[QUOTE="Gun$linger, post: 2173431, member: 11080"] I have a fairly big one that I made a stand for. It is a spot focus lense, mine will make about a 5/8 inch spot. This is better for firestarting or getting maximum heat in one spot. You could just the same place the target slighty closer and spread the heat out for cooking and the like. Its focal point is about 43 inches away. Use eye protection, the brightness and UV levels are blinding. Same for anyone watching. I havent got mine out since the middle of winter so Im looking foward to summer to really see what itll do. [/QUOTE]
