Ok I have a 300mw blues pointer I got from a friend worked great till the diode got wet now it still emits light but the beam will not focus and it really sucks. I figured I would fix it problem 1 there is no name on it I contacted the person it was bought from and they told me it comes from the builder? Bullshit so then I look up the driver chip numbers easy to find no problems there.. the problems is that the actual diode seams to be pressed in, I figured that so I thought I would look up new diode to try and get some idea of what I was looking at. So I néed advice on how to replace it and from where to find part
