| A Philips Lighting CFL. |

Question: In terms of Part L of the Building Regulations - "The efficacy target of greater than 40 lumens / circuit-watt remains. However, guidance is given on determining the number of lighting points by the area of dwelling floor area, rather than by the number of rooms. One energy efficient fitting / 25m2 and one / four fixed light fittings is now required."
Does this mean that if I use compact fluorescent lamps (CFLs) in all my fittings, that I will comply, or do I have to use 'energy efficient' luminaires?
Answer: Compact fluorescent fittings are energy efficient sources that will produce more than 40 lumens/W. If you have one of these luminaires for each 25m2 you will be meeting the requirements. As long as the luminaire that you choose does not contain either ES or BC lamps, then the luminaire will comply.
