I'm not certain about the claims but can say I love mine for the type of light it gives off. It has a dimmer switch which is essential. I would describe the light like that of a campfire but no flickers or smoke 😀 just a soft warm light that is enough to see by but never blinding. Blue light (screens, tv, overcast day...) is a trigger for me and the quality of light is important. I have these really ugly amber glasses for watching tv or a movie, and have a color changing bulb for the back room. It has an app you can control the bulb with, no need for a special lamp or get out of bed. I like red when my eyes are unhappy, they just seem to relax a little more. Maybe Fromm good memories of photography and dark rooms 😀 I found the bulb on Amazon, salt lamp and glasses, too. There's a free program you can download for laptops that is called flux and it will adjust your computer screen to remove blue light. It's good for everyone to help wind down end of day. The newer iPads and iPhones now have a setting for this blue light stuff, too.
That's way more than you asked for but I got on a roll (it was a good reminder for me too!)
Whoops, that replied on the wrong spot, sorry 😀
