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.
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.
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.
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.
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.
The difference between a pole lamp and a normal lamp is very miniscule. A pole lamp stands on a pole and the lights are strung up like they are on a tree.
