Hello everyone, I bought some LED bulbs online some time ago, and they just arrived today. Then I sent three free of charge. It’s very cheap. I’ll show you today.
There is an LED bulb that is a good comment on defense for a dollar. It’s equivalent to spending only one yuan for three free shipping, which is a good deal. Before, I bought one in the physical store, and it cost me nine yuan. Let’s try this today and see how it is. First, take it apart and see how it works inside. Press it. This should be the glue inside, just press it.
The structure of LED bulbs is quite simple. A rectifier bridge, a chip, and this is a lamp bead. 11 lights. The structure is very simple. Take a look inside. Not even that raw meat slice. The transformer and the filter capacitor are all gone. It’s very simple. Like this, er, there is no heat sink, and it’s easy to get hot and burn. This one is not durable. It won’t last long. Let’s try it. How about its brightness?This is written in ten watts. It may not actually be achieved. Try the brightness. It’s still bright. Why does his light flicker? Its workmanship is relatively poor, that is, we can’t see it directly with our eyes, that is, when we turn on the camera, we can see it when we take a picture. It keeps flashing.
Does my nine-yuan LED bulbs have a long life? Let’s take a look at this. If you live a long life, it’s not good for your eyes. See? This one is not blinking. Like this, the quality is better. We can’t see it directly with our eyes. We have to turn on the camera to see if there is any flicker. If the LED bulbs flicker, it will be very bad for the eyes if they are used for a long time.
Have you seen it? I’ve been enjoying it, but it’s a good deal for one yuan. Don’t ask too much. Today’s content is shared here. Friends who like my content should pay attention to it. Thank you for watching.
