A QL lamp (Quantum Light Lamp) is a type of compact fluorescent lamp (CFL) , often referred to as a multi-tube lamp or energy-efficient lamp . The term QL is often associated with a specific type of energy-efficient fluorescent lamp , primarily used in commercial and industrial lighting.
Features of a QL lamp:
-
Energy efficient :
- Like other energy-efficient fluorescent lamps , the QL lamp offers higher efficiency than traditional incandescent bulbs because it uses less energy for the same light output.
- They can use up to 80% less energy compared to traditional incandescent bulbs.
-
Longer lifespan :
- QL lamps typically have a long lifespan of 10,000 to 20,000 hours, depending on the quality and brand. This makes them an excellent choice for commercial and industrial applications where continuous light is required.
-
Light output and color :
- They offer a high light output relative to their power, meaning they can be brighter using less energy.
- They are often available in different light colours (warm white, cool white, etc.), depending on the specific application.
-
Usage :
- QL lamps are often used in lighting offices , retail spaces , showrooms , schools , and industrial environments . They can also be used in traffic lighting and for other applications where durable and long-lasting lighting is required.
Difference with other fluorescent lamps:
While QL lamps are technically compact fluorescent lamps, the term "QL" can also refer specifically to a particular brand or type of lamp distinguished by better light quality , faster start-up time , or extra-long lifespan . They often use an integrated electronic ballast , which provides a faster start-up time and less flicker compared to older, conventional fluorescent lamps.
In summary :
QL lamps are a type of energy-efficient fluorescent lamp specifically designed for long-lasting, efficient lighting. They are suitable for both commercial and industrial applications, offering advantages such as long life and energy efficiency .
