【LED】Inheriting the traditional form of kerosene lanterns! A fusion of retro warmth and the latest technology
Wanting to escape the hustle and bustle of the city and spend time healing my heart──. The lantern I encountered is an LED lantern that inherits the design of the kerosene lantern "HK500." Let's enjoy the soothing time while illuminating the campsite with gentle light.
A classic LED lantern that blends tradition and innovation

is an essential light for the outdoors. While flashlight and mobile lights are convenient, “if possible, I want to spend time away from the hustle and bustle of the city and heal my heart.” What I discovered was the “Petromax LM500 LED Lantern.”
It inherits the design of the kerosene lantern “HK500,” which symbolizes Petromax, giving it a somewhat retro and nostalgic look. The campsite is enveloped in a gentle light.

A light that can be chosen from three colors

with a maximum brightness of 500 lumens can be adjusted smoothly according to the application and mood. The color of the light can also be selected from three types: a warm 2200K like a campfire, a soft and cozy 3000K, and a bright 5000K suitable for cooking or reading. It seems handy to be able to freely control the optimal light according to the scene.
Operation is simple; just press the top push button for one second. With IP44 compliant dustproof and drip-proof performance, it can be used safely even in rain and humidity.

A digital display that shows the status

The front display shows information in the order of remaining light time, battery level, brightness, and color temperature. It has a user-friendly design that allows you to check the situation at a glance. The operation is simple, and you can switch the display just by moving the wheel. You can quickly grasp the necessary information. It seems easy to use even in night camping or dark places.
USB-C dual-port power supply & charging

Both input and output are compatible with USB Type-C. It can be used not only for charging the lantern itself but also for charging devices like smartphones.
