You need these! Stop spiking your cortisol!
Buy these! Do it!! We are slowly updating all our light bulbs to these. We did our bedrooms first and now are doing the living spaces. We all tell a hugeeeee difference since using these bulbs!! I am not tired and wired at night and fall asleep faster. I also know it is helping my kids get deeper sleep. Everyone needs these! Blue light and flickering from lighting causes the nervous system to be out of alignment (aka anxiety) and spikes cortisol (cortisol should fall at night not spike). I also love the 3 different settings! We use day and night!

50% fail rate after three hours use
First I’ll say that I love the idea of these lights, and I’m happy with the brightness and quality of the lights when installed. Using the later day and evening settings these lights will not be as bright as what one is usually accustomed to but that is part of the reason for using them. White and blue light is not the only thing which affects circadian rhythms, the brightness of light does also, so the dimmer output is a design feature.After installing the lights I thought I might have seen a little bit of flicker. That was just temporary, but reading other reviews I see that flicker is a real problem. I was not using the bulbs with dimmers, and even then I noticed some flicker. These are advertised as flicker free, and avoiding LEDs with flicker is almost as important of a concern as avoiding blue light at night, and for some people flicker is an even greater problem than blue light. So that’s a major fail right out of the box.The second fail here is that of the two bulbs I installed last night and used for about three hours I discovered that one no longer worked upon turning the lights back on in the morning. Wiggling the light in the fixture it briefly illuminated, so I changed out lights to figure out whether the problem was with the Bulb or the fixture. Swapping fixtures and swapping bulbs it’s clear that the problem is with the bulb. So 50% fail rate after about three hours of use is another indication of really poor quality control.So the bulbs are not flicker free, and they are of very poor quality. I’m not going to take a chance that the evening setting of the bulbs is actually free of blue light. This was my first experience with this company’s product and will probably be my last with them. While I have no idea whether competitive products from some of the higher end companies will be of any greater quality than these are I certainly can’t trust that this company’s lightbulbs are going to be worth the premium paid for them.

Unreliable Quality but Good Idea
Flicker-free! But other than that… Meh. The color tones just don’t feel amazing. Most importantly one of the bulbs started dying for hours at a time and then turning back on 3 months after purchase. I switched it to another socket and same issue. I would therefore look for another brand next time. I love the idea to switch colors, and turning the light on and off to switch is genius and works great.
