How to choose a bike light

There is a big gap between the functions and prices of many car light products on the market. How to choose the one that suits you?
The type and intensity of bike light sources are what consumers care most about, and they are also an important factor affecting the price of car lights. There are 3 kinds of most common bulbs on the market: tungsten bulbs, HID and LED. To understand the intensity of a light source, you must first know the unit of light: lumens, which represents the amount of radiant light energy per unit time, or the total amount of light emitted. The larger the lumens, the more light emitted, and of course the brighter it is.

LED (Light Emitting Diode) is an electronic component that can convert electrical energy into light energy, and has the characteristics of a diode at the same time, that is, it has a positive pole and a negative pole. The LED will only emit light when the positive pole is energized, so it is given to the tributary. The LED will glow steadily when it is powered, and if it is connected to AC power, the LED will flicker. At the beginning, it was mostly used on indicator lights and display panels. With the appearance of white light emitting diodes, it was also used as lighting. In addition to its high efficiency (about 60 lumens of 1W light), long life (about 50,000 to 100,000 hours), not easy to break, low temperature during lighting, and moderate prices, the most important thing is that it also saves energy and is mercury-free The advantages of environmental protection, so it is called the new light source of the century, and it is also the mainstream of bike lights.

HID (High Intensity Discharge) gas discharge bulb, also known as xenon lamp, has high luminous efficiency (1W luminous about 50 lumens); it was first used in sports field lighting, and later cars also used it to replace traditional halogen lamps. Due to the characteristics of high illuminance (about three times that of halogen lamps) and low power consumption (about half of ordinary halogen bulbs), the lifespan can reach 2.000~3.000 hours, and it is gradually transplanted to bike lights; HID can be said It is currently the brightest choice for bike lights, but it is expensive. It is mainly used by professional athletes and mountain adventure enthusiasts who need strong lighting.
