With eleven red envelopes, just buy the LED bubble, try the first time, you can light up, to confirm receipt. See the white transparent plastic, the heart is always not assured, take a look at it. This is the brand of LED bulb.

This product is very difficult to screw down, is the screw on the mouth of the glue, with an alcohol lamp heating, hard to twist, only to unscrew the aluminum heat.

Take a look at the transparent glue like melt, flow out of the way. Really scary, but also glad to open in time, or dangerous.

Pull off the film and try it with fire.

Meet the fire immediately, did not see the melt, it seems that the specific heat of the melt. But this thing is not fire, there are hidden dangers.

Constant current chip.

This glue is strong enough, it's hard to get out of it. Be careful with the calculations, installation.

This kind of advantage is summarized, constant current drive, double gold beads, heat is thick. The disadvantage is combined with the lamp cooling is not good, I pressed the welding. Screw thin, can break, I really admire. The lampshade is warm and white. Fixed with glue, the glue will burn in the face of danger.
