Extra-low voltage lamp
According to BRE’s The essential guide to retail lighting, extra-low voltage lamps are:
‘Small tungsten halogen lamps producing two or three times the light output of conventional filament lamps. Normally powered from a separate 12 V source. Apart from increased efficiency and lamp life, the heating effect is lower, which is preferable for display lighting.’
