Lightbulb myth

I see on mythbusters they are seeing if its better to leave a light on all day, or swicth it off & on when you need it!. (due the to energy surge on start up)

Well the start up cost equates to the following times!

LEDs - 0.33 sec

Halogen - 0.51 sec

Normal bulb - 0.36 sec

Floresenent tube - 23.3 sec

Energy saving bulb - 0.02 sec

they also tested to see if turning them on & off shortens the life of the bulb.....

5 years of switching on & off for the average bulb!

I always thought those florienscneenntent tubes used alot more.

Being serious for a moment, I cannot believe that the energy saving bulb uses less energy starting than a standard bulb, they are to all intents and purposes a mini fluorescent tube with in built starter.

the energy bulb takes longer to fully opporate than a standard bulb which opporates to full power right away .

but the fact its going to run on 25% of the wattage means it can tripple consumption on start up and still be less than the equivilent "normal" bulb

Ive just become the proud owner of my first ever energy saving lightbulb - cant say Im impressed. You switch it on and its like a 15w bulb for ages and then it manages to get a little brighter up to 75w in total. But why does it take so long to reach its peak? Could do with installing a timer on the switch so it comes on half an hour before I get up. Or I might just leave it on 24/7 cos its energy saving......
