What is the difference between 2 pin and 4 pin PL lamp?
The main difference between 2 pin and 4 pin PL lamps is the number of pins used to connect the lamp to the fixture. A 2 pin PL lamp has two pins for connection, while a 4 pin PL lamp has four pins. Additionally, 4 pin PL lamps typically have an integrated starter and ballast, while 2 pin PL lamps may require an external ballast.
Difference between a lamp and a bulb?
A lamp refers to the entire lighting fixture that holds the bulb and provides light, while a bulb is the actual light-emitting component that fits inside the lamp and produces light when powered. In other words, the bulb is the source of light, while the lamp is the structure that houses and supports the bulb.
What is the function of the insulator in a torch?
The insulator in a torch helps to prevent the flow of electricity between different components of the torch, ensuring that the electrical current is properly directed to the desired parts, such as the light bulb or LED. This helps to maintain the functionality and safety of the torch during operation.
Difference between laser and torch light?
A laser produces a focused beam of coherent light with high intensity, directionality, and monochromaticity, making it suitable for precision applications like cutting, surgery, and communication. In contrast, a torch light produces a broader, less intense, and non-coherent beam of light, commonly used for general illumination purposes.
What is difference between bulb and lamp?
A bulb refers to the light-emitting part of a light fixture, such as an incandescent or LED bulb. A lamp, on the other hand, refers to the entire light fixture that includes the bulb, socket, and any supporting structure. In other words, the bulb is the component that produces light, while the lamp is the overall device that houses and supports the bulb.
