Q:LED bulb w can replace 40W incandescent lamp

I am engaged in the LED drive industry, not very professional, and I hope to help you.About brightness and energy saving comparison,1W LED=3W CFL (energy saving lamp) =15W incandescent lamp3W LED=8W CFL (energy saving lamp) =25W incandescent lamp4W LED=11W CFL (energy saving lamp) =40W incandescent lamp8W LED=15W CFL (energy saving lamp) =75W incandescent lamp12W LED=20W CFL (energy saving lamp) =100W incandescent lampBecause the company uses the light quality is not a reason, so this is not absolute.

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

This should be the power problem. It's easy to make a noise because there are so many parts of the power supply.

Q:Can the bulb's true life reach 30000~50000 by LED?

LED bulb is a new type of energy saving lamp to replace traditional incandescent bulb. The traditional incandescent lamp (lamp) of high energy consumption, short service life, in the global resource environment, has been gradually by governments to ban the production, instead is the product of electronic energy-saving lamp, electronic energy-saving lamp while improving the energy saving effect, but because of heavy metals using a lot of pollution of the environment, trend against the environment protection. With the rapid development of LED technology, LED lighting has gradually become the best choice for new green lighting. LED is far superior to traditional lighting products in light emitting principle, energy saving and environmental protection

Q:How does the LED bulb go with the power?

Generally we use the LED lights, 1W, 2W, 3W, 12W, and so on, the factory has been set in advance, directly connected to the 220 volt power supply can be, and do not need to be so complicated.

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:What's the difference between a glass cap for a bulb and a PC hood?

ProcessabilityMachinable, blister, special-shaped processing PC easier.

Q:Detailed description of LED bulb lamp

A bulb is composed of seven parts, which are at the top of the glass cover is stuck on the base, the base will be above the hole, the base is connected with the heat conducting seat, heat conduction seat is connected with the radiator, connected with the lamp holder is the driving power, light is lamp.

Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb

5, the three have different service life. The service life of incandescent lamp is in 1000 hours or so, the service life of energy-saving lamp is in 6000-8000 hours, and the service life of LED lamp can reach more than 30 thousand hours.

Q:LED what does "A60" mean by bulb 60? And what does "MR16" mean?

60: diameter 60mm (metric unit) MR16: diameter is 16*1/8*25.4mm (Imperial units), although refers to the diameter, but the height and other dimensions are also prescribed

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

The meter usually doesn't turn because the current is too small to drive the meter (Mechanical), of course, the electronic meter also depends on the sensitivity. I don't think so. At least I used to do LED (light power about 0.5W it) is equivalent to 3W incandescent lamp brightness around. The meter does not rotate when it is shining normally.
