<div>Jon,</div><div>I have noticed looking at pictures from other subs that the spot light, lighting is spotty. There are dark areas in the images. This is an image taken a week ago at close to 300 feet in the darkest water I have ever been in. Notice how even the lighting is and the light goes beyond the camera view. You can make this light for a couple hundred bucks maybe 300 with hand tools. I have had this light for a long time with lots of dives even to 435 feet with zero issues. I tested one that I made for a friend to over 1,000 psi and another for Scott to over 3000 psi.</div><div>Hank</div><div><br></div>
