This 13W CFL bulb uses approximately one-quarter of the energy of a comparable 60W incandescent bulb, offering up to 75% energy savings. When used with a dimming ballast, energy savings can be even greater. ### How to choose a light bulb for India?

Consider energy efficiency, lifespan, and light quality (lumens, CRI, color temperature) for your specific needs. This Sylvania bulb is designed for electronic ballasts and offers long life and dimmability. ### Are there any side effects of using CFL bulbs? CFL bulbs contain a small amount of mercury.
