Ok, my mistake. It was late (3:00AM) and I was at work. It's Dive Rite that uses the chrome plated brass type fittings. When I told Sealcon what I was going to do with their strain reliefe fittings the rep told me that they supplied Dive Rite with the fittings they used on their lights.
DNAXdiver once bubbled...
halcyon doesnt use a chrome plated brass fitting nor a sealcon they use a stainless version of the 50¢ hardware store brass tubing fitting and oring gland that they used to use and that most homebuilder and AUL use
however they didnt swtich to ss because anyting was wrong with the brass they just wanted something prettier
