EU switch on to LED lightbulbs before September’s halogen ban

From the end of this month halogen lightbulbs are to be removed from the market across Europe, with households expected to switch to LED lights – an electric light that produces light using light-emitting diode (LED) which cost more but last far longer and use much less electricity than energy-hungry halogens.

● What is the ban?

Old-fashioned incandescent bulbs were the first to go, in 2009, and in 2016 the phased removal of halogens began in an EU-wide effort to improve energy efficiency and cut carbon emissions. Halogens are hugely wasteful of energy – the Energy Saving Trust estimates that the typical halogen uses 11 pounds of electricity a year while a replacement LED would use only 2 pound’s (NT$ 81) worth. What’s more, halogen bulbs typically fail after about two years, while LEDs should last for around 15 to 20 years on the same usage.

● How do I know which LEDs to buy?

A generation brought up on bulb brightness expressed in terms such as 100w or 60w has to learn the new vocabulary of “lumens”. Wattage measures power or energy, while lumens measure light output. Broadly speaking, a 60w bulb gave off around 700 lumens, while a 100w one is equivalent to more than 1,300 lumens. But stores such as John Lewis still label LED lights primarily with watts; it says its 8.5w “classic” LED bulb is equivalent to a 75w incandescent bulb, while a 13.5w LED is equal to a 100w old-style bulb.

● How much do they cost?

More than incandescent bulbs. At B&Q, “Diall” LED bulbs offer 1,520 lumens (it says that is equal to the old 100w bulb) and cost 8 pounds. But remember how much less electricity they use and how long they last. If households replaced 10 halogens with 10 LEDs, the long term savings are equal to about 112 pounds a year, says Philips.

● 此禁令的內容為何?

歐盟在二○○九年,首先淘汰老式的白熾燈泡,並自二○一六年始,分階段淘汰鹵素燈,以提高能源效率和減少碳排放。鹵素燈非常浪費能源──據節能信託基金會估計,一枚典型的鹵素燈泡每年耗費 的電力值十一英鎊(約新台幣四百四十四元),但若使用LED燈泡,只需花費兩英鎊(約新台幣八十一元)。更重要的是,鹵素燈大約使用兩年後就會壞,而LED燈在相同的情況下可使用十五至二十年。

● 應選購何種LED燈泡?


● LED燈泡要花多少錢?

比白熾燈泡貴。B&Q特力屋的Diall牌一五二○流明LED燈泡 (相當於舊制一百瓦燈泡),售價是八英鎊(約新台幣三百二十三元)。但請留意,這燈泡可以少用多少電,以及增加了多長的壽命。飛利浦公司表示,若在家中把十個鹵素燈換成十個LED燈,那麼長期下來,每年約可節省一百一十二英鎊(約新台幣四千五百二十三元)。
