Question:

The output of the led lamp is low

The output of the led lamp is low

Answer:

The current of constant current is rated, and the voltage varies with load
This should be unsegregated, and the output should be around 75v.He is unsegregated, and the output voltage is high if there is no load.
This led tube does not exist "what is the power output?" The problem. The power chip of this lamp is BP2832A, which is a special LED lighting that is used in the non-isolation step-down LED power supply. Using the patented constant-flow architecture and control method, the chip internals the 500V power switch, which requires very little peripheral component to achieve excellent constant-current characteristics. And there is no need for auxiliary windings and tests. Constant current: the output current changes without the inductance and the change of the LED voltage. The lamp is powered by 220 ac, so it requires a high-voltage electrolytic capacitor and a 250V capacitor is not enough.
See appearance, 100-150 - v 18 w 0.12 0.18 mA more precise look at the arrangement of lights and the number Look at rated lamp power estimated the actual power/(see number divided by the number of parallel light by 3.2 V) = output current to 220 V, * current * power switch power supply is ok (see appearance should be burned the IC not bad basically can be repaired, it remains to be seen whether the LED is good)
