that is not fiber optic lamps
no material is made of fiber optics.
that is just plastic strings cut up in same length and stick them with glued in one end to create flower effect then added color bulb in the bottom to make the light effect at the other end of the plastic stick.
i don't mean to crap, but that thing is crap. the technology is used 4-5 years ago for decorations in events (disney, local parades). it's so cheap, it shouldn't cost more than 3 - 4 bucks.
moreover, claiming that it's fiber optic that's just plain lame way to do business.
buyer beware!
