Using a chart from Wikipedia (link here), I created the following chart in order to get some equivalency between bulbs and LED illumination:
The wiki chart only goes up to 300 W (incandescent), so I curve fit the data to get some idea of higher values. Since the polynomial curve fits show a round off beyond 300, I use the linear fit. According to that, a 50 Watt LED produces the same radiant power as a 350 Watt incandescent bulb – that should be 106 W for compact fluorescent bulbs. Of course, only the linear curve fit gets to 50W ….
