ARB Intensity AR32 9.5" LED Driving Light

Description
These new Intensity LED lamps from ARB utilize a pressure die cast aluminum lightweight body that also acts as a heat sink where the removable LED circuit board containing 32 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 super strong polycarbonate lens. 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. These amazing lights feature a 6500k or Kelvin color with an output of 8200 lumens. With a life span of 50,000+ hours and an IP68 Certification you will not find a better and more powerful auxiliary light. Lights are sold each.
Details

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. They also needed to be a legal fitment which, 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.

Integral 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 require re-tooling.

The final design utilises a pressure die cast aluminium 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 aluminium but due to its
round shape, a pressure cast aluminium 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 other designs and
with a requirement to handle vibration, prototypes of 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 test.

Further testing was then carried out to ensure the light was waterproof, with the light achieving a rating of IP68. IP ratings
are an international code giving an Ingress Protection Rating and classifies in this case the level of protection given to an
electrical enclosure. The ‘6’ in the code relates to solid particle protection and is the highest rating: Dust tight-No ingress of
dust; complete protection against contact. The ‘8’ relates to liquid ingress protection and is also the highest rating: Immersion
beyond 3.25 ft. - The equipment is suitable for continuous immersion in water under conditions which shall be specified by
the manufacturer.

To finish the outer surfaces of the light to ensure durability under the harshest conditions, the aluminium body is finished in a
textured polyester powder coat that passes the ISO7253 3000 hour salt spray test. The lens retaining bezel is finished in a
UV resistant red two pack automotive paint. This combined with the 304 stainless steel mount makes the ARB Intensity light
extremely corrosion resistant.

Performance of the light can only be described as intense and hence where it derives the name ‘ARB Intensity’. At 6500K, the
color temperature of the LEDs is as close to daylight as possible and with 32 LED’s per light producing a broad beam, even
on spot versions the lights illuminate everything in the driver’s forward field of view. No longer does the driver find themselves
straining to see beyond the edge of the beam, hence reducing fatigue.

ARB Intensity LED lights are sold separately as either a spot or flood beam. A new wiring loom has been developed that
includes waterproof Deutsch DT-06 connectors and is available by ordering P/No 3500520.

Flood Beam

Spot Beam

Cooling:
The pressure cast aluminium housing acts as a heat sink to draw heat generated from the electronics away from the LED array, thus increasing efficiency and life of the LEDs. Cooling fins cast into the rear of the housing increase the cooling surface area of the light body by a massive 200%.

Security:
Each light has a cap screw pivot bolt with tamper proof TORX® security fastners used on the adjuster nut for improved security.
The main mounting bolt has a 12 x 1.75 thread which accepts the traditional style security nut and Key as used with IPF lights (available separately).

Electronics:
The heart of the light is its electronics. Using SMD type Osram LEDs for increased efficiency and brightness, the circuit board sits deep within the light body,offering protection to the advanced circuitry while mounting directly to the cast housing for optimum heat transfer and cooling efficiency.

Optics:
The advanced Patent design optics incorporate both a reflector and lens to control the light emitted from the LED with 93% efficiency.

Designed to offer different light projection patterns, they are the only components that differ between the flood and spot model lights with the flood offering 20° spread and spot a 10° beam.

Advanced Sealing:
A unique molded rubber seal sits between the polycarbonate lens and cast aluminium body, creating a watertight and dust proof seal to allow the light to achieve an IP68 rating - meaning complete protection against dust ingress and submersion beyond 9.75 ft.

To allow expansion of the heated air within the light and suction caused by rapid cooling if immersed, the light is fitted with a Gore® membrane breather which allows the light to breathe without moisture ingress.

Clear Cover:
Manufactured from 3.5mm injection molded polycarbonate and hard coated for scratch resistance, the clear cover is standard fitment providing the ultimate protection from impacts. Being 100% optically clear, it does not effect light output performance.

A warning appears on the outer rim of the cover stating - ‘Warning: High output light source. Do not look directly into optics when light is operating’.

Cover Attachment:
The unique body design features a slotted recess for the clear covers to positively attach to the body and prevent cover rotation. To remove the cover, simply place fingers behind the cover retaining tags and lever outwards while pulling the tangs forward.
