I’ve had a query about LED strips and individual LED lights. Both have their place.

I want to buy a light hat:

If you are thinking of investing hundreds of dollars into a commercial transcranial red and near infrared light device, make sure that you select a device made with individual LED lights.

Their interest was piqued by reports that photobiomodulation can help lower blood glucose levels in people with diabetes. Blood glucose levels stay high in diabetes and that causes all sorts of problems for the rest of the body.
