An Energy Saving Lamps actually a compact fluorescent lamps (CFL). It was designed to replace an incandescent lamp. Compared to general incandescent lamp, CFL (Energy Saving Light) gives the same light by using one-fifth to one-third electric power and last seven to fourteen times longer. An Energy Saving Light or CFL has a higher price than a general incandescent lamp but you can save 70-80% electric power cost over the lamp’s lifetime. Energy Saving Lamps have a rated life of 6,000–15,000 hours, whereas general incandescent lamps have a rated life of 750 or 1,000 hours.
Health and Environmental impact of Energy Saving Lamps
Like all fluorescent lamps, Energy Saving Light (CFL) contains mercury, a neurotoxin (especially dangerous to children and pregnant women) as well as it generates UV ray which is harmful for human health. Initially, many countries introduced this light to cut cost.
But when the scientists observed that there is a significant emission of UV ray from CFLs (energy saving light), they suggested to reduce uses of these lights. According to the European Commission, CFLs may cause an added health risk due to the UV (Ultra Violet) ray and blue ray. This UV light harms our skin and may cause skin cancer also. Moreover, its disposal system is hazardous as broken CFL lights emit substantial amount of Mercury-vapor. As per their suggestions, most of the developed countries left the use of CFLs but the under developed as well as developing countries are still using CFLs to cut costs.
Considering all situations, scientists again developed alternative of CFLs which is called LED Light. An LED lamp is a light-emitting diode (LED) product which is assembled into a lamp. LED lamps have more life than general incandescent lamps as well as Energy saving lights. With some chips, it is able to emit more than 100 lumens per watt.
Initially, LED Light is more costly than CFLs but its power consumption cost is lower than CFLs. It has very low UV ray emission that is little bit safe for human being. Considering all above things, scientists are suggesting for using LED Lamps instead of Energy Saving CFLs.
