What is Compact Fluorescent Lamp (CFL)
A Compact Fluorescent Lamp (CFL) is a type of energy-efficient light bulb. It is designed as a more environmentally friendly alternative to traditional incandescent bulbs. CFLs are known for their compact size, energy efficiency, and long lifespan. CFLs operate by passing an electric current through a tube that contains a small amount of mercury vapor and a phosphor coating. When the current flows through the tube, it excites the mercury vapor, causing it to emit ultraviolet (UV) light. The phosphor coating on the inside of the tube then converts the UV light into visible light, resulting in the illumination provided by the CFL.

One of the key advantages of CFLs is their energy efficiency. They use approximately one quarter of the energy compared to traditional incandescent bulbs, making them a popular choice for those looking to reduce their energy consumption and lower their electricity bills. CFLs also have a longer lifespan, typically lasting 6,000 to 15,000 hours, compared to the 750 to 1,000 hours of a normal incandescent bulb.
CFLs are available in various wattages and shapes, including spiral and tubular designs. The wattage of a CFL indicates its power consumption, with lower wattages being more energy-efficient. The shape of a CFL can affect its compatibility with different fixtures, so it is important to choose the appropriate shape for the intended application.

常見問題
Why Are CFL Still Preferred Over LED
Additionally, CFL bulbs still remain popular due to their ability to emit a significant amount of heat, with almost 80% of their energy being released as heat. On the other hand, LED bulbs have the advantage of emitting very little to no energy as heat, making them even more efficient in terms of energy consumption.
Are CFL Bulbs Still Sold
However, the diverse designs of Compact Fluorescent bulbs continue to be in demand as they are considered energy-efficient and stylish lighting options. They have gained popularity, especially through brands like Plumen, and are now used not only for illumination but also as decorative elements. It is important to note that as of February 25th, 2023, there is a gradual phase-out of CFL light bulbs.
Why You Should Stop Using CFL Light Bulbs Immediately
In reality, there are several reasons why it is advisable to discontinue the use of CFL light bulbs. These bulbs have been found to emit ultraviolet radiation, which can have detrimental effects on our health. Symptoms such as dizziness and eyestrain can occur, and in more severe cases, conditions like cataracts and macular degeneration may develop.
Can I Replace My Fluorescent Tubes With LED
Yes, it is possible to replace fluorescent tubes with LED tubes or LED-integrated fixtures. If you only need to replace the bulbs, you have the option of using plug-and-play, direct-wire, or hybrid LED tubes. Among these options, plug-and-play tubes are the most convenient to install since they do not require any rewiring of the fixture.
