I love this light in many ways. However, I bought it primarily for its dawn simulation function, as it boasts a gradual wake up. Studies emphasize the need for a gradual wake up, and MagicLEDLightv2 lets you set it for a gradual wake up. In reality, it turns on very very quickly. I set it to gradually wake me up over the course of an hour, yet it actually brightens fully within a minute or two. So, that is false advertising. I not only spent money on the light bulb, but also on a fixture that I could hang over my bed. I thought I was saving money because a gradual dawn simulator is typically expensive. Now I have to start all over again.
