When choosing a freezer, although internal lighting is not a core consideration, it does affect the user experience. When you open the freezer, if the light is dim or not at all, looking for something becomes a "treasure hunt in the dark". Not to mention the trouble, you may also miss the ingredients hidden in the corner, resulting in expired waste. What kind of lights do you use in the freezer? Let's have a good chat.
LED lights: the current mainstream choice
LED lamps now account for most of the freezer lighting field. From an energy-saving perspective, it is simply a "power-saving expert". When traditional lamps emit light, a large amount of electrical energy is converted into useless heat energy, while LED lamps have a high power conversion rate. Under the same brightness, the energy consumption is much lower than that of traditional lamps. Take the common 10-watt LED freezer lamp as an example, it only consumes 1 kWh of electricity after 100 hours of continuous operation, which can save a lot of electricity in the long run for a freezer that runs 24 hours a day.
In terms of lifespan, the average lifespan of LED lamps can reach more than 50,000 hours. After calculating the bill, assuming that the freezer is turned on for 5 hours a day, the LED lamp can last for about 27 years, which is almost the same as the lifespan of the freezer itself. This greatly reduces the frequency of replacing bulbs, saving worry and effort.
Moreover, the cold resistance of LED lamps is unparalleled. The internal temperature of the freezer is often minus ten or even tens of degrees. Under this low temperature, the filament of ordinary lamps is easy to become brittle and broken, or it is difficult to start. LED lamps are not affected. Whether it is in the cold winter in the north or the freezer's ultra-low temperature freezer, they can light up instantly and emit light stably, ensuring that you can see every item in the freezer at any time. In addition, LED lamps are highly safe, free of harmful substances such as mercury, and will not generate too much heat to affect the cooling effect of the freezer. Its light color rendering index is high, which can accurately restore the true color of the ingredients, allowing you to judge the freshness of the food at a glance. In terms of color temperature selection, the common cold white color temperature (6500K - 7000K and above) can create a refreshing and clean visual experience, which complements the refrigeration atmosphere of the freezer.
However, LED lamps also have a small drawback, that is, the upfront purchase cost is slightly higher than that of ordinary lamps. However, the advantages of comprehensive energy saving and long life are very cost-effective from the perspective of long-term use. It is widely used in various household and commercial freezers, fresh freezers in supermarkets, refrigerated display cabinets in convenience stores, and horizontal and vertical freezers in households.
First, fluorescent lamps: once the "darling", now the supporting role
Before the popularity of LED lamps, fluorescent lamps were a common choice for freezer lighting. Their luminous efficiency was higher than that of traditional incandescent lamps, which were relatively energy-saving and could meet basic lighting needs. In the freezers of some large supermarkets, fluorescent lamps used to be seen, and their bright light could illuminate all corners of the freezer, making it convenient for customers to choose goods.
But the disadvantages of fluorescent lamps are also obvious. First, its lamp tube is fragile, and it is easily damaged once it is collided during the frequent opening and closing of the freezer and the handling process, which increases the maintenance cost. Second, the brightness of fluorescent lamps is insufficient when starting, and it takes a few seconds to ten seconds to reach normal brightness, which is really inconvenient when it is urgent to pick up items. Moreover, fluorescent lamps contain harmful substances such as mercury, which can cause pollution to the environment if they are not properly disposed of after being discarded. Nowadays, with the rise of better LED lamps, the application of fluorescent lamps in the field of freezer lighting has gradually decreased, and it can only be seen occasionally in some commercial or household freezers that do not require high stability of lamps and pursue certain energy-saving effects and brightness.
Second, incandescent lamps: simple and cheap, but gradually being phased out
Incandescent lamps can be said to be the most traditional lamps. They are affordable, and in some small grocery stores and temporary freezers, in order to control costs, incandescent lamps may be selected as lighting. It has good color rendering, can truthfully show the original color of the object, and the starting speed is a must, that is, turn on and light up.
However, the shortcomings of incandescent lamps are also doomed to decline in freezer lighting. It is extremely power-hungry, a large amount of electricity is wasted on heating, energy efficiency is extremely low, and long-term use of electricity is expensive. At the same time, its lifespan is short, usually only a few hundred to a thousand hours, and frequent replacement of light bulbs is not only troublesome, but also increases the cost of use. In low temperature environments, incandescent lamp filaments become brittle and the risk of breakage is greatly increased. Therefore, except for some special scenarios that are extremely sensitive to cost and not used frequently, incandescent lamps have been rarely used in freezer lighting.
In general, LED lamps are the best choice for freezer lighting today due to their many advantages such as energy saving, long life, and cold resistance. But different scenarios have different needs. If the budget is limited and the frequency of use is low, incandescent or fluorescent lamps can also be used as a temporary transition. Understanding the characteristics of these lamps can help you make the right choice when choosing a freezer or replacing a freezer lamp.
