Kerala will impose a ban on the sale of compact fluorescent lamps (CFL) and incandescent (filament) bulbs starting November this year as part of sustainable energy policy.
Context
Kerala will impose a ban on the sale of compact fluorescent lamps (CFL) and incandescent (filament) bulbs starting November this year as part of sustainable energy policy.
Filament-free project:
- The announcement is in line with the government project of ‘Filament-free Kerala’ envisaged in 2018 as part of the state’s Urja Kerala mission.
- Filament Free Kerala project is for replacing the entire Incandescent Lamps & CFLs of domestic consumers in the state by energy-efficient LED bulbs.
- The project is implemented by the Kerala State Electricity Board Ltd. and Energy Management Centre, Kerala.
|
In 2018, Kerala has launched 'Urja Kerala Mission', an aggressive Energy generation and Conservation program - aimed at the integrated development of the electricity sector in the state. It aims at implementing FIVE important projects-Soura, Filament free Kerala, Dyuthi 2021, Transgrid 2.0 and e-safe. |
Reason behind the ban:
- The mercury in a fluorescent bulb can be released as both dust and vapour if the light is broken.
- This toxic element is dangerous to people and animals and can easily migrate through the environment in the air, water and soil.
- LED bulbsuse about 40% less power than fluorescent lights, and 80% less than incandescent lights, to produce the same amount of light.
Difference between CFL, Incandescent and LED:

Longevity |
Usually 6,000 to 15,000 hours. Up to 35,000 hours. |
2,000 hours |
20,000 to 50,000 hours |
|
How they work |
Fluorescent bulbs generate light by sending an electrical discharge through an ionized gas. |
Incandescent light is emitted by heating the filament present in the bulb |
The LED is a light source which uses semiconductors and electroluminescence to create light. |
|
Materials used |
Argon, mercury vapour, tungsten, barium, strontium and calcium oxides |
Argon, tungsten, filaments |
Gallium arsenide (GaAs) and gallium phosphide (GaP) |

Why LEDs?
- Light Emitting Diodes (LEDs) use about 75% less energy than a typical incandescent bulb
- LEDs contain no mercury and have a much smaller environmental impact compared to CFL bulbs
- LED Light lasts up to 50 times longer than the conventional halogen light bulb and 10 times longer than a CFL light bulb
- LED Lights are instant on so they do not require any warm-up time compared to other light bulbs
- LEDs don’t give off heat making it cooler to operate and may even lower your A/C Bill.
- Switching to LEDs can reduce electricity and maintenance costs of a commercial building by up to 30%
- An incandescent lamp converts about 10% of the energy fed to it into the light, whereas LEDs convert nearly 100% of the energy they consume as light. LED lights are way more cost-effective than traditional incandescent.
