Laser Devices Inc. MK3 Battle Light A compact and effective
lighting accessory for professional use.
By: Sal Palma
Laser Devices Inc is located in Monterey, CA and its one of a
few premier suppliers of multi-spectral weapon mounted laser and
lighting accessories to law enforcement, military, state and
federal agencies. The company is a global supplier with an
established reputation for durable quality products and support.
While at the 2014 Shot Show, I had the opportunity to meet with a
representative who took me through their new product lineup. I was
intimately familiar with the LDI DBAL and a number of their
accessories, but I was intrigued by the MK3 Battle Light. I think
it was the combination of packaging and the arrangement of its IR
LEDs. I knew that a veritable cornucopia of white light and IR
illuminators existed in the market, but quite frankly few have
performed well. Certainly not well enough to constitute
professional grade equipment, so I was anxious for a test run of
LDIs MK3Battle Light.There are numerous reasons to buy LDI products
but one that I find creates a strong business case is the
consistency of the human interface across their entire military and
civilian line. When you purchase LDI you get a weapon accessory
that is consistently reliable, robust and a consistent user
interface, all important consideration in professional use. The MK3
Battle Light follows suit. The packaging is quite extraordinary,
and the all-aluminum housing looks to be more the product of the
Czech cubist architect Josef Gor. Its unquestionably elegant with a
large bezel measuring ~ 1.54 inches. However, in spite of its large
bezel, the housing or body geometry allows the light to sit closely
to the weapon and mounting rail. Ive encountered very avant garde
designs, of similarly sized bezels, that protrude so far beyond the
weapon as to make them a royal pain in the butt to use; not to
mention vulnerable to accidental impact. Those designs adhere to
the misguided precept that barrel shadow is an intolerable evil, so
lets get that light out and away from the weapon as far as
possible. Allegedly, barrel shadow creates a blind spot that keeps
you from detecting bad guys! Really? Put down the You Tube fellas!
Ive even seen people adding risers to a light mount; I wonder what
theyll do when they hang a suppressor off their carbine. I guess
you can always use 200 mph tape and mount it to the muzzle device.
Well, Ill keep the barrel shadow and opt for the compactness and
mounting of the MK3.LDIs new Battle Light uses the same quick
attach / detach HT mount that youll find across the companys entire
line of rail attached accessories, for example the DBAL. The HT
mount works extremely well with any Picatinny mounting rail; yet is
easy enough to operate, unlike some of the cam lever mounts in use
today that require considerable force to operate.Earlier, I spoke
of consistency in the user interface, which is a huge hot button
for me. As I looked at the rear of the light there was no need for
clarification or acclimation, its user interface is consistent with
LDIs other products. The back plane contains a rotary switch, shown
in the OFF position. The selector provides the operator with access
to all modes of operation. They consist of LO-IR, HI-IR, LO-VIS,
HI-VIS and MOD (an 8 KHz strobe).At the 1 oclock position, from the
operators viewpoint, youll find an LED that lights green when the
MK3 is in use, and flashes to indicate a battery low condition. In
summary, if youve used an LDI DBAL, ITAL, EOLAD youll feel right at
home with the MK3 Battle Light. The back plane also contains the
pressure switch jack and the activation button designated as FIRE.
Pressing the FIRE button once gives you momentary IR illumination,
visible light or strobe. A double tap places the light in constant
on mode. LDI included a 5 min constant time-out, which is a very
nice feature to have. The FIRE button is covered with a heavy duty
rubber boot and has excellent tactile. It is also placed so that
its easily accessible with the support hand. One final observation
before moving on to performance is the quality of LDIs pressure
pads. LDI makes one of the best pressure pads Ive ever used; they
are durable and feel great to the touch. Shifting gears into
performanceThe MK3 Battle Light is impressive; both visible and IR
illumination have Lo and Hi outputs. The IR illuminator operates in
the 850nm wavelength so its fully compatible with night vision
goggles (NVG) and weapon sights. In LO-IR (
