So I came across a "8 watt laser module", with a power supply, adapter and heat sync with fan, that was priced at only $76. Immediately I felt skeptical, since the cheapest I've been able to find a just raw 7 watt blue diode is around $80, and it was a Chinese seller. But since there were some positive reviews, I decided to take a risk and buy it. I assumed there was no way it was near 8 watts. I was partially mistaken.
I don't have a laser meter, but I estimate it's a least 4-5+ watts. This is because I put it up against laser pointers with a confirmed 5 watt output and did similar if not better for burning capabilities with similar focus settings. That said, the divergence is really bad. You can adjust the focus, but it spreads really fast. I think it may be the lens, cause even when I have it at the best focus for long range, I still see that the width of the beam near the lens is very small as if its focused.(Sorry my knowledge on lenses is a bit newbish)
I just wanted to share the link here cause regardless of the wattage rating being exaggerated, I still think this is a pretty awesome deal.
