I've seen plenty of red light exposure masks / therapies / tools being sold for absurdly high prices. I'm pretty suspicious of them, not least because I don't know much of anything about this area.

Has anyone gone down the rabbit hole here and have genuine product recommendations that roughly satisfy the conditions laid out in the paper? * Wavelength: 650–900 nm red light * Power output: 8 mW/cm² * Misc design choices: e.g. light diffusers * what other considerations???

I actually found the cheapest and best solution: getting 30 minutes of direct sunlight every day

Challenge there is limiting exposure to damaging UV rays while maximizing near IR

Perineum?

[heyoni]

You won’t get an answer. They’ve been arrested for indecent exposure

[hart_russell]

I think shorts and minimal top would suffice lol

I know some old eastern europeans who just swear by the red heat lamp. Like a big hot bulb akin to something for rotisserie chicken. I imagine its like a targeted hot tub in terms of muscle relief.

I would not recommend applying a heat lamp to your eyes.

There are some infrared masks which gently warm the eyelids to "melt" the meibomian oil in the eyes, which improves lubrication and can really help with dry eyes and associated fatigue. No clue about their wavelengths, but those are generally pretty cheap.

These people have been doing clinical work for 30 years. check the Science and webinar tabs in the top menu. PBM works for me. Make up your own mind... FDA Clinical grade equipment is not cheap. https://bioflexlaser.com/ They developed a consumer line of equipment last year. https://bioflexwave.com/ Nano will work for PTNS (and more). I have no financial relationship with these people but so far the equipment cost is worth the help with medical issues.

Mitsubishi makes the best leds. get ones made by them. the rest can be driven by whatever

[heyoni]

Maybe, maybe not. At power levels high enough to be therapeutic you’re gonna want to think about cooling.

I recently bought a panel on AliExpress for much cheaper than most of the branded one. There's not really reason for them to lie about the wavelength of the LEDs, so build quality is really the only risk factor.

[pseudosaid]

just lie about the led itself as that is the costly component. Who is gonna measure wavelengths and hold them accountable? its a no brainer move to scam the most expensive component that also is hard to verify

[goda90]

Are LED's particularly costly though? Does one wavelength of red LED differ significantly in price from another wavelength of red LED? And does that even matter that much? It seems like higher wavelength has deeper penetration, but how deep you want depends on use case.

[literalAardvark]

You would get deeper penetration from very high power leds driven intermittently though.

So there may be a very different grade of led in the pricy stuff.

i bought https://platinumtherapylights.com/products/bio-rlt?variant=1... during the pandemic, it has held up.
