Okay lamp, but battery life at medium power only 4-5h. That is, not enough power for the whole working day. The Petzli power button function is also frustrating. You have to go through the whole cycle every time, ie you have to knock the knob dozens of times a day. For almost the same price you get the Lumonite Compas R with a bigger battery and a simpler interface.
Top lamp petzel reliability, power efficiency, usability in the same package 🙌 better allowed to apply. Lumonite's latest model crashes into its own impossibility as an aluminum-framed summer lamp. You can really rely on this lamp 🤝
