The Australian Government wants to ban the use of incandescent lamps. The German Minister for the Environment approves and is thinking of taking up the idea. Replacing an incandescent bulb by a compact fluorescent lamp (CFL) does indeed save around 75 % of the energy consumed. But how feasible is it to try and replace all existing incandescents by CFLs? Are today’s CFLs up to the job, or are technical improvements still required? And what about the alternatives? Are there any other light sources of equally high-efficiency as CFLs but without the disadvantages?

Policy Status: In force
In August 2005, Natural Resources Canada proposed amendments to Canadian efficiency standards for fluorescent lamp ballasts that would harmonize Canadian ballasts with the efficiency requirements of the US Energy Star Program. In addition to this harmonization objective, NRCan had proposed several efficiency upgrades in March 2005, including:
- repealing the effective date requiring all ballasts to comply with the regulations regardless of date of manufacture
- addressing the BEF for ballasts operating with energy saving lamps
- revising the cold temperature exclusion
- adding an exclusion for dimming ballasts.

Modern dimmable electronic ballasts provide excellent versatility for lighting scenes in conference rooms, theatres and the like where magnetic ballasts cannot compete, although a new technique to make magnetic ballasts dimmable is presently under development in Canada but not yet available on the market (for news on this see here).

There is active fluorescent lighting and apparent fluorescent lighting. Often the so-called Linestra lamps are confused with fluorescent lighting tubes by laymen - and not only by laymen - because of their tubular design. Albeit, a Linestra lamp is an incandescent lamp, and one with a very poor efficiency on top of this! The efficacy is only half as good as that of a general purpose incandescent light bulb of comparable power rating.

The IEC has standards covering both a flickermeter and a flicker definition. These documents have been adopted in Europe by the CENELEC as EN norms. Limits of the severity of flicker caused by voltage fluctuations are defined in Europe by the standard CENELEC EN 50160.
