no no no. kelvin is the SI unit of heat. Its conversion from degrees celcius is + 273.15. 273.15 K is equal to to the freezing point of water which occurs at zero degrees celcius. Light is energy but it is measured as a function of wavelength (lamda) and frequency (hertz). Because you are dealing with xenon gas, electrons become exicited from the heat energy and jump from their ground state into a higher orbital shell. The light you see is emitted when the electrons then lose that energy and fall back to their ground state. The color of the light emitted is due to the length of the wave which dictates it's location on the visible spectra which ranges from violet at 400 nanometers to the longest wave of red at 700 nanometers. Anything beyond that is either ultraviolet or infared. So it is all related to HEAT!
In laymans terms; 6000 kelvins hotter than 4100 kelvins higher heat = brighter light thus, 6000 hotter/brighter than 4100. Also, do you beleive everything you read on web pages? Try opening a chem book. a little factoid: there is actually a small percantage (.005%???) that dont see the waves cast by xenon disharge meaning that nothing is reflected for them. Basically, its like having the lights off for them. Sucks huh!!

The color of light is measured in degrees kelvin, but has nothing to do with energy emitted because of color temperature, nor does it have anything to do with more brightness associated with that energy increase.
Brightness is still measured in lumens, and fact is 4100K gives off 3200-3500 lumens, while 6000K gives off 2600 lumens. On HID bulbs that is. If a halogen 3200K bulb was able to put off 4000 lumens, it would be BRIGTHER than an OEM 4100K at 3200 lumens, and we would have much greater vision at night. It would also put off tremendous amounts of heat and would consume tremendous amounts of power. If the ultinon 6000K bulb was able to produce the 3200-3500 lumens of the OEM 4100K at its color temperature, we wouild probably be able to see better under most road conditions since its color temperature is closer to bright noon daylight. OEM uses 4100K because it is "the best bang for the buck". More lumens for less watts, period. |
