But the spotlight was not functional after charging.
I opened the case and found a wire to the PCB demolished.
Not the solder joint was torn, but the wire had a piece of copper foil torn from the circuit board.
This is a design flaw. To this place has a hole in the printed circuit board and a soldering surface on both sides. Then can no longer happen.
Since solder joints not demolish by themselves, I suppose, the spotlight has already been opened and complained.
Then the lamp worked - headlights I do not say any more at the pitiful light output.
The switch is very difficult to operate. Not with cold hands or even gloves more.
The mechanical design is cheap (which is ok for the price), but also flawed.
An example: When you open the lamp, the entire LED support can rotate. This has probably led to the demolition of the wire described above.
To prevent would be by a guide groove in the lamp housing and the LED support. Cost you a penny, but just a little thought in the design.
Summary:
Defect delivered.
Poor constructed.
For the generated light output too large and too heavy.
Go back.
