Halogen incandescent lamps
– Mains voltage low voltage
– Service life and luminous efficiency better
than incandescent lamps
– Dimmable
– Brilliant light
– Excellent colour rendering
– Use: retail and domestic areas,
hospitality and decorative applications
Functional description
Current flows through filament and heats
it exactly the same way incan-
descent lamp. This why these lamps relea
se
relatively large amounts heat.
Low-voltage lamps are very compact and
therefore ideally suitable for directing light
precisely, but they need transformer. The halogen
cycle boosts the efficiency and prolongs the
service life these lamps compared with
conventional incandescent lamps
