Review: It has been my experience that various 40 hz entrainment lights are not all the same. Dealing with Alzheimer's has moved me to ensure I have the very best independently tested bulbs - only two have met my standards and at decent price.

Review: I don't find the flickering light annoying. I'm not sure if it works yet. We'll see, but even if this light bulb lasts one week, I'm glad I bought it. I think there's a huge brain epidemic going on and doctors are just guessing and giving it fancy names (in my opinion, allegedly).

### ⭐⭐⭐⭐⭐ Review
*by D***R on 13 October 2021*

I wanted to get a light that flickered at 40 Hz after reading an article about brain wave entrainment. I've been using it for nearly 2 months. The bulb works as promised and expected. It flickers more noticeably than a dying fluorescent tube in a hospital morgue, but that is what it is intended to do. I don't mind the flickering, although people who are walking by when I use it remark that they find it really irritating. I don't. During the first month, I noticed that I was having very intense dreams every night, which indicated to me that my brain was reacting to it. My primary interest was to improve focus, concentration, and memory. I feel like it has helped, although it wasn't a leap to omniscience and peering through God's eye on the world. This is a good product for people who want to experiment with brain wave entrainment. I use it while listening to Gamma brain wave entrainment audio tracks. My other senses are not involved in my journey of greater mental clarity.
