Information
Out of all the noble gases, Neon glows the brightest in a vacuum discharge tube when the atoms are excited by an electric current. This is why it is a popular choice for neon-tube lights.

Joseph's Element Collection
Joseph received this plasma lamp, which contains neon gas and sends electric currents through to give the impression of lightning inside the lamp, as a Christmas present in 5th grade. Joseph actually thinks that the color looks more like Argon than Neon, but until further information is obtained we will leave this sample here.
