CFLs in Modern Lighting


CFLs still have a major part to play in modern energy-efficient lighting, and David Jones of Fluorel takes a look at the current status of the technology.


Despite the buzz around new and innovative LED illumination, and the continued use of traditional lighting such as Tungsten bulbs, CFLs provide a valuable option in modern lighting systems. This article describes a few of their key advantages and uses.


example, some covers can produce sparkling or twinkling effects, or a blue drop glass cover over a 200mm CFL will produce a halo of a further 50mm leading to attractive design features.


Key features of modern CFLs include:


The longevity of the lamp over conventional bulbs, instant striking resulting in no-flicker start up, excellent lumens per watt light output, and being very cost effective compared to other lighting.


Building regulations require that lamps are able to produce at least 55l/w (lumens per watt). Modern CFLs can now produce at least 85 to 90l/w, making them very attractive technically.


CFLs are exceptionally well suited to projects where downlighters are used, often as recessed fittings in suspended ceilings. Typical areas that these might be used would be entrance lobbies, corridors and toilet and service areas. In a high output configuration (say a typical 600mm x 600mm panel) they are also suitable for working areas like offices, classrooms and libraries.


We have also seen a significant increase in the use of CFLs in decorative areas like bars and restaurants, where configuration variants can offer special effects. For


By comparison, LED lighting has progressed enormously but can face a problem if high output is needed. A single colour LED light can produce up to 70 l/w but at this output level the white light can be very harsh, resulting in an


uncomfortable working environment for the users, and may even


result in eyestrain. The colour temperature can be adjusted to be “human-friendly”, but this results in a much-reduced output, requiring more fittings.


CFLs can be very cost effective, typically costing 25% to 50% less than the same size LED fitting. This results in much shorter payback periods, which is a real bonus for the cost conscious.


CFLs are an attractive option in many lighting applications. The key, as always, is to take advice from experts, such as our specialists at Fluorel, to get the right lighting for your application.

There are a number of reasons why CFLs should be considered as an option for many installations, especially where short payback periods would be a bonus.
