Inexpensive red light devices I use

As an enthusiast of red light / LLLT therapy, and also a cheapskate that would prefer to avoid spending $36k, I've cobbled together a collection of cheap at-home red light devices for specific purposes.

But first, two quick disclaimers:

  1. I think my general lighting section is useful for anyone, but the specialized devices in the following sections can have negative effects, so I'd advise against skipping the introductory information.
  2. I've added my Amazon referral to the Amazon links below. It gives me 4% for linking them at no cost to you.

Wave on a light spectrumIntroductory information and resources

Does red light therapy sound like something you'd see listed on the crumpled business card of that weird Breatharian guy in your yoga class? Yes. Do many proponents wildly overstate the benefits? Yes. Are skeptics skeptical? Yes. Is it clear that certain types of light have fairly well-studied effects on cells? Yes!Yes. Is it clear that certain types of light do something to cells? Yes!

To get a general overview of the ideas of red light / LLLT, Vladimir Heiskanen's overview is essential reading, particularly the first three sections. After that, I'd suggest skimming through Alex Fergus' overview/FAQ page because it answers a lot of the corner-case questions people tend to have.

From there, you may just be interested in skipping ahead to my general feel-good lighting section. But if you want to treat something specific with the more specialized devices, I'd suggest reading this article on "dosing" carefully, keeping in mind the concept that too high a dose can undo the good the light therapy was doing, or even become harmful.

Some additional learning resources:


Incandescent light bulb in a brooder enclosureIncandescents for general purpose, whole body, feel-good lighting

I use an approach mentioned by Ray Peat, with high-wattage incandescent lights as "personal lighting" in places where you'll be generally stationary, like desks or couches. Using 130V bulbs run on 120V North American household electricity shifts them more in the direction of the red part of the spectrum, and using brooder enclosures lets you safely run high-wattage lights angled directly towards your body.

This isn't what's usually meant by "red light therapy", but it makes for nice cheerful lighting while also containing some of the beneficial wavelengths in the more-specialized devices.

Bulb selection

I now order my bulbs online because they've become difficult to find locally. I specifically use:

PLT light bulb PLT 200PS30 from 1000bulbs.com. You can get six (with shipping) for around $30.

If you plan to use it near your face or around children or pets: These bulbs get very hot, and I had one shatter violently when it was hit with a tiny spritz of juice from an orange. So for any use where hot shards of glass would be more than inconvenient, I'd suggest the shatter-resistant version (thanks to Adam Capriola for finding this!).

If you look to purchase bulbs elsewhere, I'd suggest making sure they're:

Fixture selection

The actual fixtures you put the bulbs in are not important, as long as they are rated for the wattage of the bulbs you are using. Most household fixtures will be a fire hazard when used with high wattage bulbs, both because of the heat emanated from the bulb and the amount of power drawn.

Brooder fixtures

I use chicken brooder fixtures because they're inexpensive, easy to "point," and let me pretend I'm a farm animal. These are often available at big box hardware stores like Lowe's or Home Depot, typically in the $15-$20 range. If you order on Amazon, I'd suggest this one:

Bayco brooder light fixture Bayco SL-302B3. It's rated for up to 300 watts. You can also downsize to 150 watt products if you're using smaller bulbs. They also offer a baffling home installation service, the price of which suggests I need a career in brooder lamp installation.

Here's a few ideas on arranging them:

Brooder lamp hanging from ceiling by a chain
Top-down light with ceiling hooks and chain.
Brooder lamp hanging from ceiling by a chain, with wire to pull it into position
Horizontal light with ceiling hooks and chain, with wire for holding it at an angle.
Brooder lamp clamped to a shelf
Freely-angled light using a clamp (usually included with the fixture).
Brooder lamps surrounding a desk workspace
By combining these techniques, I'm able to surround myself with 600 watts of light while standing at my computer desk.

Photography light stands

If my approach of hanging the lights with chains and clamps alarms you, the older style photography light stands are a good option (thanks Marco!). However, they're becoming harder to find. Here's the only one I could find on Amazon:

Photographer's light stand RPS Studio Kit

Adam Capriola has also made a do-it-yourself adjustable stand guide that should be very inexpensive to make:

Large security light deviceLarge LED device for treating specific injuries or inflammation

These devices have a light panel that's about 4x2.5 inches. Resonant FM tested a nearly-identical device at around 45mW/cm2 (a useful amount of output) from the outside of the frame, typical of how you'd use it if it was resting on your body. That will drop off significantly at a distance, and there's no guarantee that the device you receive will be the same.

Ordering

The device plus a power adapter should run less than $40. I ordered this one off Amazon:

Large Aweek security light device Aweek 96 LEDs IR Illuminator

Depending on where you buy the illuminator, it may not come with a power adapter. You can probably save some money here with less-expensive options, but I go with a higher-amp, regulated power adapter in an attempt to prolong the life of both the adapter and the device. This is the most-affordable one I could find on Amazon:

12V 2A power adapter CMVision Power Adapter

Setup


Small security light deviceSmall LED device for smaller targets like thyroid, teeth

These devices have a light panel that's just under 2 inches in diameter. Resonant FM tested what is likely the same device at around 100-140mW/cm2 from the outside of the frame (typical of how you'd use it if it was resting on your body). The same disclaimers I mentioned in the larger device section apply to this one.

I've been experimenting with using on my teeth/gums and thyroid.

Ordering

The device plus a power adapter should run around $15. Here's the Amazon option:

Small security light fixture 48 LEDs IR Illuminator (currently $12)

Depending on where you buy the illuminator, it may not come with a power adapter. I'd suggest the same one as I did for the larger device.

Hypothyroidism, thyroid autoimmunity

I like Valtu's hypothyroidism article, and all of ResonantFM's articles on thyroid function and light:

There's also a neverending forum thread discussing people's experience treating hypothyroidism with it.

Pain and inflammation

This section is a bit of a placeholder because I haven't yet found a good general beginners guide to pain/inflammation treatment, but Resonant FM has a worthwhile read specifically for shoulder pain. However, it probably requires higher-end devices.

Testosterone

There's a long discussion here about people trying red light on the testicles to improve testosterone levels. However, I strongly suggest reading the cautionary threads here and here, particularly Sucrates' comments.

Oral health

Red Light Man has an accessible overview of the oral health studies.

Hair loss

It seems like there's a ton of interest in red light for hair loss, but I haven't come across across any good all-in-one guides. But here's a few resources from my notes:

Rheumatoid arthritis

As usual, Resonant FM has a great article on rheumatoid arthritis treatment.

Other conditions

Vladimir's ridiculously-huge spreadsheet with 3800+ studies is bound to have something to give you a lead on how a particular condition has been treated before, and whether the treatment was successful. Topics include acne, Alzheimer's disease, arthritis, autism, bone repair, brain injury, carpal tunnel, cellulite, cerebral palsy, circulation, cognitive performance, colitis, depression, diabetes, diabetic retinopathy, dry eyes, fibromyalgia, fractures, glaucoma, hearing loss, herpes, hypertension, inflammation, liver cirrhosis, macular degeneration, metabolism, microbiota, migraines, multiple sclerosis, myopia, osteoporosis, Parkinson's disease, psoriasis, Raynaud's syndrome, rosacea, scleroderma, stroke, tendinitis, tinnitus, and vitiligo.

Believe it or not, I really shortened that list of topics.
