What should be used to effectively extinguish a light that is on fire?

Using a fire extinguisher is the most effective method to extinguish a light that is on fire, particularly if it involves electrical components or flammable materials present in or around the light. Fire extinguishers are specifically designed to combat various types of fires based on their classifications (A, B, C, etc.), and selecting the appropriate fire extinguisher for the type of fire is crucial for achieving effective results while ensuring safety.

When a fire is ignited from electrical appliances or wiring, using water could exacerbate the situation because water can conduct electricity and pose a risk of electrical shock. Similarly, while fire blankets can smother small fires effectively, they may not be practical for extinguishing larger or uncontrollable fires involving lights or fixtures, especially if access is difficult. Sand can also be used in some instances to smother certain types of fires, but it may not be as effective or safe for electrical fires.

In summary, using a fire extinguisher is the recommended approach because it is tailored for various burn scenarios and provides the best chance of safely and effectively putting out the fire.
