LED bulbs, would you choose?

Have you moved a lot since March 15? Although there is no LED on the party nothing, but as the guy used to illuminate every day, the old rookie can not help but ask a question, will you really choose LED bulbs? Teach you a lamp magic, the spell is like this: “old rookie, cute!” Learn this mantra and you will learn the magic of choosing LED bulbs. Back to the book, the following is the old rookie lamp training lecture time:

Is it difficult to choose LED brands and products on the market? Old rookie teach you a “class of two listen to three see”, learn this method, choose the lamp not worry! Teach the old rookie before many words, a few dollars of LED bulbs or do not choose, this thing installed at home and installed a time bomb is the same as the same!

A phase modulation

Class, is class weight. In the same wattage, almost the same shape material, size of the case, of course, choose the heavier one!

2 listen to

Turn on the LED bulb and listen to it with your ear close. Don’t choose those with obvious “buzzing” sound.

Three see

This “look” is divided into four steps: packaging, parameters, appearance, lighting.

① Look at the packaging, there is no energy grade mark on the packaging box resolutely do not choose. Don’t know what an energy rating label is? It doesn’t matter, Duang look at the picture:

Photo: This is the energy rating label, which indicates that the bulb is rated A and can be purchased. A is the most energy efficient, G is the least energy efficient.

Figure: There is no energy grade mark on this package. Do not buy such products.

② Look at the parameters. There are many parameters, aren’t there? We don’t know who’s who, do we? In fact, we do not need to see so much, just look at the light flux, the same power under the circumstances, choose the higher value of LED bulbs. Biāng, Biā mg, Biāng, Bi ǎng~ Look at the picture

Picture: 4W LED bulb, of course, choose the one of 300 LM.

Public service advertisement: see no energy grade identification on the packaging box, printed “save electricity 90%”, can report oh, the quality supervision bureau will punish him 50 thousand oh! The bad guys, are they starting to shiver?

(3) Look at the appearance, the lamp loose do not choose, the interface position loose do not choose, the appearance of rough do not choose.

Photo: don’t show off such rough workmanship and advise you not to choose it.

(4) look at the light, the light after such points to see, stroboscopic, uniform, light color, color.

What about stroboscopic? Cell phone cameras can initially identify severe stroboscopic. Strict determination requires a stroboscope.

What about uniformity? In fact, just look at the bubble, without further ado, duang duang, look at the picture!

Figure: the uniformity of the light source is good, consistent up and down, no obvious difference between light and dark.

Photo: Look at the “bubble” of this bulb, too much variation from top to bottom, poor light guide material

What about light color? It is the white light, warm light, yellow light that we often talk about. Here is mainly about white LED bulbs, if you see the faint blue, green, do not choose. Although there is no need to talk about blue change, but the faint blue light on your eye fatigue, children’s eyesight…… More or less.

Photo: The 5700K bulb is already emitting blue light. In addition, the above two mentioned stroboscope, uniformity, it all accounted for the waterfall sweat…… Do not choose such products.

How to look at the color? Please stretch out your palm and check your palm under this lamp ~ the ruddy skin color that looks normal is a good bulb, and the “sick color” that looks green is far away from you!

From this picture, you should know which light bulb to choose, right?
