A word about 50W LED's equvalency

A project log for Diurnal Reef Controller for Lighting and Tides

Exactly the right lighting and tidal conditions have to occur to induce the spawning of corals (and other sea creatures).

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 ….

just weird autospacing from hackaday's blog editor ... your comment prompted me to try editing the entry again ... hope this looks better ... also, I edited out "consumes" and replaced it with "produces" .... which is what I meant to show with the chart ... thanks.
