Quick query re lighting costs

[nervous123]

Is the running cost of a floorstanding uplighter with a 90w bulb the same as that of a 90w bulb hanging from the ceiling?

Our dining room has a 90w bulb hanging from ceiling, and 8 x 50w downlights. I try to use downlights as little as possible, unless entertaining, to keep costs down. But the 90w bulb alone makes it quite gloomy.

90w is 90w wherever it is.

Ok, thanks.

A standard uplighter, using a 300w halogen, costs £45.

Am I correct that 2 hours usage a day would cost £52.50 per annum
i.e.
2 hours usage a day = 700 hours a year
@ 300w = 210,000w i.e. 210kW
x 25p = £52.50 ?

Correct.

Assuming your uplighter lamp is constrained by the length of the linear halogen, go for a 125W instead of the 300W - in the average domestic room you won't really notice any difference (might not be quite so hot!) but you'll better than halve the running cost.
