bios-Nightfall A19 Experience

Ever since I received my initial pack of Nightfall bulbs my wife and I have been amazed at the positive benefits we have experienced.
I was a little skeptical at first regarding the Companies’s claims regarding the technology and the health benefits, but now my wife and I are definitely enthusiastic believers
We have used the Nightfall A-19 bulb for a month now and noticed a positive difference in our quality of sleep already. I believe it works exceptionally well and I am thankful to find such an innovative company with this proven NASA technology. I have recommended This technology to not only my friends and family but to Industry associates to possibly get involved with this exciting and innovative company.

Night and Day

The difference in the light quality compared to the Costco downlights is like night and day. I had lasik done several years ago and with that I had more sensitivity to light. I'm not sure if its the high R9 value or what but my eyes have been less "strained" compared to traditional LED. I chose to write the review under this product because it's perfect bedside lamp to help calm the kids down before bedtime.
