Product information

The name says it all: With their slender forms, the flashlights in the Walther Pro Slim Line series are always ready for use. In 2017 the SL66r even won the Red Dot Award. This lightweight flashlight weighs a mere 85 grams and is only 140 millimeters long, but it delivers a full 950 lumens. Like all Walther Pro flashlights, the SL66r has output settings of 100, 40 and 10 percent plus a strobe mode for defense against attackers. The Multi Battery System is a model of flexibility: The flashlight comes with a rechargeable ICR18650 lithium-ion battery but can also take CR123 batteries or inexpensive AAA batteries. Recharging accessories are provided as standard. All of this makes this flashlight, which is watertight with a rating of IPX8, a highly versatile companion for outdoor use.

The Red Dot Award is one of the world’s largest design competitions. In 1955, a jury convened for the first time to assess the best designs of the day. Ever since, the sought-after Red Dot award has been the revered international seal of outstanding design quality. In order to appraise the diversity in the field of design in a professional manner, the award breaks down into three disciplines: the Red Dot Award: Product Design, Red Dot Award: Communication Design and Red Dot Award: Design Concept. Each competition is organised once every year.
