Looks a lot like the module made by Ramtronics.
From my website, comes the following text and photographs:
-----------------------------------------------------------------------------------------------------------------------
This module is made by
Ramtronics out of Taiwan.
The light it outputs is a slightly bluish white color, with an estimated color temperature of approximately 6,600°K.
Here is a photograph of the LED and driver assembly itself.
The metal base has two screw holes positioned approximately 1.35" apart.
This module is designed to be operated at 4.5 volts DC; if you exceed 6.0 volts DC, you might let all the magic smoke out of it and it will no longer function.
Forward current (If) is
391mA with a forward voltage (Vf) of
5.22 volts.
Measures
131,000mcd with a drive current of 391mA.
I am not equipped to measure beam angles, but this module appears to have a 5° to 8° beam. This is quite narrow, as LED beams go.
And here's a photograph of this module's beam approximately 5 feet away.
