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

As far as I know, high power fluorescent lamp and compact fluorescent lamps use is unsafe, even no relevant national standard, if you use it, the auspicious light test report please check the product certification and CCC what, if there is a problem with the best replacement as soon as possible.

Q:How to judge the quality of LED downlight

Determine the quality of LED ceiling lamp lighting effect, the United States and Taiwan LED chip chip chip, domestic chip etc.. Different brands, different prices, lighting difference is also large. Special low price downlight, make many use of chip production line down the defective products, color inconsistencies, brightness difference, short service life, users need to pay attention to.

Q:Why use LED lamp light source patch

In a large number of automated production, the packaging cost of the patch LED itself and the cost of soldering to the circuit board are lower than those of the small power LED.

Q:How to choose the right LED downlight

Look at the power supply lamp (commonly known as: transformer) transformer quality also determines the whole life of the lamp, lamp used more than 50000 hours no problem, but if the transformer is destroyed, the whole lamp will not light up. The electronic components and design scheme in the transformer determine the efficiency, power factor, stability, temperature rise and service life of the transformer. Our driver is wide voltage drive, and the output current and voltage are stable.

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:Turn off the lights after the bright LED lamp

Of course are,,In addition, a lamp, and if it is warm white downlight, 7W interval of 1.8 to 2 meters with a 9 watt meter interval, 2 to 2.5 meters in 1, because of the warm white Led light dark light.. If the daylight color (white) led lamp, high point to spacing of 7W or 9W, every 2 meters to 3 meters with a, above two, today I am in the company installed, the effect is very good, very bright, with a larger spacing proposal, after all Led lamp is more expensive, to avoid wasting the resources that can help you save a lot of money, today I am in the company installed 12.8 meters long * 7.45 meters wide, more than 90 square, 1.8 meters vertical spacing and horizontal spacing of 2 meters with a 9 watt Led lamp with fifteen Led lamp, brightness is bright, do not feel the need so, if you are one hundred square pavement, a lamp should be 20I hope I can help you.

Q:Now there is no replacement of the LED light source lamp?

Yes, it depends on what level you want. I can solve your problem with a net name.

Q:What brand of downlight is good? Please explain the reason, thank you!

Cost. From a cost perspective, the LED lamp price is about 3-10 times of the traditional lighting range, if the power of the time more than 6 hours a day, LED lighting is good, is expected about 1 years to be able to save money to buy a lamp; if one day 2-3 hours, it is not how much electricity the.

Q:What is the difference between the LED and the LED lamp ceiling lamp

The main difference is in appearance. As Shenzhen City Shengda photoelectric Co. Ltd is specialized in LED indoor lighting products such as LED ceiling lamp, LED lamp, they are the series of the two products to the ceiling. Their use is virtually the same.

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
