Great bulb. Fits into most lamps and are nice to have for the darker seasons.

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.

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.

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.

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.
