ARB INTENSITY AR32 LED SPOT LIGHT, EACH
(8.5" LENS DIAMETER / 10" OVERALL HEIGHT)
In 2009 ARB engineers started a development program to produce an
ARB driving light with a completely new design incorporating the latest
LED technologies. Unlike light bars that were growing in popularity, ARB
required a light that was compatible with current bull bar designs and
traditional driving light mounting points. The ARB light also needed to
be mounted in a legal fitment - and in many states, light bars are not.
Many ARB customers prefer a combination of a spot and spread
driving light due to the various driving conditions encountered in
general off-roading. Most LED light bars on the market are considered
great lights for slower off road driving where the ability to see great
distances is not so critical. For ARB's new light to compete with the
best the market can offer in Halogen and HID lighting, it needed to give
not only the broad flood beam associated with light bars but also a
spot beam with the ability to penetrate longer distances.
to the design was the need for the light to be robust and suited to the
conditions encountered off-road like the constant vibrations of
corrugated roads, animal strikes and the ability to be submersed. With
the general abuse that off-road driving can dish out, the light also
needed to be serviceable.
During the development stage, many
advances in LED and optics design meant that the LED array and circuitry
changed numerous times. With many tens of thousands to be invested in
tooling, this meant that the design of the light body needed to be
'future proofed' so that further advances in technology would not
The final design utilizes a pressure die cast
aluminum light body that acts as a heat sink where the removable LED
circuit board containing SMD LEDs mounts into the front face. The Hybrid
Optics (reflector & lens) are then located within a retaining bezel
and held in place by the polycarbonate lens. Any future advances in
technology therefore only require changes to the circuit board and
optics. Although SMD (surface mount) LEDs run very cool in comparison to
traditional resin encased LEDs, the circuitry and associated components
that power them get quite hot, requiring large heat sinks and cooling
fins with increased surface area to draw the heat away from the circuit
board. This required that the light body be manufactured from aluminum
but due to its round shape, a pressure cast aluminum body was preferable
over an alloy extrusion used in light bars.
With the light
assembly weighing close to 6.75 lbs, a mounting system was designed from
TIG welded 304 grade stainless steel to ensure integrity under the
harshest conditions. Stainless steel offers considerable strength over
With a requirement to handle extreme vibration,
the new light undertook Military Specification vibration testing on a
shaker table by an approved facility in Melbourne. Attached to an ARB
bull bar, the shaker table put both the light and bar through severe
testing, with both the light and bar mounts resisting fatigue and
passing the tests.
