This little plastic LED light runs on 2 coin cell batteries
which power a single exposed 5mm LED. Activation is
by pressing on the large panel on top of the light for
momentary operation or by clicking the little protected
switch with your fingernail for constant-on use. The
entire body has a slightly granular texture. Extremely
small and lightweight, and inexpensive, these are a
fine addition to your keychain. Great giveaway gifts
as well. This particular unit uses one of the new 35K
LEDs which is significantly brighter than the previous
5mm LEDs.
Output description: Output is in the form of a rather
bluish tinted spot beam with a wide spillbeam. There
are some slight artifacts in the beam, but nothing serious.
Since the color temperature is so high and it leans
heavily toward the blue end of the spectrum, color rendition
of red and orange objects is not that great.
Beam at one meter at target center.
Runtime Plot: A runtime plot will not be completed
for this light.
Switch description: There is a large flat pad on one
side of the light. Press to activate the light in momentary
mode. There is also a very tiny clear click switch near the front
of the light which is protected by a protrusion. Hook the
switch with your fingernail and click it backwards for constant-on.
There is no texture on the large squeeze switch, but the tiny
click switch has 3 ridges to aid in grip.
Seals / Water Resistance: The light has no seals. The tight
fit of the parts will keep some water out, but I would
recommend it be kept dry.
Ergonomics: So lightweight it almost disappears in
a puff of quantum physics. Easy to use the click switch
provided you have fingernails long enough. Otherwise
you are stuck with momentary operation only.
Size compared to a common 2AA aluminum light
Batteries: 2 x 2016 lithium coin cells. Remove 4 screws
on back to change out the batteries. Be careful to observe
how the light is assembled if you take it apart to change
the batteries. There are a couple of small parts that will
fall out if your are not cautious.
Accessories: Split ring with swivel for keychain attachment included.
