Modern people pay attention to the CP value when buying goods, and hope that the goods they buy can be used for a long time, are cheap, and easy to operate. Light bulbs are the most frequently replaced consumables at home. I often worry about replacing light bulbs. I don’t know which brand to buy. I get a defective product with the wrong specification. I bought it but I can’t install it when I return home. I bought it and changed it and bought it again, now follow our step by step, let us teach you how to choose!

Step 1: lamp holder

The first step in choosing a bulb is definitely to confirm the specifications of the lamp holder. The most common specifications of LED lights on the market are roughly “E12”, “E14”, and “E27”. The most commonly used lamp holder in general households is the E27 bulb. The most common, as the name implies, “E14” is 14mm in diameter and “E27” is 27mm in diameter. Usually, there is a mark on the package. If the package has been discarded, the diameter can be measured directly.

Step 2: Save power

The most important thing to use a light bulb is to save electricity. Take into account environmental protection and purse. You can choose to have an energy-saving label. In addition, you can judge by the “wattage”. The lower the wattage, the less power consumption. First, confirm how many lumens of light bulbs you need, And then choose the lamp with the smallest wattage, that’s right! If you can’t find the lumens, you can look at the luminous efficiency (LM/W). The luminous efficiency multiplied by the wattage is the lumens.

Step 3: Brightness

“The larger the wattage, the brighter it is” is the blind spot of consumers. Wattage refers to the power consumption of the bulb. Whether it is bright or not depends on the number of lumens. The higher the lumens, the brighter the bulb, and vice versa.

Step 4: Low frequency flash

Low-frequency flicker is often overlooked by many people, because sometimes it is a high-frequency flicker that cannot be noticed by the naked eye, such as office light bulbs…etc. In the long run, it will not only damage the eyes but also increase fatigue and discomfort. The bulb can increase learning and work efficiency, and then meet the needs of “eye protection”. When choosing, you can pay attention to whether there are words such as low-frequency flash on the package.

Step 5: Safety certification

The most important thing is to buy with peace of mind, especially if you have the elderly and young children at home, you need to pay more attention to buying light bulbs. You must choose a light bulb certified by the Bureau of Energy of the Ministry of Economic Affairs of Taiwan: BSMI certification, peace of mind and guarantee!

Is it still foggy after watching it? It doesn’t matter. The above problems can be solved with BLTC frozen bulbs. The frozen bulbs exceed the standards of “Taiwan Ministry of Economic Affairs Bureau of Energy: BSMI Certification” and have energy-saving labels to ensure energy-saving and environmental protection. Compared with other brands, the same light bulb is brighter under the wattage, and the warranty is up to five years!
