Question 1

Is it worth buying a CFL bulb instead of an LED bulb in India today?

Accepted Answer

For most homes, an LED bulb is the better choice because it uses about 40% less power than a CFL of similar brightness and typically lasts 15,000 to 25,000 hours compared to 6,000 to 10,000 hours for a CFL. LED prices in India have also dropped sharply, so the upfront cost difference is now small. On LedDisplay you can compare current CFL and LED prices side by side to see the real difference for your wattage.

Question 2

Which LED bulb wattage should I buy to replace my CFL bulb?

Accepted Answer

As a rough guide, an 8–9W LED replaces a 14–15W CFL, a 12W LED replaces a 20W CFL, and a 15–18W LED replaces a 23–30W CFL. Check the lumen rating on the pack rather than watts alone, since brightness can vary between brands. Most CFLs in India use a B22 pin base, so choose an LED with the same base for a direct swap.

Question 3

How do I safely dispose of a used or broken CFL bulb in India?

Accepted Answer

CFLs contain a small amount of mercury, so they should not be thrown in regular household waste. Under India's E-Waste Management Rules, they should go to an authorised e-waste collection centre or a manufacturer take-back point. If a CFL breaks, ventilate the room, avoid using a vacuum cleaner, and collect the pieces with stiff paper and tape before sealing them in a bag.

Question 4

Why do CFL bulbs take time to reach full brightness?

Accepted Answer

CFLs work by heating mercury vapour inside the tube, which takes anywhere from a few seconds to a minute or more to reach full output, especially in cooler rooms. Frequent switching on and off also shortens their lifespan. This is one reason many Indian buyers now prefer LEDs for staircases, bathrooms and other areas where lights are switched often, and LedDisplay lists instant-on LED alternatives in the same price range.
