Q: LED thread specifications for bulb bulbs?: Commonly used thread specification: E27 screw.Commonly used household ordinary E27 spiral lamp holder;

Q: What is the 15 Watt lumen of the LED bulb?: LM, refers to a candle (CD, Candela Candela, unit of luminous intensity, the equivalent of an ordinary candle light intensity) in a solid angle corresponding to the spherical cone ball (1 square meters of the unit sphere radius of 1 meters on the representative point of view, the corresponding section in the center angle of about 65 degrees the total emission flux) on the.

Q: What are the requirements of the LED series inspection specification for bulb bulbs?: Dielectric strength: electrical endurance test (resistance test) followed by insulation resistance test. During testing, the following AC voltage is applied at the specified position 1min. Type HV (220~250V); 4000V (RMS), BV (100~120V); 2U (rated voltage) +1000v.

Q: What is the AC voltage of the LED bulb?: The LED lamp is either a constant voltage drive or a constant current drive without AC voltage. Generally through the drive circuit filter rectifier, LED bulb bulb voltage is about 10V. Add: different drive circuits, different amounts of LED chips, the final voltage is different.

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.

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.
