Compact fluorescent lamps (CFL) are not only environmentally friendly and energy saving but also, by and large, electrically safe.
This is the verdict of a test published by the Consumer Council in collaboration with the Electrical and Mechanical Services Department (EMSD) to assess the safety of this product.
The safety test focused on 10 different CFL models ranging in power from 7 to 25 watts and in price from $28 to $260.
Eight out of the 10 samples were awarded the top score of 5 points out of a 5-point rating in overall safety assessment based on: resistance to heat, flame and ignition, fault conditions, cap temperature rise, electric strength and insulation resistance after humidity treatment, mechanical strength, labeling, and interchangeability.
Two of the samples scored slightly lower with only 4 points in the overall safety rating due to their non-compliance with the IEC (International Electrotechnical Commission) standard on resistance to heat.
The suppliers of the models in question have undertaken to change the material of the plastic lamp cap in order to comply with the safety requirement.
The safety labeling of some samples was found unsatisfactory and in need of improvements. One sample did not have marking of the rated current and the instruction/warning statements were in Japanese only.
Another was missing the "non dimmable" label - it is not advisable to connect dimmer to most CFLs unless otherwise specified because it will lead to a sharp temperature rise in a short period of time.
In choosing compact fluorescent lamps, consumers are advised to consider those with EMSD's energy efficiency label indicating that they have been tested successfully to meet the minimum energy efficiency and performance requirements of the scheme.
In comparison with the traditional tungsten light bulbs, compact fluorescent lamps can save up to 75% electricity consumption and last 7 to 9 times longer in life span.
Due to their being usually larger in size and heavier in weight, consumers are also advised to pay attention to the loading and stability when applying a number of CFLs to light fixtures. If in doubt, seek the help of an experienced technician to ensure safety.
