Keep in mind the Arc AAA is twice the price....

For our purposes, the Arc AAA has the following advantages:

• It's metal, not plastic.
• It's water proof (to 100ft) not water resistant.
• Uses AAA batteries (easier to find, replace)
• "Built like a tank". An Arc AAA can withstand abuse that will break a Photon. Try running over a Photon with you car... :-)

The Arc has always had a recessed LED to prevent the annoying side emission Doug's model is designed to prevent. The Arc lacks the different flashing modes and brightness controls. The Arc is switched on by twisting the head, not pressing a button.

Doug's model is a great compromise for the price. Like anything else, the more you pay (to a point) the more you get.
