Features

These low-voltage, flat-filament quartz halogen

lamps feature a small bulb shape and high

luminous intensity making them specially

suitable for use in compact and efficient

projection systems.

They offer a constant, high light output during

lamp lifetime. The excellent distortion-free

quartz bulb ensures optimal beam performance.

Lamps with prefocus base have a better-defined

position of the filament in the system allowing

lamp replacement without adjustment.

The lamps with the suffix XHP to the type

number have been optimised to give the

maximum light output while staying within the

IEC limits for these types by using random

filling gas.

Dimming of low voltage halogen lamps

Low voltage halogen lamps should not be

dimmed by more than 10% of their rated

voltage since this will result in a reduction in

life.

Standard tungsten filament lamps (with no

halogen filling), can be dimmed to zero volts,

resulting in vir tually endless life. However if

low voltage tungsten halogen lamps are

dimmed by more than 10%, the lamp will be

operating at too low a temperature and the

free halogens in the gas fill, will attack the

cooler parts of the tungsten filament i.e.

where the tungsten wire enters the quartz or

glass envelope.The wire at that point will then

be eroded and eventually will fail.

So if dimmed by 10% or more, low voltage

tungsten halogen lamps will not have an

extended life but are unlikely even to reach

their rated life.
