<div>Jon, Steve</div><div>Not sure if this is up your alley, but here is a picture of a 10,000L oil filled light that is very easy to build and inexpensive. I have tested this light to 1,500 psi. This is a short version of the 24,000 L light on Gamma that is just amazing. The light consists of a off road light bar circuit board that slides tightly into an acrylic tube with rubber ends to act as bellows.</div><div>Hank</div><div><br></div>
