Taiwan sets minimum efficacy for LED lighting
Lighting magazine reports that LED lighting in
Taiwan must have a minimum efficacy of 70lm/W, the Ministry of Economic Affairs
(MOEA) has announced. The new legislation requires all indoor warm-white LED lamps
to have a minimum efficacy of 70 lm/W, while cool-white LEDs must be more
efficient, reaching a minimum of 75 lm/W.
The Global Lighting Association (GLA) welcomed the
move, saying that minimum effiacy requirements should be set at such a level
that good-quality products are widely available and at an affordable price.
“From the GLA’s position,” explained GLA representative Michael Ng, “we
globally support one minimum level of performance for lighting products, just
like what is announced by Taiwan’s MOEA Bureau of Energy. This is very
different from just an energy labelling scheme. In general this serves the
purposes of ensuring safe and quality products for the consumers, maintaining
interoperability and competition on performance.”
Ng, who is also the director of international
affairs for the Taiwan Lighting Fixture Export Association, added: “There are
adequate surveillance and penalties in place to ensure that the vendors are
truthful and the standards used are internationally harmonised.”
“It’s an interesting turn of events,” commented Iain
Mcrae, head of global lighting applications at Thorn Lighting and past SLL
president when Lighting invited him to comment on Taiwan’s new standard. “The
move is clearly designed to discourage people using high colour temperature, or
perhaps to encourage retailers or manufacturers to favour warmer light by
making it easier to comply.”
But he isn’t sure if the move is going to have a
knock-on effect: “Whether it will catch on on a global scale is a difficult one.
We see general disquiet over the use of high CCT in the outdoors in many
countries. Generally it’s not liked, but that may be a more historic thing.
Previously such cold colours were simply not available. In some countries,
South Africa, for example, there is generally a wider acceptance of colder
colours, less so in Europe.”
Lighting in Taiwan accounted for 10.9 per cent of
the country’s total power consumption in 2013, according to MOEA’s Bureau of
Energy (BOE). Residential lighting accounted for 40 per cent of the total
lighting power consumption.
