The Muyan LED lights are nice little utility lights.
Compact and convenient in size and have great output.
The body of the Muyan light is made of aluminum with
what appears to be either a powder coat finish or very
strange anodize. Machining work is good, but a little
rough here and there. The head contains a silvered plate
with holes that the LEDs rest in. Around the middle
of the body is a knurled band for grip. The tailcap
has large chunky raised rectangles for grip. The tailcap
serves as a "tactical style" switch with a
rubber textured button for momentary operation of the
light.
The bezel consists of an array of 5mm LEDs soldered
to a printed circuit board. The LEDs rest inside the
metal plate on the front of the light. Since they sit
in recessed holes, most of the light is directed forward.
Output is in the form of a smooth central spot with
a slight spillbeam. The color temperature of the light
is fairly high with a slight bluish/purplish tint.
Beam at one meter at target center and at target edge
to show spillbeam.
Runtime Plot: Runtime to 50% starting output was 40
minutes and it appears to have a normal alkaline discharge
curve. It seems that there is no regulating circuitry
in the head or tailcap.
Runtime
completed with Rayovac batteries. More information on
runtime plots is available HERE.
The switch is a tactical style switch. Twist for constant
on, press on the rubber textured tailcap button for
momentary use.
There are O-rings at the connection points between
the body and both the tailcap and head. However I do
not know if the front of the bezel is sealed against
water entry. I'd give them a "splashable"
rating.
Ergonomics: The body is so short and stubby it is a
bit awkward to hold. Operating the switch in twist-on
mode with one hand is also a bit awkward due to its
diminutive length.
Size compared to a common 2AA aluminum light
For batteries, the light takes 3 AAA alkaline cells
in a carrier. Simply insert 3 cells with the negative
side of the battery against the coil springs in the
carriers. The result will be 2 batteries pointing in
one direction, and one pointing in the other in the
carrier. Remove the tailcap to change the batteries,
drop out the carrier, put new cells in the carrier and
replace. Batteries were not included.
What I Liked: Bright, Good battery life, Compact
What I Didn't Like: Short size
can be a little awkward in the hand.
Other Things I Noticed: Personally
I don't care for lights with battery carriers all that
much, but this isn't a showstopper or anything.
Conclusions: Simple, straightforward,
tough little design. Great for general use around the
house, car, camp, etc
