Q: LED how does the bulb return electricity?: What is reflow? Never heard of it. I am a lighting technician

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: 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 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: 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. The bathroom is suggested by the power supply lamp, lamp waterproof plate etc..

Q: How to identify Ic constant current LED bulb?: Look at the power supply, there are a few simple electronic and capacitive circuit board, it is not constant flow, cross flow is larger, so understand? Cross flow IC, that is, the meaning of intelligent voltage regulator, so that the LED is not easy, bad capacitor driven LED is relatively easy to damage, easily breakdown, and power consumption than the cross flow

Q: What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!: Sandblasting can be transparent, light is not dazzling,But will still see the light...

Q: Are there any differences between negative ion bulb and LED bulb?: Negative ions should belong to traditional lighting technology, LED is the latest lighting technology

Q: What advantages does LED bulb replace energy saving lamp?: The LED lamp is solid-state lighting, if all LED lamps a year remaining nearly three electric power Three Gorges hydropower station, the country.

Q: What brand of LED bulb is good in quality?: Look at the bulb of the bulb. The so-called bubble shell refers to the transparent glass shell in front. In incandescent lamps, all are made of glass. But in LED bulbs, though they can be made of glass, they rarely do.. Because the LED bulb weight than incandescent lamp 5 times or more, if made of glass, fell on the ground, it broke the possibility of large. As a result, more LED bulbs are made of plastic to prevent them from breaking. And the LED bulb went out because the heat from the radiator, so the bulb Everbright is visible light, infrared heating has little, so the use of plastic to make foam shell will not damage due to heat.
