"Helping my mood and day time sleepiness in only a few hours."
I have only been using this bulb for a couple of hours and I already feel more alert because of the bright light. As someone who is affected by short day time hours in winter, I'm already seeing the benefits!
Some people mentioned that they noticed a flicker on the bulb. I noticed this too but but then adjusted the rotation of the bulb where it clips into the light fixing by 180 degrees and this seemed to sort it out. So might be something to do with the bayonet connection to your fixing, maybe give this a go.
There is something about the slightly blue light that makes me feel more awake. It is very bright.
