Running cost LV halogen

I have a dumb (probably) question. If I have a room with 9 LV Halogens running at 50% (I am using this figure as an example), does this mean that I am consuming half of the power (roughly) as opposed to running them at 100% (using CBUS or standard installation)?????

I am at the crossroads in my building phase and need to decide if I can squeeze CBUS into the overblown budget (I feel like Kevin Rudd trying to sell the "temporary" deficit to Malcolm Turnbull.....)

 

Measured Lighting levels, power consumption, perceived illumination, etc is quite an involved topic with plenty of variables and plenty of subjectivity thrown into the mix as well.

In simple terms, when the input is at 50% the actual power being used will be somewhere around 75% of the maximum power consumption, give or take about 10%.

 

Thanks - I was optimistically hoping that it would be as simple as that. I was trying to find out whether my electricity bill would work out more expensive or less between a CBUS install and traditional install. I'm hoping less obviously, but the builder was installing the CFL downlights (Megaman) and from what I've read they're not really suitable - even the dimmerable range. I didn't want to fill the house with Halogen LV downlights, then install CBUS and then have an astronomical power bill each 1/4.

 

Having C-bus or not does not effect your power bill in any way shape or form. As I understand it you were talking about light dimming (using C-bus), which can be done just as easily (and cheaper) using a 'traditional' install as you put it.
