Q:What are the characteristics of LED bulb?

LED bulb advantages: energy saving: the same brightness, power consumption for ordinary energy-saving lamps 1/4. Environmental protection: no harmful substances such as mercury, no pollution to the environment. (experts point out that mercury contained in a fluorescent energy-saving lamp can contaminate 180 tons of water sources). 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:LED can the bulb be used in the bathroom?

From a long-term perspective is not enough, you can choose a lamp are closed, such as ceiling lamps what, now have special indoor lamps, but you must not use ordinary lamps, because LED lights to the heat at the edge of the open slot or empty, easy water.

Q:Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!

See brightness, whether the luminous uniformity, the back of the heat is good?

Q:What's the reason for the LED bulb strobe?

In addition, electromagnetic interference (EMI) filters are also required, even in LED drive applications that provide excellent power factor correction and support TRIAC dimming. The transient current caused by the TRIAC step (step) will excite the natural resonance of the inductance and capacitance in the EMI filter.

Q:What's the cause of the noise during the aging of LED bulb bulbs?

The power supply LED bulb using miniature low power switching power supply, switching transformer due to loose, and the switching frequency did not avoid the audio area, it will beep.

Q:LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?

LED bulb: directly driven by not using AC-LED light source, light effect of the whole lamp life (compared with driving security; some) integrated LED relative heat transfer to the high requirements, high cost, simple assembly, do a single power source in low cost, high light efficiency.

Q:How did the trademark on the LED bulb go up?

Laser printing and screen printing, pad printing can be, look at the needs and equipment.

Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?

If the material with better thermal conductivity, the lamp shell about 60 degrees is best.Reason:1: if the temperature is too high, that your radiator is too small.2: if the temperature is low, indicating that your calories did not lead out. (of course, if the radiator is too large and the temperature is low, but the bulb and tube are too heavy to pass by certification)

Q:Led what's the flash of the bulb?

I don't know how you flashed this light. Did you flash or turn off the light before you left it?. If the lights are off, you should ask the electrician if the line on the switch is connected or not. If the switch is connected to the negative line, it will flash. If it is open after the flash, mostly driving power problems

Q:LED bulb bulbs, do you need 3C certification now?

No, this is a light source, not a lamp. It can only be CQC voluntary certification
