Are there any commercialy-available low voltage lights which run cool?
Anything other than LEDs?


LEDs do not run cool. No form of lighting runs cool. HTH.


Low pressure sodium comes damn close - IIRC 80% efficient.
'normal' fluorescents are around 50%.

Not to mention that at low enough powers, most forms of lighting won't
heat up much.
