@jwcph@edavies@yngmar this remains true today. Or at least, wherever you can still buy general purpose incandescent light bulbs.
In the video I show a 40 w appliance bulb and a 40 watt chandelier bulb. They use identical amounts of power, but the appliance bulb was rated for 2,500 hours rather than a thousand and was much dimmer.
Therefore, if you needed more light, you had to burn more of those bulbs and would spend much more money on electricity.
