I was surfing a website on Glock handguns and came across a posting trying to sell "Digi-light" brand tactical lights. It is not LED, it takes (2) CR123 batteries. It looks like a Surefire knock-off. It was selling for $27.00. Seller claims it normally retails for $30.00. Seller also claims they are giving "special" price to get feeler for product before it is introduced in the U.S. This combined w/ fact the price is low leads me to believe these are SF knockoffs from China. Google search for the company was negative.
