Q:The office, sample room, corridor, the most commonly used several LED downlight which is several dimensions, what is power?
Big ones. 6 inches. Our company is using this big one.
Q:Turn off the lights after the bright LED lamp
Because the electrician is working on the power off switch, the power switch is a zero line, not a live wire. Electricians know that the power switch must be cut off by the line of fire, and no danger of electric shock is announced. If the power switch is on fire line, after the power is cut off, the FireWire will continue to supply power to the LED driver. Therefore, the LED lamp will have a faint light when the switch is turned off.
Q:Excuse me, how many different sizes for LED lamp lumens
See customer needs and in what place, with the output of the LM itself and quality of reflective glass beads, beads arranged, there is a direct relationship between the transparent mask
Q:Home LED lighting downlight is broken, want to change themselves, I would like to ask how to remove ah? Where do you start?
This figure is LED lamp, with the outer edge of hand buckle lamp can be removed from the back lamp, and the lamp can be damaged when installing a new launch, as long as the lamp cup cup (two pin plug back) directly inserted into the can.
Q:The difference between ordinary LED lamp and LED downlight and integration of advantages and disadvantages
Integrated downlight features:1. strong anti glare than the old lamp;The 2. lamp body adopts integrated design;3. spring elasticity is more suitable for installation;4. new package 2835 beads, can provide high lumen output. Have completed the best quality lamp wafer chip package can provide high brightness output. In many applications, it is very suitable. The design is compatible with the element size, brightness and trust so as to make the design more uniform spot downlight;5. the design of fastener design and opening recognition has been increased in packaging, which improves the reliability of packaging and the convenience of installing holes.
Q:What is the size LED downlight
The inches here are inches, not ancient measurements, inches, feet, rulers, etc.. 1 inches =25.4 mm =2.54 cm (1 inch = 2.54cm)So:4 inches =4 X 2.54=10.16cm. About 10cm = 100mm6 inches =6 X 2.54=15.24cm. About 15cm = 150mm8 inches =8 X 2.54=20.32cm. About 20cm = 200mm
Q:Led downlight and LED flat lamp that is durable
This is not comparable. The simplest thing is to see which lights have CCC certification, so that at least in quality will be better.
Q:LED is not only the benefits of downlight what harm?
Not good manufacturers can only be said to be defective, LED competition in the domestic market is too large, resulting in product quality, now there LED manufacturers can LED lamps prices do with energy-saving lamps are almost the same, I smiled, this is the difference
Q:How many good color family LED downlight
It depends on personal preference, but there are some samples
Q:How are LED lamp quality is good or bad?
Drive power. A good driving power can guarantee a whole lamp life, theory of life LED lamp is 100 thousand hours, and the driving power of general life ranging from less than 50 thousand hours. So in order to ensure the whole lamp life, LED lamp manufacturers tell you that the driving power is very important, and it is also one of the most critical components. On the other hand LED downlight must be a constant current power supply, if using constant voltage power supply low cost will greatly shorten the service life of LED lamp. Then, how can we identify the constant current power supply? You can see several parameters, service life, light, light effect and warranty period. If the service life is longer, the quality of the power supply will be relatively better.
