In our daily life, we all use a variety of lamps and light sources, such as incandescent lamps, energy-saving lamps, and LED lamps. They can be used for direct lighting or as light sources for lanterns.

Incandescent lamps are the electric light source closest to natural light. Their color temperature is usually between 2700K and 4000K, which is easier for the human eye to accept. Therefore, the advantage of incandescent lamps is good color rendering, but the disadvantages are power consumption, low photoelectric conversion efficiency, and short life.

Energy-saving lamps, or CFLs, are a variant of fluorescent lamps. The advantage is that it can be made into any color temperature value, has high color rendering and low flicker value. The disadvantage is that the fluorescent tubes of energy-saving lamps are filled with mercury vapor, and the environmental protection issues in manufacturing and recycling have not yet been well solved.

LED lamp sources have very high light efficiency. Its advantages are small size, no flicker, no UV, and high light efficiency. Usually the color rendering of LED products will exceed 80, and some can even reach 95. Moreover, LED lamps have a long service life. The disadvantage is that the current market price is relatively high, and the country has not yet specified clear standards for it.

Regular lamps and lanterns are the light sources that we often use in our daily lives. Each has its own advantages and disadvantages, and there is no absolute good or bad. However, when purchasing, we must choose lamps produced by manufacturers and brands.
