A genuinely affordable entry point, but be realistic: 14 LEDs on a wand delivers a fraction of the dose a 130 to 236 LED mask does.

The numbers brands hope you never check.
Every specification here is traced to the manufacturer's own page. Every irradiance figure is labelled as either their claim or somebody else's measurement, because on this equipment those two numbers are rarely the same.

660nm · 850nm60 LEDFDA unknown
Measured55 mW/cm2 average, 69 mW/cm2 peak at 6 in, measured by Alex Fergus (Light Therapy Insiders)
The value benchmark. Even after discounting the claim by the 25 percent independent testing found, it delivers more measured output per dollar than panels costing five times as much.

605nm · 630nm · 660nm · 855nm72 LEDFDA cleared
Not published
A 2010s-era device that keeps selling on warranty and clinical pedigree rather than specs. Fine for targeted work, slow if you want whole-face coverage.
- Longest warranty
- Spot treating specific lines
660nm · 850nm405 LEDFDA unknown
Brand claimBrand states greater than 70 mW/cm2 at the surface at 100 percent brightness. Distance and power level are both stated, which is unusually complete
A contact device, so its 70 mW/cm2 at the surface is legitimate but is not comparable to a panel figure taken at 6 inches. Was showing sold out at the time of research.
- Lower back
- Cordless use
- Clear spec disclosure

How this site ranks things
There is no proprietary score here, because a number like that is just our opinion wearing a lab coat. Rankings come from the specifications, and each page names the spec that decided the order. Where a manufacturer publishes nothing, the page says not published instead of guessing.

Does red light therapy actually work?
For some things, with reasonable evidence. Skin appearance and hair regrowth have the strongest published research, and hair devices have a genuine FDA clearance pathway. Pain and recovery evidence is promising but more mixed. Anything promising fat loss or disease treatment is running well ahead of the science.
What wavelength should I look for?
660nm red and 850nm near-infrared are the two best-studied wavelengths and appear in almost every serious device. Skin devices often use 633nm and 830nm instead, which is also well evidenced. Hair devices use 650nm to 680nm laser light specifically.
Why do you label irradiance as claimed or measured?
Because the gap between the two is routinely a factor of two. Brands measure at zero distance under ideal conditions and quote the peak. Where an independent tester has put a meter in front of a device we use their figure and say so.
Is an expensive panel better than a cheap one?
Less often than the prices imply. Measured output between mid-range and premium panels is closer than the marketing suggests. The premium usually buys build quality, extra wavelengths, warranty and support rather than dramatically more light.
