The Fenix PD35R is the slim one. It runs an 18650 instead of the fatter 21700 most modern lights have moved to, and that is the reason to buy it: 1,700 lumens and a beam past 1,100 feet in a body that is thinner and lighter than anything in the PD36 or TK families. USB-C charging, a 1.5-meter drop rating, and IP68 waterproofing that covers the charging port too. Here is who it suits and who should size up.

Why the 18650 is a feature
The industry moved to 21700 cells for capacity, and the lights got fatter with them. The PD35R keeps the narrower 18650 and, with it, a tube that sits flat in a front pocket and rides on a belt without the bulk. 3,400 mAh is still enough for real runtime, and 1,700 lumens with an 1,100-foot beam is more than the daily jobs need. If you have picked up a 21700 light and put it back down because of the girth, this is the answer.
Charging
USB-C straight into the light, and the port is waterproof, which is the detail that separates this from cheaper direct-charge lights that lose their rating once the cover is off.
Durability
IP68 waterproof and a 1.5-meter drop rating.
Carrying it
This is the easiest Fenix to carry all day. Pocket clip, or a molded sheath from our flashlight sheath collection for the belt.
Who should buy it
Anyone who wants a serious light and a slim tube, or who already has 18650 cells from other gear. If you want maximum output and runtime and do not mind the diameter, the E35R or PD36 TAC on a 21700 are the step up.
