‘LED Bulb’ Comparative Information Generation Results – Ministries Briefing | Briefing Room | news

There is a difference in the quality of LED bulbs, such as light efficiency, flashing, and lifetime performance, and when using high efficiency products, energy savings of up to 39% have been found compared to low efficiency products.

LED bulbs, which are more efficient than general lighting and have a longer lifespan, are establishing themselves as environmentally friendly green products due to their energy saving and carbon emission reducing effects.

Accordingly, as a result of testing and evaluating the main performance of 12 LED bulbs with high consumer preference by the Korea Consumer Agency, there is a difference in core performance such as light efficiency, flashing, and lifespan of each product. It was necessary to choose.

Please refer to pages 6 and 7 of the press release for detailed test products, test items, and methods.

Here are the results of major tests and evaluations for LED bulbs.

In terms of light efficiency, both products were relatively ‘excellent’, and energy savings of up to 39% were possible when using high efficiency products.

The light efficiency, which shows light brightness per power consumption, was relatively ‘excellent’ for both products.

Both Homeplus Signature and GE products were found to be ‘excellent’ with a relatively high light efficiency of 130lm/W or more.

Both products, Lumian and Onreprice, were rated ‘normal’ with a relatively low luminous efficiency of 89lm/W or less.

As a result of comparing the energy saving effect of replacing a low efficiency product with a high efficiency product, it was found that approximately 39% of energy can be saved per LED bulb.

When it was expanded to all households in Korea, the annual power consumption was 110GWh, and the annual energy cost was about KRW 17.6 billion and the annual carbon emission was reduced by 47 kt.

Brightness varied between 877 and 1,461lm per product, with Homeplus Signature products being the brightest.

The color rendering performance was good for all products, and there was a difference of up to 1.3 times for each product in the directivity angle.

When using a light bulb, the color rendering index, which shows how similar the color of an object is to natural light, was 83~86 for each product, with little difference, and all were at a good level.

As a result of checking the orientation angle to check how wide the light spreads, there was a difference of up to 1.3 times between the products, and the Homeplus Signature product had the widest lighting range at 201 °.

There was a big difference between the products at Flickr, and both products were relatively ‘excellent’.

As a result of evaluating the quality of the tremor, which checks the degree of tremor, there was a big difference between the products, and both products were relatively ‘excellent’.

Two products, OSRAM and Philips, were evaluated as ‘excellent’ with significantly less flicker.

On the other hand, the four products, No Brand, Lumian, Bungbang Pyo, and Onreprice, were rated ‘normal’ due to their relatively large tremor.

In terms of lifetime performance, most of the products were evaluated as ‘excellent’.

As a result of evaluating the lifetime performance according to the brightness maintenance ratio after lighting for 2,000 hours compared to the initial brightness, most of the products were relatively ‘excellent’.

On the other hand, it was found that Lumian products that have received KS certification do not comply with Korean industrial standards. The company replied that the measures to improve life performance had been completed.

Energy efficiency and safety ratings were all good.

As a result of checking compliance with the stated energy use efficiency rating and the risk of electric shock through dielectric strength and insulation resistance tests, there were no abnormalities in all products.

In terms of labelling, 5 products did not meet the relevant standards.

As a result of checking the labeling of each product, it was found that five products, Namyoung LED, ONLYPrice, Longevity Lamp, Lumian, and Dooyoung Lighting, did not meet the relevant standards.

Among these companies, four companies, including Lumian, Dooyoung Lighting, Lotte Shopping, and Woori Lighting, have completed or responded to plans to improve display.

In addition, when purchasing LED bulbs, consumers needed to select an appropriate product for their intended use by considering the product performance and price of the purchase and selection guide on page 4 of the press release and the comprehensive result table.

The Korea Consumer Agency will continue to provide safety and quality comparison information on highly efficient and environmentally friendly home appliances to support consumers’ reasonable use.
