What Is a Floodlight?
A floodlight is a lighting fixture that uses a reflector or lens to emit light in a specific direction.
They are used when you want to focus on a target rather than illuminate the entire room, as is the case with light bulbs and fluorescent lamps.
There are four main types of light sources: LEDs, mercury lamps, metal halide lamps, and halogen lamps.
In recent years, LEDs have become the mainstream. The reasons for this are that LEDs consume less electricity, have a longer lifespan, and instantly become brighter. In addition, since the manufacture, export, and import of mercury lamps was banned from 2020, mercury lamps are being replaced by LEDs.
How to Use Floodlights
Floodlights are electrical devices, so to use them, you must first secure a power supply. There are types that supply power by plugging a cable into an outlet, and cordless types that use a rechargeable battery. Portable generators are used at construction sites and other locations so that lighting can be turned on anywhere.
Installation methods also vary, and sometimes a large number of them are installed in a single frame, as in baseball stadiums. Other times, they are suspended from the ceiling or installed with stands to adjust the height.
How to Select Floodlights
One way to choose floodlights are by the type of light source.
- LED
LED is by far the most popular floodlights sold today, and its energy-saving performance is far superior to that of conventional light sources, and its long life makes it safe to choose floodlights other than LED unless you have a special reason to choose it. - Mercury Lamps
Mercury lamps used to be a mainstream light source, but their manufacture, import, and export are now banned because they use mercury, which is harmful to the human body and the environment. - Metal halide lamps
Metal halide lamps also contain a small amount of mercury, but since they meet mercury content standards, they are not subject to regulation. Metal halide lamps can be made more energy efficient or emit light closer to natural light by changing the ratio of the gas mixture contained in the lamp. - Halogen Lamps
Halogen lamps generate heat when emitting light, so snow does not accumulate on the lamps even if it snows. They also act as heaters to slightly raise the ambient temperature.
