Lights play an important role in the retail at night since retail lights not only illuminate the display shelf but also create a special phenomenon either active or warm. That have the magic ability to motivate people’s mood which is the key factor to attract the walkers getting into the stores or shops. But how to choose the right retail display light would be a big challenge for the merchants since matching lights with different color temperature and colors is difficult. But today we are going to introduce how to choose types of lights only.

Incandescent lamp

Until now, the most widely used incandescent lamp in the world has always been the electric bulb. When it glows slightly, it can give people a soft, warm and emotional feeling. These light bulbs have different wattage and different shapes and sizes, but the production cost is not very high, and the selling price is usually not high. These bulbs are commonly used in desk lamps, floor lamps or chandeliers. However, 90% of the energy consumption of incandescent lamps is usually thermal energy instead of photosensitive energy, and this ratio will become higher only after being used for more than 2,000 hours.

Halogen lamp

Halogen bulb is abbreviated as halogen lamp, also known as Shi Ying bulb, which is a variant of incandescent lamp. The principle is to inject halogen gas such as iodine or bromine into the bulb. At high temperature, the sublimated tungsten wire reacts with halogen chemically, and the cooled tungsten will re-solidify on the tungsten wire to form a balanced cycle to avoid premature fracture of the tungsten wire. Therefore, halogen bulbs live longer than incandescent bulbs. The luminous principle of halogen lamp is very similar to that of ordinary incandescent lamp. The tungsten wire of halogen lamp has a higher melting point than that of ordinary incandescent lamp, so the brightness of halogen lamp is greater than that of incandescent lamp, and the energy consumption is reduced by about one third. Halogen lamp power supply voltage is usually divided into AC 220V and DC 12V and 24V. Halogen lamps are usually used in places where centralized illumination is needed, headlights and rear lights of automobiles, as well as public places such as homes, offices and office buildings.

Advantages

1. As far as ordinary incandescent lamps are concerned, halogen lamps have higher efficiency and good color rendering

1. The tungsten filament of halogen lamp has a higher melting point than that of ordinary incandescent lamp, so the brightness of halogen lamp is greater than that of incandescent lamp

1. Good color rendering (Ra=100)

Disadvantages

1. Halogen lamps should not be turned on/off frequently, otherwise their service life will be obviously shortened

1. Halogen lamps are more expensive to buy and use, and will generate more heat.

1. The working temperature of halogen bulbs is very high, so you can turn on the headlights and remove the bulbs only after the bulbs are fully cooled.

Fluorescent lamp

Fluorescent tubes are once again leading the way when we start looking for more energy-efficient lighting methods. Both fluorescent bulbs and fluorescent tubes have low consumption and high output. When they are used indoors, only 30% will be converted into heat energy, which is lower in temperature and consumes less energy than incandescent lamps. Fluorescent tubes can use additional devices to adjust the light, and dimmable fluorescent bulbs have also appeared in the market.

Advantages

1. Equivalent to ordinary incandescent lamps, energy-saving lamps can save 80% of energy consumption.

1. They have a longer life, and can usually be used for 10,000 ~ 20,000 hours according to different models and manufacturers.

Disadvantages

1. Lack of light adjustment function

1. Fluorescent bulbs contain mercury, which cannot be discarded at will and must be sent to relevant departments for recycling.
