After I had a query about the effectiveness of LED lights versus laser lights, I wrote a blog post here on the Well Red website.
As noted in the article by Vladimir Heiskanen and Michael Hamblin, the use of lasers is more related to the history of laser development rather than lasers being intrinsically better than other light sources.
In summary, stick with LED lights. They are safe to use and don’t have the health concerns that come with lasers.

Light Ahead Inc aims to help people to learn about neurogenerative diseases and the practical, safe and scientifically-based things that may be able to help. Part of this is to provide low-cost access to red light devices, hence the DIY instructions on this blog. All sales of the Coronet red light device support the work of Light Ahead Inc.
