Question

mention any two reason for considering fluorescent lamp more effective than filament lamp​

Answer 1

The phosphor fluoresces to produce light. A fluorescent bulb produces less heat, so it is much more efficient. A fluorescent bulb can produce between 50 and 100 lumens per watt. This makes fluorescent bulbs four to six times more efficient than incandescent bulbs.

Explanation:

Fluorescent lamps also do not produce as much heat as traditional lighting options. They make about 75% less heat compared to an incandescent bulb because they are not using resistance to emit light. That also results in an energy savings, and also helps to keep whatever room they are in at a cooler temperature.The most common reason people use compact fluorescent bulbs is to save energy. You probably don't want to use a CFL bulb in the vintage chandelier hanging above your dining room table. However, there are some other applications for these lamps that you see quite often.

Hope this helps you
