Q:How are LED lamp quality is good or bad?
1, in the purchase of LED lamp, can take a look at the lamp appearance, the lamp body is smooth, there is no scratches, the overall feeling is good, good LED downlight will feel heavy, because the use of the material and the radiator will be better.2, LED will take in the hand shaking force lamp, listen to whether there is noise, such as abnormal sound that no internal fixation downlight, there are security risks, for the unqualified products.3, light LED downlight, using a mobile phone camera function close to the light emitting surface to see whether there are such as flicker, flicker, the LED lamp is equipped with a power supply for the low-end products of inferior quality, affect the overall quality of LED downlight.4, the same LED lights lit up at the same time several manufacturers of the same type lamp, observe its luminous color and brightness is consistent, if not consistent is obvious, as inferior, because the same LED lamp manufacturers with the same type of products can not be light color and brightness inconsistency
Q:There are no holes 7 cm, 9W led downlight
Between general 7-12W hole 9.5 cm can be chosen, the LED lights our company own, opening 9.5 cm, 9-12W, 7W ceiling light is also your choice, to choose a bright power point, brightness not too big, choose a smaller power good enough!!
Q:How much LED 150W downlight spiral energy-saving lamp replacement
Ha ha, you need data150W energy-saving lamp with 60-70W LED mining lamp can,
Q:Led downlight can light panel directly with intelligent dimming Mody?
No, the LED dimming should be adjusted in its drive circuit
Q:How to judge the quality of LED downlight
No professional instruments, only to see the brightness drive, the size of the work chip ~!
Q:7 square feet of aisle to install 3 LED downlight, how much w led downlight
The three three watt brightness is enough, and the five watt is a bit wasted
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: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.
