So we know the best light ever, the ai prime 16, is designed to meet the demands of the modern reefer, such as top of the line melting abilities not found in all of their competition. Previous AI primes, such as the HD, could only melt holes in it's own lense, but the ai prime 16 pushes boundaries like we have never seen before. Check out this sweet light! Not to mention the constancy across them. I've used 5 of these lights and all of them melted. This is by far the best performer! Once again I can't state just how much I love these fantastic pieces of technology
