What are stadium lights? Stadium floodlights are high-power, high-output lighting devices that can emit enough light (lumens) to illuminate large areas, such as sports facilities, playgrounds, large parking lots, large buildings, and industrial venues. The most commonly used lighting technologies are light-emitting diodes (LEDs) and metal halides (MH). High stability flip-chip supplier shares with you.
In order to correctly review the advantages of LED stadium floodlights, let us review some definitions:
1. Lumen: Lumen is the international unit of luminous flux, which is equal to the amount of light emitted per second from a candela uniform light source in a solid angle unit.
2. Footcandle (Fc): Footcandle is a non-international unit of illuminance or the illuminance of a Candela light source projected onto a surface one foot away.
3. Lumens and foot candles: Simply put, lumens measure the light emitted by a light source, and foot candles measure the amount of light that reaches an illuminated object (such as the ground, statue, work area, etc.).
4. Efficacy: How effective is your light source; usually measured in lumens/watt (LpW).
5. Working time: The service life of the light source is measured by a certified laboratory and measured in working hours, or how many hours can be illuminated during its service life.
6. Life Maintenance 70 (LM70): Most LED lighting life is measured by the LM70 test, which means that when the specified life is reached, the light will still emit 70% of its initial lumen. For example, if an LED luminaire is rated for 100,000 lumens, LM70 is 80,000 hours and is used for 10 hours per day (3650 hours per year), then in 21.92 years, the light will still emit 70,000 lumens (a 30% reduction).
When it comes to the costs associated with stadium lighting, there are several factors to consider. The first is the cost of fixtures. Unfortunately, this is often the only factor that people think, because inferior technologies tend to have lower upfront costs, but higher living costs.
Second is the efficacy of the light source; with the advancement of technology (especially LED lighting), you can now use lower power to achieve the same light intensity. For example, the efficiency of the old LED stadium floodlights is about 100 LpW, while the new design allows the efficiency of more than 150 LpW. Therefore, when you used to replace a 1000-watt metal halide with a 300-watt LED fixture, now you only need 200w led chip that can achieve the same 30,000 lumens. Of course, this will increase your energy and reduce lighting from a powerful 70% to an amazing 80% or higher!
Of course, you also have to consider the life of the light source; most metal halide lamps have a lifespan of 5,000 to 10,000 operating hours until they are completely extinguished. LEDs typically reach 50,000 to 100,000 operating hours before reaching their LM70 level.
