I sent my brother in law around to see the night eater man. He has some of the best lights in the world. If you ever get the chance to check him out I would he is Victoria. They specialise in search lights. He will run you through the lights has has and you can compare he has a milo tin light that has to be seen to be believed. My brother in law took the 9" standard power beam and there was no comparision to the nighteater's. Night eater man advises it's all in the reflector that's what makes the difference.
The two biggest drawbacks with Night eater's are the price and the time it takes to get one.
