I bought this lamp as additional work lamp. A Kunzer PL-023 SCHWARZ I have been around for 4 years now. I am completely satisfied. This lamp lights even brighter with 30 LEDs. The battery lasts really long! The possibilities are endless! The magnetic base is strong and is fully sufficient to carry the weight of the lamp. The lamp keeps on every steel or iron girders or door frames of iron easily (no aluminum.). They will not slip away! Therefore, I can not understand the previous opinions in this direction. The charging cable (length) is sufficient for a cordless LED lamp. The power supply you have to have this for longer missions if necessary. But there can be divided. Only a 12 volt version as loading facility across the car would have been for my applications of advantage. A great LED work lamp -> strong buy recommendation!
