Knog Blinder Bicycle Light, X Pattern, Rear, Black

The Knog Blinder rear light in the X pattern uses chip-on-board (COB) LEDs. Knog's official specification is a 100-lumen maximum. (A BTI bullet also mentions 200 lumens; that figure is not used here, because the official Knog product page and its technical table both state 100 lumens.) This listing is the black, rear, X model, Knog part 12290.

There are eight lighting modes. On the official US page, the feature list gives up to 2.5 hours in High Steady and up to 60 hours in Eco-Flash, while the technical table on the same page lists Max Steady at 2.5 hours and Eco-Flash at 55 hours. The US page also lists visibility out to 1,500 ft. Charging is through an integrated USB-A plug, with a 4-hour charge time and no separate cable required. Knog rates the light IP67 and gives a weight of 34 g (1.2 oz). Housing size is 43 mm high, 43 mm wide, and 46 mm long. A low-battery indicator is included. Straps are medical-grade silicone and fit seat posts 22-32 mm and larger. The US page lists an operating range of -4 to 122°F.
