PEAK is a custom flashlight builder with the most popular configurations usually in stock. Most often, this means MAX output (Peak's #8). However, there are simply so many optional setups - and so many preferences involving the various combinations of features, batteries, uses, etc., - that it would take a rocket scientist to avoid disappointing or leading the customer astray through an automated ordering process. It would also be prohibitively expensive to inventory completed lights in more than a few variations.
But, within reason, you can have a light built to your specs. The various threads in CPF about Peak lights give a wealth of data on possibilities. My advice is to simply call, state your requirements and preferences, and ask whatever questions come to mind. Personal attention is there for the asking.
And thumbs up on the brass!
