Q:How much LED 150W downlight spiral energy-saving lamp replacement

I do the lighting! First, where do you use 150W energy saving lights? With 150W energy saving lamps will only be used in industrial and mining lights, indoor general lighting is unreasonable. Simple answer to you, the general energy-saving lamp (60ml/W) lumen is led (120ml/W) half, that is, 150W energy saving, with 75W LED can replace brightness!

Q:LED lamp power off why would light up

LED lamp power off, will light up, this situation is normal in the 220 electric power supply situation, reason is caused by the distributed capacitance charge discharge line.Because the switch and the lamp is connected with 220V/50Hz AC power supply is normal, directly added to both ends of the lamp, the lamp work light; when closed, switch capacitor and lamp itself and the line is connected to the alternating current of 220V/50Hz, because the distributed capacitance of the charge and discharge can form weak current, the lamp will light.Solution: in the lamp circuit board input end in parallel with a pressure resistance of at least 400V of non-polar capacitor, capacity 0.05 micro method above (if the switch connection is longer, can be appropriately increased).

Q:LED is not only the benefits of downlight what harm?

The characteristics of LED lamp: overall unified and perfect to keep building decoration, without destroying the lamps installed, building decoration light hidden inside, the light source is not exposed, no glare, the visual effect is soft and uniformThe advantages of LED downlight:1, energy saving: white light LED energy consumption is only incandescent lamp 1/10, energy-saving lamps 2/5, longevity: LED theoretical life can be more than 100 thousand hours, for ordinary family lighting can be described as "once and for all"". LED downlight pictures (19)2, can work in a high-speed state: energy-saving lamps, if frequent start or turn off, the filament will blacken, quickly damaged.3, solid state package, belong to cold light source type. Therefore, it is easy to transport and install, can be installed in any micro and closed equipment, not afraid of vibration, the main consideration is the heat dissipation.4, LED lighting technology is changing rapidly, and its luminous efficiency is amazing breakthrough, the price is constantly decreasing. The era of a white LED lamp coming into the home is fast coming.5, environmental protection, without mercury (Hg) and other harmful substances to the environment, will not cause damage to the environment. The assembly parts of LED lights can be easily disassembled and disassembled, and can be recycled by other people without recycling by the manufacturer. LED does not contain infrared and ultraviolet light, so it does not attract insects.6 、 fast response speed: LED fast response, completely eliminates the shortcomings of the traditional high voltage sodium lamp glow process.To say LED downlight drawback is the market disruption of LED products are not up to the specified standard, so the market will have a lot of defects, and the price is low

Q:LED downlight downlight and how to distinguish?

The lampshade can be made exactly the same. Distinguish between LED and ordinary lamp can see the inside of the light source, is a common lamp installation of energy-saving lamps. It is an LED light source lamp
