Hi all,
in Wikipedia and many other places the efficiency of artificial light
sources, e.g. incandescent bulbs, is stated in per cent, and thus
treated as energy conversion efficiency. Here, the typical values for an
incandescent lamp (non-halogen, with a filament temperature of about
2700 K) are around 5% with 95% being wasted as "heat".
I am familiar with the definitions of luminous efficacy and efficiency,
both being well explained at [1]. However, according to this a light
bulb has a...
