Cheapo LED strips that are dimmable tend to flicker. That's how they control the overall brightness - by switching on and off rapidly. Many fluorescent light sources also flicker. Your eyes can't see the flickering, but your camera sure will unless you use a longer exposure time ("slow shutter speed").
Cheap LED lights also have parts of the visible spectrum missing from the light they output. This makes getting accurate colors of your products difficult.
If you want to blow the background out to white, you need to make sure the background is lit by a light source brighter than what is illuminating your subject.
There are lots of existing questions here at Photography SE that cover all of this.
