What are stadium lights called?
floodlight
A floodlight is a broad-beamed, high-intensity artificial light. They are often used to illuminate outdoor playing fields while an outdoor sports event is being held during low-light conditions.

What is the difference between spot lights and flood lights?
Spotlights are usually defined as lights with beam angles of no wider than 45 degrees, whereas floodlights are typically categorised by beam angles of 90 degrees and above. With a spotlight, users can almost “point and shoot” the beam of light at specific objects to better illuminate them.
Why is it called flood lights?
Why Are They Called Flood Lights? The word ‘flood’ has nothing to do with water. They are called flood lights because they are flooding the area with light.

How much power do stadium lights use?
If you use metal halide lamps, you’ll need 70,000 watts to produce 300 to 400 lux, or if you use LED flood lamps you’ll only need 35,000 watts.

Are stadium lights hot?
In lighting, heat emission is one of the most significant hazards. In a stadium packed with thousands of spectators and fans, heat and light can have devastating effects and pollution. While conventional bulbs convert up to 90% of their total energy to heat, LEDs emit nearly no forward heat.
What does Gobo stand for?
Go Between Optics
A “Gobo” is a small stencilled circular disc, and used in lighting fixtures to create a projected image or pattern. The term Gobo is short for “Go Between Optics”, describing the location where it needs to be positioned in the light path of a lighting fixture.

- Parabolic Aluminized Reflector pin spotlight.
How hot does a flood light get?
The maximum temperature of the LED flood light was just about 35 degrees Celsius (95 F). It’s of interest to note that the temperature reading of a human hand is just below 31 C (89 F), meaning that the LED flood light was only slightly warmer than a firm handshake.
