The Thorfire PF04 is in a Lightening Deal on Amazon until about 5:50 PM EDT Jun 11, 2018. The deal price plus a 20% coupon makes the final price $9.33.
I keep one of these in my first aid kit and my wife uses one for EDC. The mode increment (in lumens) is: 1 - 50 - 210. Typical Thorfire finish and quality. Makes a nice gift.
