Stadium lighting is an important and careful procedure which determines the audience’s comfort and player’s focus during the games. The types of lighting commonly used for stadiums include mainly LED and HID lighting. But how can we pick one of these? This can become easier by knowing the differences, or you can simply consult LEDLUCKY.
Main Difference Between HID and LED Lights
HID and LED lights are entirely two different technologies which run on different methods of producing light. HID bulbs consist of inert gas enclosed within a glass case, while LEDs are solid state technology. HIDs are known for creating a lot of heat, which may even lead to production of the UV and IR spectrum. This can be very dangerous for the people in the audience or even the players in the stadium as they pollute the air. LEDs emit only a small portion of the spectrum, so they do not waste any excess energy thus, creating more light with less energy.
Why are LEDs preferred over HIDs?
LEDs are commonly preferred over HIDs based on the Source vs System efficiency. This can be explained by discussing the measurements of both LEDs and HID, HID are measures in lumens/watt. So, their system efficiency is affected by numerous factors that may include loss of trapped light, protective lens, non-standard temperatures, loss due to conversion of power. Mainly, the system efficiency for HID lights amounts to only 25 percent, where LED lights produces 50 percent efficiency of light. So, in the case of efficiency, LED takes the lead.
Another one of the major factors which distinguish the LEDs from the HIDs is the maintenance and replacement costs of the stadium lighting. Stadiums are themselves big and the surface area is wide enough which needs other maintenance as well, such as grass/soil, seats, pitch etc. So, when it comes to lighting, repetitive maintenance and replacement can be costly. HIDs have a much shorter life span than LEDs and are more dangerous in terms of air pollution and are more prone towards heating up/burning, are dimmer, and have very short warranty period. Contrary to this, LEDs prove to be much more durable and have a longer life-span making it easier for stadium usage. So even if LEDs are higher in cost than HIDs, they technically are worth it because of their quality and quantity.
Colour Temperature Difference
Another one of the differences why LED is preferred is because the HID bulbs are mostly monochromatic yellow with an absorbing Colour Rendering Index which makes everything appear yellow in its light. LEDs give off white colour commonly, which absorbs into the spectrum leaving no discomfort for the audience or the players in the stadium. LEDLUCKY lighting offers excellent LED lighting options for stadium with guaranteed durability.
The bottom line simply is that LEDs are better for stadium lighting because of the potential they have and the advantages they provide. This is why they are so commonly used and have almost replaced the traditional lights. LEDs have a lot of future potential, especially concerning the sports world.
