I just learned that Brinyte supplies Securitylng with many of their dive lights. So Securitylng is the customer and puts their name on some of Brinyte's dive lights, as well as others like Trustfire etc.
This is just a tour of some of Securitylng's dive lights. Lots of options.
See hyperlinks for descriptions.
