No way, he is talking about the temperature of the plasma itself not the color. If the color temperature was 6600 in that demo the thing would have been yellow looking. There are 4 states of matter: solid, liquid, gas, and plasma. Plasma only occurs when a gas is heated to extreme temperatures. From Howstuffworks.com:
"If you boost a gas to extremely high temperatures, you get plasma. The energy begins to break apart the gas molecules, and the atoms begin to split. Normal atoms are made up of protons and neutrons in the nucleus (see How Atoms Work), surrounded by a cloud of electrons. In plasma, the electrons separate from the nucleus. Once the energy of heat releases the electrons from the atom, the electrons begin to move around quickly. The electrons are negatively charged, and they leave behind their positively charged nuclei. These positively charged nuclei are known as ions.
When the fast-moving electrons collide with other electrons and ions, they release vast amounts of energy. This energy is what gives plasma its unique status and unbelievable cutting power."
That quote is about a plasma cutter that heats gas to 17,000k to cut through metal like its butter, while the lighting company isnt cutting anything, they arent going as hot either. But if its a PLASMA based light, it is definitely heating some type of gas up to some crazy temperature to produce the reaction....probably 6600K.
