Hey everyone, here’s another build I deemed review worthy because I like it so much:
Since I had a low powered 450nm diode lying around, and been thinking of doing a fairly small build, I decided to order some supplies and go at it.
What I used for this build was:
Stainless Steel CR2 kit from Jayrob
V5 FlexDrive
Osram PL450B diode from DTR
1 x RCR2 Battery
As per usual, my parts arrived in a timely fashion form both DTR and Jayrob, and I already had the FlexDrive. The first thing to do was to connect the FlexDrive up to my test load and check my current. The current I decided on was 310mA, and the closest I could get was 308mA, which I was happy with.
The next part was to install the diode in the module and connect it to both the battery PCB as well as the driver. The CR2 kit came with the original flashlight driver, which I had to remove all of the original components and check the connections with my DMM. After playing around with the host, I found it worked best to mount my FlexDrive directly to the diode, while using short leads on the other end from the driver to the battery contact.
To prevent any shorts, I also wrapped the driver with a small piece of electrical tape.
Although I don’t have any pictures of this part of the assembly, it was a little tough to screw in the pill which keeping the heatsink stationary with respect to the pill from keeping any wires getting tangled. To help this, and to make things secure, thermal adhesive was used between the pill and the heatsink, as well as a little arctic silver between the host the heatsink. This was to ensure that the whole host acts as a heatsink.
Here is the whole kit before final assembly
The host is very small, and I love it, it is really heavy for its size also, which feels very solid. My only complaint here is that it gets fingerprints on it easily, but that’s what to expect with a mirror finish. Overall this is probably my favorite laser, it is fairly low-powered (but still dangerous), small enough to put in my pocket or even on a keychain, and super bright.
Now time for the LPM tests. I tested this laser with both a 3-element glass lens and with a G2 lens from DTR. Between the two lenses there is just under a 20% increase in power.
Finally a couple beam shots
Thanks for reading!
