Halogen IR ™ DEQ
Double Ended Linear Halogen-IRTM Lamps
with R7s cap 225W, 375W, 900W
Description
The quartz bulb is coated with a patented IR reflective
thin film which results in the energy saving benefits
shown below. The use of standard R7s caps allows
direct replacement into standard fittings. Lamps are
offered in both 230 and 240V alternatives.
Halogen-IR™ Technology
In standard incandescent and halogen lamps
approximately 76% of the input energy is lost as heat
radiation, whilst only 8% is converted to useful light
(the rest is lost in the area of the filament).
The Halogen-IRTM thin film, consisting of multiple
layers of very durable, thin, interference films, reflects
much of the heat back onto the lamp filament, while
allowing the visible light to pass through. This
increases the filament temperature which allows it to
give off more visible light for the same input power.
This increase in efficacy can be used to reduce the
required energy input for the same light output, to
increase the life of the lamp, or a combination of both.
Benefits
• 25-40% energy savings compared to the light
output of their standard equivalents
• excellent lumen maintenance
• stable colour temperature
•dimmable

Tungsten Halogen Principle
The tungsten filament is enclosed in an inert gas filled
quartz bulb, together with a controlled quantity of
halogen. At the operating temperature some tungsten
vapourizes and migrates to the cooler areas of the bulb
wall where, before it can be deposited, it combines with
the halogen to form a tungsten halide. This circulates
until it comes near the filament where the halide
dissociates and deposits the tungsten back on the
filament. This cycle continues throughout the operating
life of the lamp.
As the bulb wall remains clean the bulb size can be
reduced considerably by the use of quartz which can
withstand the high wall temperatures.
The small bulb and strong materials withstand much
higher working pressures and the increased gas density.
This reduces filament evaporation, thus offering
increased performance either as more light or longer
life.
Light, Life & Voltage
For any particular lamp, the light output and life
depend upon the voltage at which a lamp is operated.
For instance, as approximations, the light output varies
as the 3.6th power of the voltage and the life varies
inversely as the 12th power of the voltage. The Chart
and Tables below illustrate the effects of overvoltage or
undervoltage applied to lamp on its current, life and
light output. The values given (except for long life
lamps) are reasonably valid between 95% and 110%
rated volts.
Beyond this range the indicated characteristics may not
be realised because of the increasing influence of
factors which cannot be incorporated into the chart.
The chart applies only to D.C. or sine-wave A.C.
current. The data may differ, particularly for lamp
operation on half-wave rectified voltage,
semiconductor dimming devices ofconstant operation.
Operation and Maintenance
• Switch off mains supply before installing/removing
lamp.
• A suitable HBC fuse is essential in circuit.
• Observe temperature tolerances — pinch seal, max.
350oC, bulb wall min. 250oC.
• Lamps should be free from contamination,
including finger marks, before lamp is operated.
Lamps can be cleaned with a soft cloth moistened
with alcohol.
• Good condition of lampholder contacts is essential.
• Bulb wall temperatures are high and therefore lamps
should not be operated in flammable atmospheres
unless enclosed in suitably rated luminaires.
• Ensure lamp is cool before removing.
IEC Standards
GE tungsten halogen lamps comply with the following
international and British Standards where applicable:
• IEC 60432-3 Tungsten Halogen Lamps Safety Standard
• IEC 60357 & BS 1075 —Tungsten Halogen Lamps,
• IEC 60061 & BS 51001— Lamp Caps & Holders.
