Le luci a LED hanno rapidamente guadagnato popolarità nel settore dei frigoriferi commerciali grazie ai loro notevoli vantaggi, come l'alta luminosità, lunga durata, ed eccellente stabilità, gradually replacing traditional fluorescent lamps. Attualmente, T8 high-voltage and low-voltage light tubes are quite prevalent in the market, with nearly identical brightness levels, leaving many refrigerator manufacturers puzzled when making a choice. Numerous LED light manufacturers recommend opting for low-voltage lighting fixtures as a replacement for T8 lamp tubes. COSÌ, which is better, high-voltage or low-voltage? Infatti, each has its own set of pros and cons.
An Analysis of the Advantages and Disadvantages of T8 High-Voltage Light Tubes
T8 high-voltage lamp tubes have a long-established application history in the lighting field, and their relatively low purchase cost is a significant advantage. Tuttavia, it also has some drawbacks that cannot be overlooked:
High risk of electric shock
T8 high-voltage lamp tubes are directly connected to alternating current. During daily use and maintenance, improper operation can pose a potential risk of electric shock, threatening the safety of users.
Uneven brightness due to voltage attenuation
When high-voltage LED T8 light tubes are used in parallel over long distances, voltage attenuation may result in lower brightness at the end of the light strip compared to the starting end, affecting lighting uniformity. To maintain overall brightness, it may be necessary to increase power or add more lamp tubes, indirectly increasing energy consumption.
Stringent voltage resistance requirements for components
Operating in a high-voltage environment, T8 high-voltage lamp tubes impose extremely high voltage resistance and quality requirements on internal components such as PCBs, resistors, and capacitors within the light strip. The use of inferior components makes them more susceptible to breakdown under high voltage, leading to the failure of the entire light strip, thereby increasing maintenance costs and replacement frequency.

Laidishine Low-Voltage Freezer Light Series: A Perfect Integration of Safety, Efficiency, and Energy Conservation
In light of the aforementioned drawbacks of T8 high-voltage lamp tubes, Laidishine has meticulously developed and launched a low-voltage freezer light series, offering a superior choice for freezer lighting. This series comprises the LBS series, Serie SPU, SRL series, and LBF series, all of which adopt a safe low-voltage 24V design, fundamentally eliminating the risk of electric shock. Inoltre, Laidishine has spared no effort in enhancing product quality and safety. The enclosures are crafted from either PVC insulating material or aluminum alloy, ensuring both robustness and effective prevention of electrical leakage. Inoltre, we provide a 3-year warranty for our products, which boast an IP65 waterproof rating and an operating temperature range from -35℃ to +30℃. This enables them to effortlessly withstand the extreme cold inside freezers and ensure stable operation under various harsh conditions.

Low-Voltage Design, with Remarkable Energy-Saving Advantages
The Laidishine low-voltage freezer light series employs low-voltage power supply technology, representing a qualitative leap in electrical energy conversion efficiency compared to traditional high-voltage lamp tubes.
During the operation of high-voltage lamp tubes, due to their high voltage, significant energy losses occur during the transmission and conversion of current. This lost electrical energy is dissipated in the form of heat, not only resulting in energy waste but also potentially affecting the temperature stability inside the freezer.
Al contrario, the 24V low-voltage design of Laidishine’s low-voltage freezer lights ensures more stable current transmission and significantly reduces energy losses. Under the same lighting effect, these low-voltage freezer lights can operate at lower power, thereby achieving substantial energy savings. Inoltre, our entire range utilizes IC chips for constant current and voltage, ensuring uniform light efficiency.
Taking a large commercial freezer as an example, using traditional high-voltage lamp tubes may result in daily electricity consumption of several kilowatt-hours. Tuttavia, by switching to Laidishine’s low-voltage freezer lights, daily electricity consumption can be reduced by 30% A 50%. A lungo termine, this translates into significant savings on electricity bills for businesses. For commercial users pursuing energy conservation, emission reduction, and lower operating costs, this undoubtedly represents a highly attractive advantage.
Uniform Lighting, Enhancing Display Effects
The shelf lights inside freezers often suffer from the issue of glaring light, which not only affects customers’ shopping experience but may also cause certain damage to the goods. Addressing this pain point, Laidishine’s entire range of freezer lights has been developed with frosted lampshades, making the light softer and effectively avoiding glare. For upright lights, the area behind the door frame often becomes a lighting blind spot. After installing the lamps, dark areas appear behind them, resulting in uneven lighting that severely impacts the display effect of products. Laidishine’s full range of freezer lights employs advanced polarized light technology, capable of focusing the light to precisely illuminate every corner, completely eliminating dark areas. This allows the goods inside the freezer to be showcased in their best light under uniform and soft illumination, attracting customers’ Attenzione.

Installazione semplice, Meeting Diverse Needs
To facilitate customer installation and use, Laidishine has designed three different types of brackets, taking into full consideration various application scenarios. For freezer manufacturers, screw brackets are the ideal choice. They provide a secure installation, ensuring that the lamps remain firmly in place without loosening due to vibrations during freezer operation, thereby guaranteeing stable lighting. For customers with replacement needs, magnetic brackets offer tremendous convenience. Simply attach the bracket to the freezer and then directly replace the lamp, eliminating the need for cumbersome disassembly and installation processes, thus saving considerable time and effort. Rotating brackets, d'altra parte, are suitable for scenarios with specific requirements for the beam angle, especially when installing overhead lights. By using rotating brackets, the direction of the light can be flexibly adjusted to meet the display needs of different products.

Customizable Services, Highlighting Unique Charm
Laidishine understands that each customer has unique needs and therefore offers personalized customization services. Whether it’s the size, colore, energia, or parameters such as light brightness and color temperature of the lamps, we can tailor them according to customers’ specific requirements. Whether it’s the special lighting needs of large commercial freezers or the personalized designs of small household freezers, Laidishine can create the most suitable freezer light solutions for customers, ensuring that each freezer has a one-of-a-kind lighting effect.
In the field of commercial freezer lighting, the Laidishine low-voltage freezer light series has become an ideal alternative to T8 high-voltage lamp tubes, thanks to its safety, affidabilità, uniform lighting, easy installation, customizability, and significant energy-saving advantages. Choosing Laidishine means selecting a high-quality, high-performance, and energy-efficient freezer lighting solution that adds brilliance to your freezers, enhances product display effects, and contributes to commercial success.
