Q:How are LED lamp quality is good or bad?

Light source. Professional manufacturer of LED downlight tells you that the power quality LED lamp generally adopts imported Samsung point light source. Light source is chosen well, its lamp quality is bad also not where to go.

Q:Led downlight can light panel directly with intelligent dimming Mody?

The lights can only be switched on, because the way LED works is different from ordinary incandescent lamps, and dimming panels designed for incandescent lamps cannot hold LED. If you are using the lamp holder and driving split LED light, you can choose an output voltage, current, the same, to support dimming drive to replace the original driver, in order to achieve dimming

Q:How to judge the quality of LED downlight

A good LED downlight, design not only to see it the radiator, but also its driver, the core part will have to see it with the chip, which is what we call the LED lamp.

Q:7 square feet of aisle to install 3 LED downlight, how much w led downlight

You need to know how bright it is to be sure

Q:LED lamp power off why would light up

LED lights turn off the light: 1, the switch is cut off the zero line, you can change the line.2, share change in induction. Switch off zero line with switch.No electricity and no effect on the light, so ignore it.

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:How many good color family LED downlight

Personally feel about 3500K color temperature appears soft and warm. I hope it works for you

Q:LED downlight downlight and how to distinguish?

LED lamp is composed of a group of LED lamp lines, each lamp line required voltage is very low, so it is necessary for certain circuit can directly used in 220V lighting circuit, the original quality of the circuit in the decision LED lamp life, general service life is several times more than ordinary lamp, price is high, energy saving and environmental protection. Is the direction of development, is to use the ordinary lamp bulb, is the most simple incandescent lamp, low voltage lamp with transformer can access 220V power.

Q:The opening 7, 5 cm height of the LED lamp, home decoration into the floor with fear of hydrochlorothiazide

The average height is around 45mm-60mm. If your space height is greater than 60mm, you don't have to worry.

Q:Led downlight and LED flat lamp that is durable

The same power cases are led lights, the length of life depends on his cooling conditions, the better the heat dissipation, and its life is relatively longer
