When choosing lighting, the choice of light source is crucial, which directly affects our visual experience and quality of life. Common light sources include incandescent lamps, fluorescent lamps, energy-saving lamps, and LED lamps.

Incandescent lamps, once the workhorses of home lighting, emit light by heating filaments with electric current. However, its energy consumption is surprisingly high, a large amount of electrical energy is converted into heat energy and wasted, and the lifespan is relatively short, generally only about 1000 hours. Although its light is relatively warm and soft, considering today’s pursuit of energy conservation and environmental protection, it has gradually been eliminated by the market.

Fluorescent lamps use mercury vapor discharge to generate ultraviolet rays and stimulate phosphor to glow. It is more energy efficient than incandescent lamps and can emit a variety of colors. However, fluorescent lamps have strobe problems, and eyes are prone to fatigue and may even cause damage to vision under this light for a long time. In addition, fluorescent lamps contain harmful substances such as mercury, which can cause pollution to the environment if not disposed of properly after disposal.

Energy-saving lamps, also known as compact fluorescent lamps, combine the advantages of fluorescent lamps and incandescent lamps, the light efficiency is much higher than that of incandescent lamps, and the life is relatively long, up to 8000 – 10000 hours, which can save energy and costs to a certain extent. However, it also has the problem of strobe and mercury.

In contrast, LED lights have become the most popular light source at the moment. It is a solid-state semiconductor device that emits energy through the compounding of electrons and holes. The energy consumption of LED lamps is extremely low, and the power consumption is only about one-tenth of that of incandescent lamps at the same brightness, which has a significant energy-saving effect. However, the lifespan is extremely long, reaching more than 50,000 hours, reducing the hassle and cost of frequent lamp replacement. Moreover, the LED light has almost no strobe and has a high color rendering index, which can more realistically restore the color of the object, which is very friendly to the eyes. It can also easily implement dimming and color grading functions to meet the lighting needs in different scenarios.

When choosing LED lights, pay attention to some details as well. It is necessary to pay attention to the brand and quality of lamp beads, which are more guaranteed in terms of luminous efficiency, stability and longevity. For example, lamp beads from brands such as CREE and OSRAM are highly recognized. At the same time, to check the relevant parameters of the lamp, such as the color rendering index (Ra), try to choose products greater than 80 Ra, for places with high requirements for color reproduction, such as photography studios, art exhibition halls, etc., you should choose LED lights with Ra greater than 90.

The choice of light source is the core of lighting selection, and LED lamps have become the best choice of lighting sources in modern life with their many advantages such as energy saving, longevity, and eye protection. When choosing, we must consider all factors and choose the most suitable light source for ourselves, so that bright and comfortable light can illuminate our lives.
