Advice On The Usage And Care Of Compact Fluorescent Lamps (CFLs)

Advice on the usage and care of Compact Fluorescent Lamps (CFLs)

Lumens

The brightness of an incandescent light bulb has always been expressed in Watts (e.g. 40W, 60W, 100W etc.) but Compact Fluorescent Lamps (CFLs), also known as energy saving lamps, use Lumens. A conventional incandescent bulb and a CFL light bulb may put out the same number of lumens, but the conventional bulb will consume three to five times the number of watts needed by the compact fluorescent. The table below shows the approximate relationship between the different bulb types in Watts and Lumens.
Incandescent Bulb (W)Approx CFL Equivalent(W)Rated luminous flux (Lumen)*
25W5W - 7W229 Lumen
40W7W - 9W432 Lumen
60W11W741 Lumen
75W15W970 Lumen
100W20W1398 Lumen
*Values quoted are for guidance only and are the minimum CFL lumens required to claim equivalence between CFL and incandescent lamps.

Handling

Always handle a light bulb by its base rather than the glass and never forcefully twist it into the socket.

What to do if a CFL breaks

Fluorescent light bulbs contain very small amounts of mercury, sealed inside the glass tubing. The likelihood of a bulb breakage causing health problems is extremely low, but nonetheless steps should be taken to limit any exposure to mercury, as well as to the risk of cuts from glass fragments. In the event of a breakage:

Disposal CFLs at the end of their life

All broken or used fluorescent tubes and CFLs must be taken to designated collection facilities at local authority civic amenity sites, where they will be removed for treatment and recycling. See www.recycle-more.co.uk to search for your local facility for the disposal of CFL bulbs, or contact your local council directly.
