Strobe effect bulbs

I have been trying many E11 LED lights and this LED has been brighter than the others but no way close to a 100W halogen. The problem I have is they flicker at a rate that is not visible but have a strobe effect. the water in the sink flows funny, the ultrasonic brush looks like it moves real slow. It does give a headache after some time. It is not dimmable. The lakes version of the bulb seems to be the overall best performer for dimming, brightness and flicker free.
