In view of the various questions raised by our customers, we have summarized 10 key issues and provided corresponding answers. These issues focus on core points such as the causes of LED light flickering, the standardized procedures for installation and replacement, and compatibility adaptation, aiming to offer you precise and instructive references.
Q1:What causes the flickering of LED lights?
A： LED light flickering is often caused by poor-quality driver power supplies. These inferior driver power supplies are unable to provide a stable current, resulting in the lights flickering unsteadily. To solve this problem, the key is to choose LED lights that adopt a constant-current driving solution. Constant-current driving can ensure a stable current output and effectively eliminate the flickering phenomenon.
Q2: Can I install the commercial freezer light by myself? Is it convenient to replace it?
A: Since the installation process involves electrical circuit safety, to ensure operational safety and avoid safety accidents caused by electrical issues, it is recommended to have a professional electrician handle the installation. However, when it comes to product replacement, we have provided a complete set of installation accessories. You only need to easily remove the old light from the bracket and replace it with the new one, making the whole process convenient and hassle-free.
Q3: Can your refrigerated display light replace Philips lighting fixtures?
A: The LBS series lighting fixtures from Laidishine are capable of being interchanged with Philips lighting fixtures. If you have a replacement need, this series is a good choice.
Q4: How long can your freezer lights last?
A: Our lighting fixtures have undergone rigorous testing and are expected to have a lifespan of up to 50,000 hours, during which their brightness will only decrease to 70% of the initial level. Assuming you use them for 12 hours a day, the expected lifespan of the fixtures is over 10 years. Even after more than 10 years, the lights will still maintain 70% of their original brightness. However, it’s important to note that high-power light strips must be equipped with heat sinks to achieve the expected lifespan.
Q5: Are your lighting fixtures low-voltage or high-voltage ones?
A: Our lighting fixtures include both low-voltage and high-voltage types. Among them, the high-voltage fixtures are typically in the T8 style and are relatively more affordable, while the rest are low-voltage fixtures. The low-voltage fixtures feature an external driver design, demonstrating excellent stability.
Q6: What are the “pseudo-energy-saving” pitfalls that customers often misunderstand?
A: When selecting lighting fixtures, be vigilant against the following “pseudo-energy-saving” pitfalls hidden behind marketing rhetoric:
Super bright = energy-saving: Lighting fixtures with high brightness but low luminous efficacy (lm/W) may actually consume more electricity.
Low-priced LEDs: These often use inferior chips that result in rapid light decay, with brightness dropping by 50% within one year.
Neglecting heat dissipation design: Lighting fixtures that generate excessive heat will have a shortened lifespan, indirectly increasing replacement costs.
Q7: How to prioritize lighting fixture selection based on different scenarios?
A: Different scenarios have varying priorities for lighting fixtures, and decisions can be made based on core objectives and budget:
| Scenario Type | Recommended Priority | Key Indicators |
| Convenience Store/Community Supermarket | Energy Efficiency First | Focus on energy consumption, lifespan, and intelligent dimming capabilities to reduce operational costs and achieve energy-efficient lighting. |
| High-end Boutique Supermarket | Display Effect First | Emphasize Color Rendering Index (CRI), color temperature consistency, and anti-glare design to highlight product display effects and create a high-quality shopping environment. |
| Cold Chain Storage Center | Energy Efficiency First | Select lighting fixtures with low heat generation and an IP68 waterproof rating to meet the special environmental requirements of cold chain storage and reduce energy consumption. |
| Cooked Food/Bakery Counter | Balanced Type | Require a CRI ≥ 90 and adjustable color temperature functionality (2700K – 5000K) to accurately present food colors while creating a warm and inviting atmosphere. |
Q8: Why does a freezer light require a heat dissipation design?
A: Although LED lights generate relatively low heat, in special environments like freezers, where there is a significant temperature difference between the inside and outside, condensation can easily form on the light body. Therefore, a special heat dissipation structure is needed to ensure the normal operation of the lighting fixture and extend its lifespan.
Q9: Have your products obtained UL certification?
The vast majority of our products have passed UL certification, which means you can A: confidently install and use these LED lights in commercial settings, industrial applications, and home environments. Laidishine offers UL-certified LED light strips to ensure that customers are using high-quality components.
10:There are so many product series on your website. How should I choose?
A: Our website features a diverse range of product series, typically categorized into economy, Premium, and Standard models. These products all utilize lens technology and have similar luminous efficacy, but differ in materials and appearance. If you’re feeling overwhelmed by the choices, our sales experts will recommend the most suitable product based on your specific needs.
