The ordered inspection lamp was delivered on time and neatly packaged. The luminance I can not measure, but should be within the specified range. When focusing a square of about 2m is strongly illuminated in about 40m distance. The square is built on the square light-emitting diode. But this also the end of the adjusting thread is reached. A little about it beyond more and the focus ring drops. A Endlagensicherung does not exist. The 5 light modes can be set. When inserting the Accu attention is required. There is no mechanical reverse polarity protection. The rear view mirror is not clean. Whether you get it by brushing away is questionable. The charging socket is located opposite the power switch. It is protected by a rubber-like covering. The contact-making is very critical. Without lateral pressure on the charging plug there was no contact. A control is possible only on AC adapter with the charging indicator. The included car charger has not been tested.
