Why do energy-saving lightbulbs take time to reach full brightness?

« on: 01/04/2012 09:41:02 »

Oliver Clark asked the Naked Scientists:

Hi Chris,

Great Show

Why do energy saving lightbulbs take so long to get to a bright light and why is this level still dimmer?

Oliver Clark (Aged 12)

What do you think?
