Both posters make good points, I don't have the expertise to judge the quality of the trials but I though some of the thyroid trials were interesting, likewise the macular degeneration ones (I was researching macular degeneration for a friend, when I came across this page).
Here's an interview with Dr Hamblin (who has a WONDERFUL accent!) but it's two years old. It would be interesting if a more recent interview became available, given the increase in trials at the moment:https://www.youtube.com/watch?v=wAW8Fvg-TJQ

I got a 830nm lamp but haven't consistently used it, as I haven't been able to find a strong, flexible enough stand to hold it in place (the lamp weighs 270gr and 13cm across the front. I have noticed that when I did use it a lot in the evening that my sleep became quite disturbed and that response was quite consistent. So I now usually use it in the mornings and that seems to work out fine. So it does have some effect but I'd need to be more consistent wrt a specific complaint.
Considering the amounts of various supplements I'm shovelling into myself without much to show for it right now, this device seems cheap and at worst harmless!
