV range for obvious reasons.  Nothing higher than 380 nm, for sure.  *(Violet/Purple).  My next build will be a purple (400 nm area) and 523 nm green.

Applying green light to the right temple, red to the center of forehead, and blue or purple to the left temple gives me a slowly developing “rush” over several sessions.  It takes five or six days to evolve, but after that, there’s so much personal energy flowing it’s almost like being in an episode of “Limitless” or on speed.

When the first “speed crown” broke (RGB), I figured it would be a good idea to set it aside for a while and focus more on the healing (660-850 nm) light spectrum.

Since our studies began, a number of commercial products have come to market that may be useful.  Rather than build up your own array, for example, you can find a therapy array on Amazon: SGROW 24W Red Led Light Red 660nm and Near Infrared 850nm Led Light Therapy Bulbs for Skin and Pain Relief.  $40 bucks, it’s not cheap, but do read the reviews.

On the other hand, if you want to experiment with different effects? here we come…

Part of my collection of leaded (through-hole) LEDs.  There are two good-sized project boxes worth.

One useful learning point:  Don’t get diffused LED’s – narrow viewing angles are fine but diffused LEDs don’t seem to work as well.  Water-clear lens are what you’re after.  The whole point of laser light is its coherence.  What happens when you diffuse?

Although I’ve been writing about this emerging technology both in books and on the Peoplenomics side of things, the tech is slowly becoming recognized.  A good article over on SelfHacked (here) may convince you that Ure hasn’t completely flipped-out.  Too much soldering smoke?

The takeaways from this morning’s update include the following:

  • We’ve been using the red light therapy on the head for a year with no ill effects.
  • The science is going mainstream as a complimentary/alternative therapy..
  • Red light bulbs though pricey get good reviews on Amazon and are an alternative to red/infrared devices.
  • Speed crowns pumping other wavelengths are still in the DIY column..
  • And (the key part) is that certain mixes of light, when applied daily for 20-minutes, subjectively increase personal energy.
  • So a year (or three) from now when “energy crowns” come out, remember this is all prior art.

For me the effect is so profound there’s almost a feeling that if I don’t consciously slow-down, I’ll burn up in the atmosphere.

With the baseline reaction speed of 0.34259 seconds tested over here (slow internet here!) I will see what – if any – actual change there is with a speed crown in a few weeks…  Should be interesting…

Meantime, outfits like  Thor Laser, and others, are selling sophisticated devices and we expect more device companies will follow.  We keep hearing things about how a “red light bath” can improve athletic performance, too.  No telling how long before pro sports puts light therapy use on their watch lists…
