Q:Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!
Plastic bulb lamp, I have done it myself, this gadget specializes in low-end market, it is recommended not to use, used well, used for a long time, used poorly, minutes of effort have to hang.
Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
4 and three is different. An incandescent lamp relies on heating the electrode wire to send out visible light. The energy-saving lamp releases the electrons by conducting the electrode wire, while the LED light is led by the diode.
Q:LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?
The cost is too high, the latter is better than the former, with long service life, there is a need bulb welcome to Taobao fry and sales of professional manufacturers of high power LED lighting lamp.
Q:What is the 15 Watt lumen of the LED bulb?
Each brand has different bulb qualities, probably around 1W between 60-85LM/W.
Q:What does the LED bulb patch mean?
The patch is referring to the lamp is put up, refers to the non patch lamp is plugged in, the distinction is probably a stick is inserted.
Q:I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
Or if there's a problem with the process, just zoom in and see!
Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?
A LED lamp lumens general good point value is above 100;The brightness of 60W incandescent lamp compares with LED lamp difference is 10 times;
Q:Will the power of the LED bulb grow longer and longer? Why?
Voltage problems, as well as unstable factors.Long time no change, should
Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem
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?
The LED price of aluminum alloy 3W is probably about 30.
