Can someone tell me if there is much difference in running downlights as opposed to a regular light bulb in terms of energy usage and cost?
For example, on our house electrical plan there is one light for the sitting room, which we will replace with 4 downights. Does this mean we would be using 4X power or are downlights more economical and therefore be no different to running one regular say 100W globe?
Thanks,
Ray.
