A source of hope and help for families battling cognitive decline.

Bought the light for my mom who is 73 and has experienced cognitive decline. I let her know about the importance of the light, and we did some research about 40 hz. To see her reaction when I was reading the articles to her made me smile. She uses them every morning and she seems to be sleeping better and feeling better.

I’ve noticed my mom is becoming more forgetful, so I purchased the lights for her. She feels like it’s working for her. To me, my mom seems less confused and more alert so I’m feeling better too.


I purchased the first version of this product a few months ago and experienced great results at home. Better sleep and better focus. I got the new light to have in my office and this one looks and works great.

My own experiences with the tragedy of Alzheimer’s disease in my late husband Ed Epstein, prepared me well for facing disappointments about “cures” or even therapies that work for cognitive impairment or dementia. I feel differently about Beacon40 by BRIGHT. Not only is this a promising and non-invasive way to help your brain stay alert and attuned, Beacon40 cheers you with its light.

I am a psychiatrist. I do a lot of work in, what I call, cognitive enhancement, or optimization. Some of it is the prevention of heritable cognitive issues, such as Alzheimer’s. I got the first generation Beacon40 for my mom and aunt. They've been using the lights for a while now, and cognitively they have not declined! For 2 years! It's so encouraging to see what Beacon40 is providing for my family... More time.

My wife was diagnosed with Early Onset Alzheimer's three years ago. While her symptoms are still comparitively minor to most, her moods can be pretty awful with frequent anger issues and awful verbal fighting, starting out first thing in the mornings. Since the first day of using Beacon40, there was a dramatic shift. She loves having it on next to her in our living room while watching TV. She began counting down the days that we had not had an argument and is acutely aware of its benefits. She is simply happier. This is not a paid review or something made up. Beacon40 works.
