So, yesterday, I dropped my blue RPL and guess what, the diode no longer powers up. I know for sure because I've already removed the crystal set and the LED indicator lights red and no light at all, even through a camera. A friend of a friend was playing with my dog and ran into me from behind causing me to drop my laser on the concrete, so there's now a noticeable dent on the aluminum on the front of the laser, so warrantee is out of the question. I have experience and the safety equipment required to fix it myself, as it really isn't that hard. The crystal set is bolt-on as it is collimated and set perfectly as stand alone, four screws mount to the heat sink and base of the laser where the C-mount diode easily can be soldered and replaced. My problem is finding the correct diode. n light won't sell to anyone other then OEM suppliers, and there are a few on ebay that look good. I was thinking about this one but I don't want to go overboard either. And So I PMed a few of our LPF sells people, in hopes to find the one that will work best.
