Could anyboby explain why the 12v 50w halogen lamps I have in my kitchen
appear brighter than the 240v 50w halogen Par 20 lamps I have fitted in
the
lounge?

Higher colour value. Whiter light. Dichrioc prismatic diffusion.



Actually its simpler:

Bigger filament=runs hotter without melting = higher colour temperature=
whiter light.
