Compact Fluorescent Lamps (CFLs) are energy-efficient light bulbs designed to replace incandescent lamps, using up to 75% less energy and lasting 8–15 times longer (typically 10,000+ hours). They work by exciting mercury vapor to produce ultraviolet light, which causes a phosphor coating to emit visible light, often used in homes and offices.

Key Features and Benefits

Energy Savings: Consumes one-fourth to one-third the power of comparable incandescent bulbs.

Lifespan: Lasts significantly longer, often between 6,000 and 15,000 hours, or roughly 5 years.

Design: Available in various forms, including spiral, stick, and tube, suitable for recessed or compact fixtures.

Colour Temperature: Offered in warm white to daylight, providing versatile, high-quality light.

Performance: While early models required warm-up time, modern CFLs often provide faster, flicker-free light.

Types of Compact Lamps

Integrated CFLs: Feature a built-in ballast, allowing them to screw into standard household light sockets.

Non-Integrated (Plug-in) CFLs: Require separate, often external, control gear (ballast), commonly used in commercial, recessed, or furniture lighting.

Important Considerations

Mercury Content: CFLs contain small amounts of toxic mercury, necessitating special disposal methods.

Environmental Factors: They do not perform well with frequent on-and-off cycles and can experience reduced lifespan in enclosed fixtures with poor airflow.

Alternatives: While energy-efficient, they are increasingly being replaced by LEDs, which are more durable, mercury-free, and longer-lasting.
