Q:The same power of cob and led lamp which is brighter
LED lamp now single lamp and COB of useful products, according to the principle of the photosynthetic efficiency can distinguish under the same power that or bright.
Q:With current meter how to detect the led lamp lights, bad
Connect the battery, Ed to shoot the light, current meter, in turn, measure current value, and then put Ed lamp switch poles of the measured current value, two more obvious change is Ed to shoot the light is good, no change is bad.
Q:Excuse me, If no ceiling can hold the LED lamp?
Is two kinds of rail type with the shoot the light, you need to install a track, you will orbit is fixed at the top of the strong, and then track type lamp base card into orbit, electric rail, shoot the light will be bright

Solution is the best in qualified driving power, the phenomenon of quality control means perfect manufacturer is not allowed to the factory, the product shape will test whether design light reaction, Induction light reaction has a passive remedy is to switch the fire try zero wire transfer. Special instructions as consumers accustomed to using fluorescent tube before, induction shimmer as normal, but the LED lamp product design can eliminate this problem, the quality management of serious manufacturer's product inspection is not allowed through, so do not assume responsibility should the user, can find manufacturers solve business
Q:LED lamp burning halogen lamp cup of transformer
Reason is that the LED lamp cup with halogen lamp cup does not match the original transformer, lamp cup need low frequency 12 ~ 24 v dc or ac power supply, the original halogen transformer is a high frequency alternating current (ac).
Q:The 4 w LED shoot the light, can make the lamp of the study? Reading a book with
If the act is not too high, will be enough, my home 3 w, but not a study, also pretty bright, we do LED lights
