Feature: Why change that bulb?
By Venus May H. Sarmiento
Pangasinan (19 August) -- Ever wonder why the government is advocating the change of lighting system in every household and offices? Ever wonder why our ordinary incandescent bulb needs to be replaced by the compact fluorescent light?
Perhaps the question in a person's mind is 'Why change lights?'.
There are valid reasons.
The Department of Energy implemented a five year project called Philippine Efficient Lighting Market Transformation project or PELMATP with support form the Global Environment Facility and United Nations Development Fund.
The project aims to address the barriers to the widespread utilization of energy efficient lighting (EEL) systems in the Philippines and reduce the attendant greenhouse gas emissions in the environment?
So why change lights? It's because the incandescent bulbs that we are using is a very old lighting technology in which 80 percent of the energy used is turned into heat and only 20% is converted to light.
DOE Undersecretary Roy Kyamko explained that with incandescent bulbs, more light and more energy is consumed thus more carbon dioxide is emitted in the environment which greatly contributes to the change in climate like the global warming.
Thus the government introduced the compact fluorescent light or CFL also known as energy –saver lamp. A CFL is designed as an energy efficient, long- lasting alternative for the ordinary incandescent bulb. It is a compact form of the fluorescent tube. It has a E27'screw base similar to that of an incandescent bulb. CFLs for general lighting are usually self-ballasted.
PELMATP project manager Noel Verdote said the CFLs need only 20-25% of the energy needed to match the light output of an incandescent bulb.
"For example, the light output of a quality 20-W CFL is just as bright as that of a 100-W incandescent bulb," Verdote said.
He added that households save thousands of pesos through the life of a CFL. They likewise help the country save power demands and prevent greenhouse gas emissions.
A quality CFL has a much longer life, usually 6,000 to 10,000 hours, which is five to ten times the life of an incandescent bulb or about 750-100 hours only.
DOE advises that in purchasing your energy efficient lighting system, look for the yellow label as your guide to a wise decision on what brand you are buying. The energy label serves as a proof that the product passed the Philippine National Standards on safety and performance requirements.
DOE says using CFLs can lower power consumption thus lowering electric bills and lessesning greenhouse gases emissions.
