Compact Fluorescent

Compact Fluorescent Bulbs (CFLs) have been a cornerstone in energy-efficient lighting, bridging the gap between older incandescent technology and the newer LED options. Known for their distinctive spiral shape or enclosed tube design, CFLs offer a cost-effective solution for consumers looking to reduce energy costs without sacrificing brightness. These bulbs work by driving an electric current through a tube containing argon and a small amount of mercury vapor, generating ultraviolet light that then stimulates a fluorescent coating inside the tube to produce visible light.

CFLs consume about one-third of the energy used by incandescent bulbs and have a longer lifespan, typically lasting up to 10,000 hours. This makes them an environmentally friendly option, reducing the demand for electricity and, consequently, greenhouse gas emissions. Available in a range of color temperatures, from warm whites to cool daylight, CFLs can be used in various settings, including residential, commercial, and outdoor spaces.

While they take a moment to warm up to full brightness, modern CFLs have significantly improved in terms of light quality and time to full luminosity. They are compatible with a wide range of fixtures and are particularly effective for lighting areas where lights remain on for extended periods.

However, it's important to note that CFLs contain a small amount of mercury, requiring careful handling and proper disposal. Recycling programs are widely available to manage these bulbs responsibly at the end of their life cycle.
