Compact fluorescent Light (CFL) is also called compact fluorescent light, energy-saving light, and compact fluorescent tube. Bulb hasn’t changed much since Thomas Edison introduced it in 1879. Thomas Edison Bulb is replace by the compact fluorescent light bulb( CFL). Since the 1940s, People have installed fluorescent lighting in their garages, kitchens, bathrooms, utility rooms, and recreation rooms. In the 1980s, lamp manufacturers developed a smaller, compact version of the fluorescent lamp as an alternative to incandescent bulbs for other areas of the home. The awareness of energy conservation are key factors leading to a high growth rate in the Indian market for Compact Fluorescent Lamps (CFLs).

CFL Bulb

The size of the CFL market currently pegged at 230 million units is expected to exceed 400million units by the year 2014. The market is being driven both by growing adoption by new consumers as well as replacements. CFLs contain argon and mercury vapor housed within a spiral-shaped tube. When electric current passes through mercury vapor, the mercury emits ultraviolet energy. When this ultraviolet energy passes through the phosphor coating, it produces light very efficiently. The amount of mercury in the most popular and widely used CFLs is minimal, ranging between 6 mg to 3.5 mg. Though some CFLs contain mercury higher that 6 mg, the Bureau of Indian Standards, Government of India is preparing standards to ensure that minimum qty. of mercury is used in CFLs and other fluorescent Lamps. The Bureau of Indian Standards is in process of preparing standards prescribing for minimum use of mercury in CFL Lamp. These standards are likely to be ready by end of 2009. Since the CFL Standards are mandatory in India, no manufacturer will be allowed to use mercury in CFL more than the prescribed level.

Importance of CFL bulbs

CFL bulbs consumes 75% less energy than incandescent bulbs while lasting up to 10 times longer—is a popular, energy-efficient and cost-effective replacement for the nation’s soon-to-be-phased-out base of incandescent bulbs. CFLs can help you save money by use less energy, reduce light bulb changes and lower greenhouse gas emissions.

Harmful Effects of CFL Bulbs Researchers at Jackson State University in Mississippi say once broken, such bulbs can continuously release mercury vapor into the air for weeks or even months, and the vapor can exceed safe exposure levels.

A team of Stony Brook University researchers looked into the potential impact of healthy human skin tissue (in vitro) being exposed to ultraviolet rays emitted from compact fluorescent light (CFL) bulbs. CFLs are Safe When Placed Behind Additional Glass Cover(ScienceDaily).

Many individuals are finding that compact fluorescent bulbs cause migraine headaches. But there is no data available Behind CFL-Migraine Claim.

Precautions to take when a CFL breaks

  • Have people and pets leave the room.
  • Air out the room for 5-10 minutes by opening a window or door
  • Carefully sweep up all the fragments, wipe the area with a wet towel
  • Dispose of all fragments, including the used towel, in a sealed plastic bag.
  • Do NOT use a vacuum.

Safely dispose of a CFL

Broken CFL bulbs can be put in a polythene bag and handed  over to the garbage collector personally, informing him that the bag contains CFL lamp.

The Ministry of Environment and Forest of India has prepared  guidelines on safe disposal and recycling of mercury from used lamps. Central  Pollution Control Board in association with Lighting Industry will implement the  guidelines. Under these guidelines, one of the important factors for action is  decided to appoint “Lamp Recycling Units” (LRUs). Very soon burnt CFL and  Fluorescent Lamps will be collected from consumers and transported to the LRUs.
