Despite this HUGE close-up picture, the CR2 Ion is
absolutely tiny in size, as evidenced by the fact that
it runs on a single little CR2 lithium cell. However,
don't underestimate this torch based on it's stature!
It packs some serious output. Intended to be the paramount
Every Day Carry light for illumination connoisseurs,
this little photonic monster can produce a brilliant
wide beam when needed, and yet can also provide a very
soft and pleasing glow for close work in a dim environment.
Body: The body of the CR2 Ion is aluminum with
a Type-III hard coat anodize. The sample reviewed has
the "natural" color which is similar to Olive
Drab. Other color selections are available which include
black, red, green, blue, maroon, aluminum bronze, and
titanium . Four knurled bands surround the body for
grip and the head also sports a band of knurling. The
tailcap is designed so that the unit can stand on end
with a split-ring attached, and the split ring folds
over and into the tailcap area to keep it out of the
way if desired.
Inside, the body is coated with a corrosion
inhibitor (chemkote). This gives the inside a gold finish.
Bezel/Head: Believe it or not, you ar looking
at the Cree LED inside the aluminum reflector through
a glass lens installed above the reflector. This
is no photographic trick. The lens is coated on both
sides with an anti-reflective surface treatment and
the glass itself is of the "ultra-clear" variety.
The result is that unless there is dust or grime on
the lens, you'll swear that there is no lens on the
light at all. Truthfully, it's so invisible that I had
to rap my fingernail on it to check to see if they forgot
to install the lens - no kidding.
Sitting behind the lens is the aluminum
reflector and Cree XLamp LED. Further back in the head
is the fully regulated two-level constant current DC/DC
converter which provides steady output in both high
and low mode. Additionally a foam ring has been added
at the back of the head to help prevent battery rattle.
Output: The white light produced by the LED
is a very soft white with a practically unnoticeable
slight purplish tint.. The Cree LED and shape of the
reflector create a very smooth and even flood-like beam
with a slightly brighter center. This type of beam is
not designed to light distant targets, but is intended
for close range activities which would require illumination
of a large area close to the user. High mode is great
for searching for that lost something in the dark, while
low mode is great for reading. Also, since the Ion uses
a constant current regulator instead of a PWM regulator,
it does NOT have any annoying flicker when used in the
low output mode.

Runtime Plot: The CR2 Ion is a shining example
of solid output regulation. Practically flat output
is provided until the battery simply cannot provide
the energy needed to run the LED at the preset level.
Then comes a sharp plummet, indicating that it is time
to change the battery. This runtime test was completed
on "high" using the required tiny CR2 cell,
and supports the advertised 1½ hour "high"
runtime advertised by the manufacturer. Low output mode
is advertised as providing around 140 hours of light.
Note that CR2 cells only have 800mA capacity - that's
less energy storage capacity than a AAA cell - and yet
you get almost 1½ hours of bright light from
the unit. Absolutely amazing.
Runtime
completed with Duracell brand batteries. More information
on runtime plots is available HERE.
Switch: The head is the switch - simply twist
until it comes on in low mode, and continue twisting
if you want high mode. It takes about 3/4 of a turn
from when it turns on to switch from low to high.
Seals / Water Resistance: O-rings seal the light,
and it is advertised as "all weather" compatible.
I'd give it a "dunkable" rating. If it gets
wet, just dry it off.
Ergonomics: Minute! Teeny! Teensy-weensy! Dinky!
I think you get the point. It's very small, super lightweight,
and incredibly easy to use.
Size compared to a common 2AA aluminum light
Batteries: A single CR2 lithium cell powers
the light and a Battery Station CR2 cell is included.
I have been told that the Battery Station cells do not
perform quite as well as the big name brand cells, so
your runtime and output are going to be affected by
the cells you choose. I am planning on running a test
with Titanium CR2 cells to see how they perform, since
I have been very happy with the Titanium 123A cells.
Changing the battery is easy. Unscrew the head until
it comes off and drop the cell out. Put the new CR2
cell in negative first and reattach the head.
Accessories: Lanyards are available. The CR2
Ion is also available with a UV LED in place of the
standard white.
What I Liked: Everything.
What I Didn't Like: Nothing.
Picky Little Things: The split
ring on the tailcap can be difficult to remove from
and insert to it's "stowed" position. You
may have to fiddle with it a little.
Conclusions: The CR2 Ion is one
of the best of the best. An excellent light all the
way around. If using good quality cells, and using the
light as it is intended to be used, I doubt anyone would
be disappointed with this light. It's not a lighthouse
for picking out distant subjects, but rather a tiny
but powerful personal-use light for generally close-area
tasks. Unfortunately, quality of this sort does come
at a fairly high price, so be careful not to lose it!
