It creates a corona, and lights up the two included fluorescent bulbs as well as a neon tube light within 1 to 1

Do not buy this if you don't know how to solder well, or at least have someone clean up your mess and re-solder everything so you don't have shorts on the transistor pins, don't have cold solderjoints, and don't overheat the parts while soldering

Overall a great kit if you have some soldering experience, and it took only about 15 minutes to assemble
