1. How are fluorescent lamps/CFLs different from incandescent lamps?

In incandescent lamps, electrical currents directly heat up a filament till it is white hot and emits light, This is different from fluorescent lamps/CFLs in which the heat excites mercury vapor to produce ultra-violet light, which in turn causes a phosphor to fluoresce and emit visible light.

2. Will I be able to derive any monetary savings by switching over from incandescent to fluorescent lamps/CFLs?

Yes, fluorescent lamp/ CFL technology is more energy efficient and uses less power to generate the same amount of light. In addition, fluorescent lamps can last up to 10 times longer, depending on the make and model, under similar operating conditions. The lower energy consumption and longer lifespan can lead to overall savings over a period of usage.

3. Do fluorescent lamps/CFLs contain mercury?.

Yes, fluorescent lamps/ CFLs contain trace amounts of mercury within the glass enclosure. Mercury plays a pivotal role in the production of light and cannot be totally eliminated. However, over the years, technological advancements have led to reduction in the quantities of mercury needed. The mercury is safely kept within the lamp and will not escape unless the glass is broken.

4. Should the mercury be a cause for concern if I break a fluorescent lamp/CFL?

The small amount of mercury present in fluorescent lamps is unlikely to pose a threat to human health. Nonetheless, it is prudent to manage broken fluorescent lamps with care such as by minimizing exposure and avoiding direct contact.

5. What should I do if I break a fluorescent lamp/CFL?

In the event of a broken lamp, open the windows for ventilation and leave the room for about 15 minutes. At the end of the 15 minutes, use a broom to sweep up the broken pieces and put them into a plastic bag. Avoid using bare hands or a vacuum cleaner to pick up the broken pieces. Next, wipe the affected area with a damp cloth and dispose of the damp cloth into the same bag. Finally, secure the opening of the bag and drop into the refuse chute or bin.
