Q: The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb: The light produced by the three is different. From the lighting point of view, incandescent light can generally emit yellow light, and energy-saving lamps can not only send yellow light, but also white light, etc., and LED lights can be issued according to the needs of a variety of light, decorative lighting is very good.

Q: LED what kinds of screw bulbs are there?: Ordinary bulb is the most common, is a metal electrode which is threaded, so it requires that one electrode when installing the socket contact thread to pick the zero line, the middle dot electrode lamp power. Otherwise, an electric shock occurs when an accidental contact with the exposed metal. Because of this symmetrical way, the bulb can be threaded to fit the socket.

Q: How does the LED bulb go with the power?: voltage range as long as the 36V can be achieved, for example: voltage range 24v-80v is very good,

Q: LED can the bulb be used in the bathroom?: Ordinary bulbs can be used in the bathroom, the bath water, protection grade ordinary bulb is not high, it is easy to make when water vapor lamps or rust element short circuit failure and cause some accidents.

Economy: as a result of electricity saving, electricity costs can be reduced, and the cost of the lamps can be recovered for one and a half years. A family can save tens of thousands of yuan a month. Low carbon: saving electricity is equivalent to reducing carbon emissions. Long life: LED lamp life of 50 thousand hours, six hours a day, that is, 20 years of life. The price depends on how many watts you need, and the price varies with the wattage. Now the family uses "lightning man" led, very good, the price, quality, those are good, you can go and see. Hope to help you.

Q: Is there any flicker in the LED bulb?: Really, the voltage in our home is likely to lead to fluctuations in the LED bulb strobe in public, voltage instability will be more common, but most of the voltage is relatively stable, does not appear large fluctuations, so the strobe is not violent, but the fact is there.
