660nm is in the visible red spectrum, better to use a white light at that point. It also depends on the wattage of the output, regular laser pointer are in the mw range where did illumination (not collimated in to a laser beam) we are in the 1-3w range
I did a review here with a ebay link for what I brought. Contact the seller for customization option. I actually just ordered the 9 chips laser (supposed to be 15w) with 7 degree lens. It's in transit from China so I will update once I get it
6/3 Update So.... the 9 laser chips illuminator arrived today, it works and it is good! run lurk warm (not hot at all, i can hold forever) even in my chilly basement but since it will only be on at night with no Sun, that should not be an issue. Same great tight and bright as the 4 chips one...
