Light Type: LED
Light Class: General Use / Etc.

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
