In Tool, you will find a variety of flashlights, such as pen flashlights, rechargeable flashlights, diving flashlights and so on.
Pen flashlight, just as its name implies, is a flashlight in the shape of a pen. The original intention of the pen flashlight is to provide lighting tools for doctors, engineers and other professionals. Because these industries have some special requirements on the appearance and performance of flashlights, such as beauty, concealment, and convenience. That’s why pen flashlight was born.
For doctors, this is used to facilitate the lighting of the mouth and ears. Because the space is narrow and the distance is short, the low-light mode is often used. For engineers, the appearance of pen flashlight is more in line with their professional requirements when doing engineering drawing interpretation at night.
Rechargeable flashlight is a new type of lighting tool with light-emitting diodes as the light source. It has the advantages of power saving, durability, strong brightness, etc. The rechargeable flashlight is a handheld electronic lighting tool that can be repeatedly charged. Rechargeable flashlight is environmentally friendly and usually uses LED bulb. It is suitable for going out at night and lighting for power outages.

Due to the dim light on the seabed, people expect to be able to see everything clearly on the seabed, and a lighting tool with good waterproof performance has become an urgent need. It should be noted that the diving flashlight magnetic control switch has limited pressure on the switch port and is susceptible to the penetration of impurities in the sea. Some sealing rubber rings are even susceptible to corrosion, so the diving depth is generally within 30 meters.
