Understand the two parameters, LED lamp purchase is not offensive

After the second phase of electricity price increase in Taiwan in October, although the price was slightly reduced due to the non-summer electricity price, in order to avoid increasing expenses in the future, the average household electricity consumption should be controlled within 500 degrees per month. The electric lamp that will be turned on every day must be started, but it is an effective method.


Compared with traditional bulbs, LED bulbs can save a lot of electricity costs, but the product details to pay attention to when buying LED bulbs are not different from traditional halogen bulbs. Brightness, color, and energy efficiency must be considered before they can be replaced at home. After LED bulb, it can save power, eyes and feel comfortable.


The higher the lumen tile value, the better the energy efficiency


· Lumen value → brightness, the higher the value, the brighter the lighting


When choosing LED bulbs, pay attention to the "lumen value" and "K value", the lumen value represents the brightness, the higher the value, the brighter the lighting. As for the wattage of the light bulb, it is power consumption, so the power saving efficiency of the LED light bulb can be judged by the brightness that can be emitted per watt. The higher the "lumen tile" value, the better the energy efficiency.


· K value → namely the color temperature, the higher the K value, the whiter the light


Another "K value" is commonly known as color temperature. The higher the K value, the lighter the color of the light is to white. The white light used in the home living room is usually 5000K to 6500K, and the soft yellow light suitable for the bedroom is about 3000K.


It is worth noting that the LED bulb is designed with "half-peripheral light" that is divided into half-ball exposed and shiny, and the other half is the lamp holder, and the "full-peripheral light" is only covered by one third of the lamp holder. The "half-peripheral" lighting angle is small, suitable for people who avoid too dazzling indoors; while the "full-peripheral" lighting angle is wider. People can visually inspect the translucent shell of the LED bulb to make it thinner and relatively dazzling.


When purchasing LED fluorescent tubes, the matters needing attention are also the same as LED bulbs. The industry reminds that although LED fluorescent tubes can be used to remove the starting gas of traditional fluorescent lamp holders and directly install them, LEDs are suitable for direct current. The traditional lamp holder circuit is Alternating current, it is recommended that the public invite professional technicians to reconnect the cable at home.
