1. High color temperature, light blue
It looks more handsome. K is a mark of k number, and the color temperature of general halogen lamps is less than 3,000. Xenon lamps usually start at 4500k. 7000k is very common. Two days ago, I saw a partner saying there was a 12000k Xenon lamp. This is crazy, and sure blue is purple. The K value is very high, usually closer to daylight and easier to accept, but I think the real benefit of high color temperature is just good looking, and other things are not very useful.
2. High brightness
Please note that color temperature and brightness are fundamentally different concepts. Neon lights are not due to high color temperature, but because of high brightness. The unit of brightness is lumens. The lumens of xenon lamps are generally three times that of ordinary halogen lamps.
3. Low energy consumption and long life
Low energy consumption, long life and other aspects have little to do with us.
