Energy efficient lamps

A typical application for a fluorescent luminaire is in suspended ceiling lighting modules used in many commercial buildings. Energy-efficient lamps use... 

Use energy more efficiently - use energy-efficient lamps and A -rated equipment. 

A reasonable number of internal lighting points should be wired that will only take energy-efficient lamps such as fluorescent tubes and compact fluorescent lamps, CFLs. 

Mr. Hilary Benn, the Environment Secretary, has announced that the traditional GLS light bulbs of 150, 100, 60 and 40W will begin to be phased out by 2010. Thus, households will have to use more energy-efficient lamps in the future. 

Energy-efficient lamps use electricity much more efficiently than an equivalent GLS lamp. For example, a 20W energy-efficient lamp will give the same light output as a 100 W GLS lamp. An IIW energy-elficient lamp is... 

Fluorescent tubes and CFLs are energy-efficient lamps. 

However, enei -efficient lamps are expensive to purchase and they do take a few minutes to attain full brilliance after switching on. They cannot always be controlled by a dimmer switch and are imsuitable for incorporating in an automatic presence detector because they are usually not switched on long enough to be worthwhile, but energy-efficient lamps are excellent for outside security lighting which is left on for several hours each night. 

The electrical contractor, in discussion with a customer, must balance the advantages and disadvantages of energy-efficient lamps compared to other sources of illumination for each individual installation. 

Identify the energy-efficient lamps on the following list ... 

A reasonable number of internal lighting points should be wired that will only take energy-efficient lamps such as fluorescent tubes and compact fluorescent lamps, CFLs, which have an efficacy greater than 40 lumens/watt. They should be installed in the areas most frequently used such as hallways, landings, kitchens and sitting rooms to a number at least of ... 

Over the next few years the government will phase out GLS lamps so that we will have to use more energy-efficient lamps such as compact fluorescent lamps (CFLs). 

Changes to the Building Regulations now require an electrician to make reasonable provision for energy-efficient lamps and controls. Use five bullet points to describe what we must now do.
