Clarity - 40Hz Light Bulb by Gamma - Improve Brain Function & Memory - Entrainment Device Biothm 40Hz Light Therapy Bulb Gamma Flickering LED Lamp, 9W White E26/E27, Holder Included Review: Works as Intended, Useful for Gamma brain wave entrainment - 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. ## Features - 40Hz Gamma Light Therapy - Clinical research shows that 40Hz light frequency may help support cognitive health, memory, and focus.

There are some rather expensive gadgets out there exploiting this technology. This is a cost-effective method for experimenting with 40 Hz gamma entrainment, or perhaps treating someone that may need this for therapy(?) It's just an LED light bulb with some clever electronics built in. Easy to set up (desk lamp?), easy to use. Inexpensive. From my own reading on the subject, a 40 Hz RED light might be even more useful(?)
