Yeah what percentage were you pushing i have 3x 16hd's with no issue , this usually comes from people buying the cheapest light they can then overdriving the light to get the most light they can out of this tiny thin light, its not a 500$ light for a reason, should it melt no, but after you saw the first and second one melt, when does it become insanity? Guaranteed these lights that are melting are over pushed and maxed out.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
