SOFIRN HS42 Headlamp 2100lm 18650 EDC USB C Rechargeable Flashlight SST40 LED Torch with Magnetic for Camping

With extended use, the lamp proves reliable. The 3000 mAh battery lasts a long time according to users, especially in medium modes. The metal body is durable and doesn't feel cheap. Some users noticed the lamp heats up faster in turbo mode than older brand models, but this doesn't affect functionality. The magnetic mount holds well on metal surfaces, though it may be less reliable on thin materials.

The main complaint is the complex control scheme — the lamp has only one button and modes are switched through click combinations (single click, double click, triple click). Most users adapt to this within minutes, but some find it unnecessarily complicated. One reviewer from Germany questions the stated brightness — comparing it to his 1200-lumen lamp which seemed brighter, though the HS42 still meets his needs. The button is sensitive and can accidentally activate in a backpack.
