I ordered two of these modules from DX on August 1st. They did not ship these until October 15th, and I received them October 26th. Despite nearly no padding around them in the brown envelope they came in, both arrived in perfect working order. As I recently purchased a Laserbee LPM, I used it to measure the performance of these modules.
The first module output 75mW to start and gradually rose in power as the module warmed up. Output settled at 142mW, taking 90 seconds to get there. Leaving the module on a little longer let it fluctuate between 138 and 145mW.
The second module output rose steadily and rapidly over 30 seconds, reaching a peak of 146mW and settling back to 122mW.
First photo shows the module unscrewed in half showing the crystal mount.
Next two photos show top and bottom of module.
The last photo shows a module, a module in a brass host (1 x 10440), and a DX dilda for size comparison.
I wasn't expecting to get a full 200mW of power for the price of these modules. I am surprised that they exceed 100mw. They are a little better than I was expecting. To put one in a host, the black wire can be unsoldered and replaced by a spring, negative of battery goes to this spring. The red wire is not needed and can be unsoldered or cut off. The brass is the positive connection. A trace on the board goes from the red wire to the case lead of the diode. Positive of battery would touch the tailcap. As long as the brass body makes good electrical contact with the host everything will work. In the host above, the module is a gentle press fit into the host. Good contact and good heat transfer. For anyone still interested in these, beware of the slow processing of DX ...
