=Basics=
*This page lists the Luminous Efficacy of various light sources
*Main units are
** [[Lumen]]s per [[Watt]]
**and Percent Effeciency

=Carbon Air Arc=
*~2-7 Lm/W
*~0.29-1% efficiency
*VERY obsolete
*No longer in active development

=Incandescent Lights=
*~5-25 Lm/W
*0.7-3.5% efficiency
*Considered Obsolete in most use cases
*No longer in active development

=Gas Discharge=
*~30-78 Lm/W
*~4.4-11.4%
*Still common in projector lamps and vehicle headlight, although they are being phased out for LED
*No longer in active development

=Florescence=
*~36-104.2 Lm/W
*~9-15.62%
*Still common, but are being slowly phased out by led in most applications
*No longer in active development

=Gas Discharge=
*~2-200 Lm/W
*~0.3-29%
*Being replaced by either LEDs, Laser Diodes, or Sulfur Lamps depending on application

=Electrodeless Gas Discharge / Sulfur Lamps=
*Still barely developed, so may be higher in the future
*~100 Lm/W
*~15%
*Also for the numbers there are not many in this category yet, so little averaging, also the current sources are almost SOLELY very high output
*May never be fully developed, future uncertain

=LED=
*~102-300 Lm/W
*~20.3-43.9 Lm/W
*Granted these scale from pixels to ~3cm chips and not much larger
*Also this technology is mostly developed, but new phosphors etc may increase the efficacy slightly
*Technology is being actively developed
