12,000K HID?!?! :eek:
Anyone see these goin on ebay? Do they really burn at 12,000 Kelvin?? What color would they look like? Im not lookin to get a pair, but I cant even imagine what the color output for 12,000K would be.
Item on ebay.. Very surprising!

Degrees Kelvin has nothing to do with the amount of light or heat emitted. As a reference, an average blue sky is around 13,700 degrees Kelvin. Quick lessons:

/report mode on.
I assume these will be real Xenon bulbs right? Anyways, it will be a blue/whitish light, similar to Magnesium being burned, but substitute the mild green flames with a brilliant blue color.
History
(Gr. xenon, stranger) Discovered by Ramsay and Travers in 1898 in the residue left after evaporating liquid air components. Xenon is a member of the so-called noble or "inert" gases. It is present in the atmosphere to the extent of about one part in twenty million. Xenon is present in the Martian atmosphere to the extent of 0.08 ppm. the element is found in the gases evolved from certain mineral springs, and is commercially obtained by extraction from liquid air.
Isotopes
Natural xenon is composed of nine stable isotopes. In addition to these, 20 unstable isotopes have been characterized. Before 1962, it had generally been assumed that xenon and other noble gases were unable to form compounds. Evidence has been mounting in the past few years that xenon, as well as other members of zero valance elements, do form compounds. Among the "compounds" of xenon now reported are sodium perxenate, xenon deuterate, xenon hydrate, difluoride, tetrafluoride, and hexafluoride. Xenon trioxide, which is highly explosive, has been prepared. More than 80 xenon compounds have been made with xenon chemically bonded to fluorine and oxygen. Some xenon compounds are colored. Metallic xenon has been produced, using several hundred kilobars of pressure. Xenon in a vacuum tube produces a beautiful blue glow when excited by an electrical discharge.
Uses
The gas is used in making electron tubes, stoboscopic lamps, bactericidal lamps, and lamps used to excite ruby lasers for generating coherent light. Xenon is used in the nuclear energy field in bubble chambers, probes, and other applications where a high molecular weight is of value. The perxenates are used in analytical chemistry as oxidizing agents. 133Xe and 135Xe are produced by neutron irradiation in air cooled nuclear reactors. 133Xe has useful applications as a radioisotope. The element is available in sealed glass containers of gas at standard pressure. Xenon is not toxic, but its compounds are highly toxic because of their strong oxidizing characteristics.
HEY! It's Sunday morning and I got up at 6:00am... this explains that... err yeah.
F*cking dogs never shut up.
