Energy-saving lamps for restaurants. KFC used to use ordinary fluorescent lamps, but later some stores switched to energy-saving lamps. No matter fluorescent lamp or energy-saving lamp, there are many kinds of light colors to choose from. If you choose a warm bulb (tube), the effect will be warmer. Nowadays, the more fashionable energy-saving lamps have a color temperature of more than 5000K, which is similar to sunshine. They are available in shopping malls and are slightly more expensive.

It should be noted that the effect of photos and visual effects are often not exactly the same, and photography also has digital processing factors, which is not easy to compare.
