The Threat of our Time - Global Warming

The world is warming up. Global warming refers to the increase in the average measured temperature of the earth's near-surface air and oceans since the mid-20th century, and its projected continuation. Evidence reveals that a 0.6 degree rise would kill 150,000 people every year. Glaciers, permafrost and sea ice are disappearing. Sea levels are rising, seasons changing and extreme weather becoming more extreme. As temperatures increase further, there will almost inevitably be more flooding, more droughts, more disease, more famine and causing the destruction of entire ecosystems and species.

This massive and rapid change to our climate is likely to be caused by the greenhouse effect. Recent researches show that CO2 emissions are occurring at a rate doubling the capacity that the earth can assimilate. Furthermore, CO2 concentrations in the atmosphere are now 380 ppm, which is higher than any measured records over 4,000,000 years. The delicate balance of atmospheric gases that sustains life is thickening, trapping more and more heat and irreversibly changing our world.

Change One Light Bulb at a Time

Lighting is a necessity in the daily lives of people. Old-fashioned incandescent light bulbs waste as much as 95% of the energy they use. Compared with incandescent bulbs, LEDs and CFLs can save up to 80% energy. To save the world, it’s time to switch to eco-lighting products.

Energy Labelling Scheme

Many countries and regions have adopted energy efficiency policies and introduced the mandatory or voluntary Energy Efficiency Label scheme to provide information on energy consumption and efficiency to help consumers make better purchasing decisions. The energy efficiency of the appliance is rated in terms of a set of energy efficiency classes on the label. The labels also provide other useful information to the customers for comparison with various models.

Hong Kong Mandatory Energy Efficiency Labelling Scheme

"Energy Efficiency (Labelling of Products) Ordinance" has been officially announced on 9 May 2008. According to the ordinance, compact fluorescent lamp (energy saving lamp) has to carry an energy label on its package, providing information including energy efficiency category, lumen efficacy (lm/W), reference no., etc. to consumers, so as to allow them to distinguish products with higher energy efficiency and make a smart and eco-friendly shopping choice. There will be a grace period of 18 months provided to the manufacturers of the compact fluorescent lamp.

To allow for better understanding of the requirements of the "Energy Efficiency (Labelling of Products) Ordinance" by the industry players, the Electrical and Mechanical Services has issued a "Code of Practice on Energy Labelling of Products under the Energy Efficiency (Labelling of Products) Ordinance". According to the guidelines outlined in the document, the energy efficiency of the energy saving lamps will be assessed in three aspects: 1) Average Lamp Life 2) Lumen Maintenance (Assess the stability of the brightness level of the lamp) 3) Luminous Efficacy (Assess the energy efficacy of the lamp) Products will be assigned Grade 1 to Grade 5 based on its performance, with Grade 1 the most efficient and 5 the worst.

  Grade 1 Grade 2 Grade 3 Grade 4 Grade 5
Average Lamp Life Over 8,000 hrs Over 6,000 hrs 6,000 hours or below
Lumen Maintenance
(2,000 hours)
Above 80% Above 78% 78% or below
Rated Lamp Wattage Luminous Efficacy (X) Note (1)
≤10W X ≥ 49.5 49.5> X ≥ 45.0 45.0> X ≥ 40.5 X < 40.5 N/A
11-20W X ≥ 55.0 55.0 > X ≥ 50.0 50.0 > X ≥ 45.0 X < 45.0 N/A
21-30W X ≥ 60.5 60.5 > X ≥ 55.0 55.0 > X ≥ 49.5 X < 49.5 N/A
≥ 31W X ≥ 66.0 66.0 > X ≥ 60.0 60.0 > X ≥ 54.0 X < 54.0 N/A
1. 50% of the tested sample has achieved the their life time

2. The lumen maintenance at 2,000 hours =
The average luminous flux within 2,000 hours x 100%
The average luminous flux within the aging of 100 hours

3. Luminous Efficacy = Luminous Flux / Wattage

Energy saving lamps have to fulfilled other test requirements outlined in the document, for further details, please refer to the "Code of Practice on Energy Labelling of Products".
