When the LED flashlight is charged, the bulb turns dark, the light is dim, and the spot is a little yellow. It has been charged for 5 hours
Lead terminal voltage greatly exceeds the rated value, if the driver then there may be damaged. To sum up, according to the inspection process you are so simple, basically all components may be bad, such as to the exact scope of fault, to provide more data.
Probably when charging voltage is very high, then open the lamp on the current will greatly exceed the rated value, the lamp aging in a short period of time, the ablation of fluorescent powder produced spot, using terminology that is a short time attenuation increase, belongs to the permanent damage can not be repaired, only the replacement, but according to this phenomenon look, there may be a battery performance has been poor, does not rule out the charge line element anomaly
