Well they are electronic so thought this would be the best forum...

Question about the new light bulbs that the Australian Government have said will be the only ones able to be used in the near future.

The current light fixture states do not exceed 60W. The new bulbs are 11W which is equivalent in light strength to a 60W. Therefore if I'm correct I could theoretically put a 60W "new" type of bulb which would be roughly equivalent to a 300 odd W bulb in brightness, yet not exceed the power/heat output for the said light fixture ?

Does that sound right ? I find the new sort of bulbs to be dimmer than the old style, and would like to up the wattage but am unsure if it would affect my fixtures.

Any clues ? No lights on no-ones home jokes either thanks

Yes that is correct - the sockets are designed to cope with the heat output of a 60-watt globe 240Volt x 1/4 Amp = 60 watt. The new globes draw less current. 25 watt [=125watt in old type] is the biggest I have seen though. I think heat output is proportional to the square of the current flow given a fixed resistance.

I agree they are just a bit more dim, 11W is more like 55W than 60W.

What....?

I agree....

It it isn't bright enough, change the globe.

I changed over to low energy bulbs over 10 years ago, takes a little getting used to but I'm still using the original bulbs...the old-fashioned type would have needed replacing several times over by now

If you don't like them they may well be redundant soon...

You can actually get 48 watt energy saver lamps but they are quite large in size.

They tend to give out a different type/colour of light than standard incandescent, thats why they appear duller.

Try getting one in a different colour - daylight or cool white, rather than the standard warm white.

Thanks Felch !!
