Surprisingly Unknown? Four Disadvantages of LED Lighting

オネスト オネスト
First, please read the related link: 【Highlight】6 Benefits of LED Lighting Beyond Energy Savings, and then read this. This time, I will introduce the disadvantages. 1. High Purchase Cost For companies, switching to LED in many areas of the facility can lead to significant initial costs. However, as explained in the total cost section, it is possible to recover these costs in a short period due to reduced replacement frequency and lower electricity bills. 2. Sensitive to Heat A disadvantage of LED lighting is its sensitivity to heat. Caution is needed when using it in high-temperature areas such as bathrooms. 3. Heavy Weight LED lighting includes circuits and other components in addition to the emitting part, making it heavier compared to fluorescent and incandescent bulbs. Therefore, care must be taken regarding the installation strength of lighting fixtures like chandeliers. 4. Cannot Emit Light Uniformly While fluorescent lights emit light uniformly in a 360° manner, LEDs cannot emit light uniformly, resulting in varying brightness depending on the location, which is also a disadvantage. Despite these disadvantages, it is essential to promote the switch to LED due to its energy-saving effects and other benefits.

Energy-saving LED lighting that can be used anywhere.

High-spec ballast-free light bulb with no noise and flicker-free.

Flicker refers to the "flickering" of a light source that is flashing at an invisible speed. Displays and LEDs may appear to be continuously lit, but in reality, they are flickering at a high frequency that is not visible to the human eye. Even at such an imperceptible flicker speed, cameras capturing a moment or recording video can capture this flicker, resulting in dark photos or flickering images. Additionally, since they do not continuously flow current, power consumption is reduced, leading to lower electricity costs and longer LED lifespan. 【Features】 ■ Waterproof and dustproof with IP65 rating ■ Flame retardant with a slow burning speed, and scorch marks can be easily wiped off with a dry cloth ■ The LED chip is made by "Epistar," a major manufacturer that has a cross-licensing agreement with the Japanese manufacturer Toyoda Gosei.

Risa Yoshiki has been appointed as the official ambassador of b-search Co., Ltd.!

  • NEW
  • COMPANY

On July 1, 2026 (Wednesday), talent Risa Yoshiki has been appointed as the official ambassador of b-search Co., Ltd. We are pleased to announce the appointment of Risa Yoshiki, who is active in various fields such as television and magazines, as our official ambassador (effective July 1, 2026). With this ambassador appointment, we at b-search Co., Ltd. aim to deliver the best recruitment solutions to many companies struggling with hiring activities, while also strongly promoting the joy of taking on challenges in work and the appeal of new ways of working to job seekers considering career changes or employment. ■ Background of the official ambassador appointment In today's world, where the declining labor force due to low birth rates and an aging population is advancing, "acquiring and retaining talent" has become an extremely important management issue that affects corporate growth. What is required in future recruitment activities is not the traditional method of "simply posting job advertisements and waiting for applications." What is urgently needed now is "proactive recruitment," which involves partnering with companies as their "best No. 2" to consistently promote everything from the planning of recruitment strategies to the establishment of systems that yield results.
