Think those compact fluorescent bulbs are not as bright as the old-style lights they replaced? You are probably not imagining it. A guide to the amount of light given by a CFL bulb is given on its box as a comparison to the wattage of an incandescent bulb. But the European Commission says in a FAQ document this can be misleading.

“Currently, exaggerated claims are often made on the packaging about the light output of compact fluorescent lamps – for example that an 11-12-watt compact fluorescent lamp would be the equivalent of a 60-watt incandescent, which is not true.”

Brightness varies as conditions change. “A compact fluorescent light is designed to provide maximum light output at 25C, and when it gets hotter or colder than that, its brightness can be reduced. If your bulb is in a recessed fixture in the ceiling, and it gets warm, you might see a 10-20% reduction in its light output.”

And studies show CFL bulbs can get 20% dimmer over time.

New European regulations expected next year mean manufacturers will have to display lumens – a measure of light output – more prominently than wattage on bulb packaging.
