NorbSMILE Full Spectrum Light Bulb - Sunlike Premium A19 9W Wellness LED. Boosts Energy & Mood, Supports Circadian Rhythm, High Color Rendering, Imitates Sunlight Indoors, Energy Compliant (1-Pack)

These are great! Very vibrant. I don’t have a lot of natural light at my home so these really help make up for that. I have both the bright and warm variations and I love them both.

Hate this time of year as it gets dark so early. This replaces “sunlight” and repels SAD. Seasonal Affective Disorder.

I have introduced many people to buy this light bulb. Most of the items sent to Taiwan recently are. I suggest that this bulb can be divided into 5000K and 5400K. And can launch enhanced 700nm spectrum to be better and more complete. such as a picture. Because after all, the vast majority of lighting soft panels are yellowish. I looked at the picture and thought it was a 5400K but I received a 5000K. but i still like them. and it's on top of me. Although the bulb is a bit yellowish for my lighting. light bulb is very very good. he can really relax. and has very good color reproduction. Make people feel stable. recommended purchase. I will buy more in the future. Will continue to recommend to friends.

Light works ok, could be brighter.

It is helping me recover from SAD . This is only the third day of sun in a long time. I am using it to recover from three months of overcast weather with no sunlight.

These look very bright but they don't offend the senses the way some lights do. I don't know how much they actually affect my sleep rhythm since there are a lot of factors that go into why I sleep early daily but keeping them on past 6pm does make it easier for me to stay up and finish whatever I'm doing before I decide to go to bed. Coincidence? Not sure. I like them though.

Light emitted mimics daylight on the gray day; that is, not warm.

I purchased two bulbs and I do like the product, but one quit working after 3 months. And it won’t be replaced because it’s over 30 days since I purchased.
