Q:Why can't the voice switch control the time of the LED bulb?

The production lights can be controlled. Where do they go to consult?

Q:LED bulb with what type of LED beads?

Of course, the more high-end heat better use EMC3030 lamp, EMC2835 lamp and so on, please consult your supplier

Q:Where can LED bulb be used?

The surface of the lamp body is sprayed with high quality heat radiation paint, that is, the heat dissipation efficiency is ensured, and the appearance is elegant, and the utility model provides better guarantee for the low temperature work of the product.

Q:LED can the bulb be used in the bathroom?

of couse Yes, but LED kitchen and toilet light is recommended

Q:Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?

One point price must be a sub goods, this is wrong.Plastic cheap because the cost is relatively low, can not talk about grades, plastic LED mainly for the application oriented,

Q:Will the power of the LED bulb grow longer and longer? Why?

The LED bulb does not become more powerful for extended periods of time.

Q:How to choose the bulb power?

If the public is not high, the quality requirements, and to control the price, you can choose non isolated, because it does not require isolation transformer, so the cost is relatively low, but the aluminum substrate voltage requirements is relatively high, otherwise there may be charged radiator, and still light outside is not very beautiful.

Q:What's the reason why LED bulb gets a lot of heat?

If the radiator is about the same size, it's not nice to touch the low temperature, because the heat accumulates in it and doesn't come out. The.LED lamp doesn't last long

Q:What does "A19" mean in LED A19 bulb?

A represents the bubble type, A hemisphere bubble 19, and the back figure indicates the bubble size (mm in diameter)

Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!

If it is to continue the glimmer of minutes, the main side is the use of resistance and step-down circuit caused by the normal phenomenon. It's very rare for the factory to use this old model to make LED balls. Circuits that run for hours or all day on the side of the LED bubble are out of order. It's not normal to shine for so long. Now most of the LED bulb is using IC constant current supply circuit, no such situation has emerged.
