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. There is a slightly granular texture
to the surface. The head contains a silver reflector
to catch the light from the LEDs and project it forward.
A polycarbonate lens covers the LEDs for protection.
Around the middle of the body is a knurled band for
grip. The tailcap is knurled for grip as well, and has
a hole on one side for lanyard attachment. A wrist lanyard
is included. On the end of the tailcap is the clickie
switch for operating the light.
The bezel consists of an array of 5mm LEDs soldered
to a printed circuit board. The LEDs protrude through
the silvered reflector which gathers the sidespill light
and helps project it forward.
Output is in the form of a smooth central spot with
a rayed corona and wide spillbeam. The color temperature
of the light is surprisingly nice and is closer to normal
sunlight white than many 5mm LED lights I've reviewed..
Beam at one meter at target center and at target edge
to show spillbeam.
Runtime Plot: Runtime to 50% starting output was 53
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 simple rubber covered clickie protruding
from the tailcap. Click once for on, once for off.
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 slightly tricky to hold comfortably,
and I have small hands. Large handed people may find
it a bit awkward. Switch operation is very easy with
one hand.
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
