Jay I just got in your lens and swapped it out on my red burner unit for a nice increase in power. Output on my Laserbee 1 deluxe jumped from about 260mw to 318mw after 30secs so it looks like roughly another 22% increase with your lens for my red,very impressive indeed. Thanks again for an awesome quality lens just like the last one which put my PHR blu-ray over 200mw. Very nice work.
