Is there a big difference in performance between LED bulbs?


LED bulbs are known as eco-friendly products because they save energy and reduce carbon emissions because they are more efficient than general lighting.

As a result of testing 12 products with high consumer preference by the Korea Consumer Agency, there was a difference of up to 1.6 times between the products in terms of the speed of light, that is, brightness alone.

The brightest lighting was found to be the Homeplus signature product.

There was also a difference of up to 1.6 times between products in terms of luminous efficiency, meaning the brightness of light per power consumption.

In addition, there is an evaluation item called 'flicker', which indicates flickering of light. Exposure to severe light with flicker can increase eye fatigue and cause headaches.

Most of the lifespan performance was excellent, but only Lumian products that received KS certification were found to be unsuitable for the standard.


There is a difference of up to 1.6 times in terms of light efficiency.

You explained this, but by changing to a product with high light efficiency, you can save a lot of electricity and protect the environment?


That's right.

Consumers tested and found that replacing the least luminous and high-efficiency bulbs can save up to 39% energy.

The product with the highest light efficiency was 131lm/w.

The low one dropped to 80lm/w.

Assuming 2 hours of use per day, if you replace these two bulbs, the annual power consumption per bulb will be reduced by 5kWh.

Annual carbon emissions are reduced by 2.1 kg.

Even if 22 million households across the country change only one light under this condition, it is calculated that the annual energy consumption will be reduced by 110 GWh, saving 17.6 billion won in energy costs per year.

110GWh is equivalent to 26,000 households with four people for one year.

In addition, carbon emissions were reduced by 47 kt per year.
