Google 660nm benefits or 88nm and you will find plenty of info.
Here's a site about an expensive appliance but it has interesting
information
http://www.anodynetherapy.com/Clinical.htm
this site has some interesting photos of increased circulation in
extremities with poor circulation, Anodyne therapy seems to consist of
a type of infrared, I'm not sure if they mention the wavelength.
You might be interested in this website. I found it by googling NASA
660 nm 880 nm (wavelengths of LED red and infrared lights) and clicking
on cached. The LED's shown are 660nm as 880 nm is not visible.

Light emitting diodes bring relief to young cancer patients; NASA
technology used for plant growth now in clinical trials

wound healing in bone marrow transplant patients.
A device using specialized light emitting diodes, based on NASA
technology for plant growth in space, is continuing to show promise as
a treatment to aid healing of bone marrow transplant patients. Use of
the LED apparatus has advanced to the second phase of clinical trials
in U.S. and foreign hospitals. Results from the first round of tests
were highly encouraging, prompting researchers to expand the trials as
they seek approval for the treatment as a standard of care for oral
mucositis.

A nurse holds a strange-looking device, moving it slowly toward a young
patient’s face. The note-card-sized device is covered with glowing red
lights, but as it comes closer, the youngster shows no fear. He's
hopeful this painless procedure using an array of lights will help ease
or prevent some of the pain and discomfort associated with cancer
treatment.
The youngster is participating in the second phase of human clinical
trials for this light healing device. The first round of tests by
Medical College of Wisconsin researchers at Children’s Hospital of
Wisconsin in Milwaukee, was so encouraging that doctors have expanded
the trials to several U.S. and foreign hospitals.
“We've already seen how using LEDs can improve a bone marrow transplant
patient's quality of life," said Dr. Harry Whelan, professor of
neurology, pediatrics and hyperbaric medicine at the Medical College of
Wisconsin in Milwaukee. "These trials will hopefully help us take the
next steps to provide this as a standard of care for this ailment.”
The light is produced by light emitting diodes, or LEDs. They are used
in hundreds of applications, from electronic clock displays to jumbo TV
screens.
These LEDs provide light for plants grown on the Space Station as part
of commercial experiments sponsored by industry under the Space Product
Development Program at NASA’s Marshall Space Flight Center in
Huntsville, Ala. Researchers discovered that the diodes also had many
promising medical applications, prompting this research to be funded by
a NASA Small Business Innovation Research contract through the
Technology Transfer Department at the Marshall Center.
Biologists have found that cells exposed to near-infrared light — that
is, energy just outside the visible range — from LEDs grow 150 to 200
percent faster than those cells not stimulated by such light. The light
arrays increase energy inside cells that speed up the healing process.
In the first stage of the study, use of the LEDs resulted in
significant relief to pediatric bone marrow transplant patients
suffering the ravages of oral mucositis, a common side effect of
chemotherapy and radiation treatments according to Dr. David Margolis,
associate professor of pediatrics at the Medical College. He works with
Dr. Whelan on the study at Children’s Hospital of Wisconsin, a major
teaching affiliate of the Medical College.
Many times young bone marrow transplant recipients contract this
condition that produces ulcerations in the mouth and throat, severe
pain, and in some cases, inflammation of the entire gastro-intestinal
tract. Swelling and bleeding occur, and chewing and swallowing become
difficult, if not impossible — affecting a child's overall health
because of reduced drinking and eating.
"Our first study was very encouraging, and using the LED device greatly
reduced or prevented the mucositis problem, which is so painful and
devastating to these children," said Whelan. "But we still need to
learn more. We're conducting further clinical trials with larger groups
and expanded control groups, as required by the U.S. Food and Drug
Administration, before the device can be approved and available for
widespread use."
The clinical trials are expected to take approximately three years with
a total of 80 patients. Participants currently include the Medical
College of Wisconsin in Milwaukee; Roswell Park Cancer Institute in
Buffalo, N.Y. and Instituto de Oncologia Pediatrica, in Sao Paulo,
Brazil. Rush-Presbyterian-St. Luke's Medical Center in Chicago;
University of Illinois Medical Center in Chicago; Hospital Sirio
Libanes in Sao Paulo Brazil; and Hadassah University Medical Center in
Jerusalem, Israel have also asked to join the multi-center study.
In the first clinical study, the team examined each patient's mouth,
tongue and throat. They asked the patient to rate the current level of
pain before treatment. Each patient received one minute of LED therapy
starting the day of the bone marrow transplant and a one-minute
treatment each day thereafter for a two-week period.
The treatment device was a 3-by-5-inch portable, flat array of
light-emitting diodes. It was held on the outside of a patient's left
cheek for just over a minute each day. The process was repeated over
the patient's right cheek, but with foil placed between the LED array
and the patient to provide a sham treatment for comparison. There
wasn't any treatment of the throat area, which provided the control for
the first study.
The researchers compared the percentage of patients with ulcerative
oral mucositis to historical epidemiological controls. Just 53 percent
of the treated patients in the bone marrow transplant group developed
mucositis, considerably less than the usual rate of 70-90 percent.
Patients also reported pain reduction in their mouths when compared to
untreated pain seven days following bone marrow transplant.
Quantum Devices of Barneveld, Wis., makes the wound-healing LED device.
The company specializes in the manufacture of silicon photodiodes —
semiconductor devices used for light detection — and light emitting
diodes for commercial, industrial and medical applications.
