This flashlight uses a built-in lithium battery instead of a knot-shaped dry battery. When the battery is exhausted, you need to open the back cover of the flashlight to replace it. The battery opening and closing small switch is similar to the lunch box and the pen box switch, and will be 3 sections. The process of loading the dry battery against the spring is also reminiscent of the age of appliances that used the 5th and 7th dry batteries.
The flashlight can only switch the power supply, and can't adjust the brightness of the light. However, because the design of the reflector is very reasonable, the LED bulb can perform a wide range of illumination, and the illumination range is almost double that of the ordinary small LED bulb. The life of three dry batteries is about 10 hours. As the power is reduced, the light of the light bulb will become weaker and weaker.
This flashlight is not a product that MUJI intends to sell on a large scale. It can only be regarded as a concept product full of nostalgic colors. At present, this flashlight can only be purchased at the Mujiyama Concept Store in Tokyo, Japan. The price is about 2,900 yen (about 192 yuan).
AD8 standard floating Solar Cable is a kind of equipment used for floating photovoltaic power generation. It consists of photovoltaic cells that convert solar energy into electricity. The device is designed to float on the water, while it can be fixed to the water by a buoy and anchorage device to prevent drifting.
AD8 standard floating solar cable has the following characteristics:
1. Efficient use of solar energy: photovoltaic cells can convert solar energy into electricity to achieve efficient power generation.
2. Environmentally friendly: photovoltaic power generation does not produce pollutants and greenhouse gases and is environmentally friendly.
3. Save land resources: Floating solar cable can use the space on the water surface, saving the use of land resources.
4. Strong wind and wave resistance: floating solar cable adopts stable design, has strong wind and wave resistance, and can operate normally in bad weather conditions.
5. Easy installation and maintenance: Floating optical cables are relatively simple to install and maintain, and can be quickly deployed and adjusted.
AD8 standard floating solar cable is suitable for a variety of water environment, such as lakes, reservoirs, rivers, etc. It can be used in power stations, farmland irrigation, drinking water treatment and other fields to provide local clean energy and power supply.
