Йӱла T8 морозильник волгалтарыше-влак тошто улыт мо?

Пост иктешлымаш: T8 fluorescent tubes have left a significant mark on the industry, both in the past and present. But with the changing times, are T8 fluorescent tubes still suitable for the current industry situation? I conducted a survey...

Шукерте, I started a simple poll on LinkedIn about whether traditional T8 fluorescent tubes are outdated, and the results surprised me:

Are Traditional T8 Freezer Lights Outdated

As shown in the figure, 42% of people chose “Depends on application”. Why did this happen? I believe there are several reasons:

Икымше, this indicates that many people in the refrigerated display case industry still have a certain level of knowledge about fluorescent tubes, even possessing considerable expertise. They don’t completely reject older technologies but rather view them with a critical eye. Among the clients I’ve encountered, whether retail stores or refrigerated display case manufacturers, some still insist on purchasing our T8 fluorescent tubes. Most of these clients use them for replacement projects. This is largely because they don’t want to change their existing wiring and connection methods. Ала деч посна, replacing high-voltage tubes with low-voltage tubes requires a separate power supply for the low-voltage tubes; тугеже, considering cost, many clients still choose to purchase T8 tubes for replacement, and the replacement cost is lower than the installation cost. In terms of luminous efficacy, T8 tubes can achieve 130-160 лм/В, meeting the needs of many customers who prioritize brightness.

Comparison Of Different Connectors For T8 Fluorescent Tubes

Кокымшо, the refrigerated display lighting industry does indeed experience rapid product iteration. In the tide of time, some products have gradually been phased out. In conventional understanding, the market is no longer suitable for vigorously promoting traditional T8 fluorescent tubes because, compared to 24VDC LED tubes, нуно:

Кугу энергийым кучылтмаш. At the same illuminance, LEDs use 30%-70% less energy and generate less heat. Freezers operate 24 суткаште 20 шагат, and the heat generated by the lights is ultimately dissipated by the freezer’s compressor. Тугеже, T8 fluorescent tubes not only consume more electricity but also increase the load on the refrigeration system, resulting in double energy consumption.
Low light utilization. For T8 fluorescent tubes, since there are no human modifications, the tubes emit light in 360°, and the direction of the light cannot be controlled. Лектыш, a large amount of light shines on door frames, cabinet tops, or the ground instead of the merchandise, leading to a significant waste of light.
T8 fluorescent tubes rely on high-frequency ballasts, often resulting in flickering that, while not noticeable to the naked eye, is clearly visible under a mobile phone camera lens. With more and more consumers taking photos and videos to share on social media, this flickering can negatively impact the visual experience.
Low color rendering index. Most T8 lamps use LEDs with a CRI of 70-80, which results in low vibrancy and color rendering of products under the lamps, especially meat and vegetables, which may appear stale to buyers under low CRI lighting.
In terms of safety, T8 lamps are typically AC110V or AC220V. If the lamps malfunction during business hours, there is a risk of electric shock to shoppers.

Бирок, even though T8 fluorescent tubes are considered “obsolete” in a modern sense, many manufacturers continue to produce them, hoping to quickly replace them when customers need replacements. Ала деч посна, thanks to technological innovation, current T8 fluorescent tubes are no longer traditional. Мут, previously, when T8 fluorescent tubes were installed in freezers, most tubes experienced problems due to condensation entering the freezer, leading to numerous after-sales issues and increased costs. To improve this, Radison and Carrier collaborated to upgrade the connectors for T8 fluorescent tubes, changing from the traditional G13 socket to a direct wiring outlet, and upgrading the waterproof rating of the T8 fluorescent tubes from IP20 to IP67. In subsequent developments, the wiring harness connectors have also undergone several design changes to meet the requirements of different freezer manufacturers.

This shows that as long as there is market demand, even products considered obsolete by most people will gradually upgrade through technological innovation. Products change according to market demand, and it’s impossible to eliminate T8 fluorescent tubes in the short term. Бирок, with increasing global emphasis on environmental protection and energy conservation, more and more countries are advocating the use of energy-saving products. Many countries are tightening import and export controls on T8 fluorescent tubes, and the threshold for obtaining certification is becoming higher. Тугеже, this has given LED lights an opportunity for rapid development, as low-voltage LED lights have significant advantages in efficiency, лӱдыкшыдымылык, да волгыдо пайдалыкше. I think this is why 47% of people believe that T8 fluorescent tubes are obsolete. I will analyze this option further later. From my perspective, I would also recommend that customers choose the most suitable lighting products for their freezers based on their actual needs.
