Fenix PD35R ACE Multi-Mode Tactical Flashlight

Same PD35 platform, two different charging philosophies and two different size classes. PD35 V3.0 is the slimmer, lighter tube — 134 mm long, 83.5 g bare — running 1,700 lumens to 357 m on the included ARB-L18-2600U cell. The “U” cell has a USB port built into the battery itself, so you unscrew the cell and plug it straight into any USB source — no external charger, no charging port on the light, and 2×CR123A remains a backup option. PD35R ACE is the bigger-capacity model — 140.5 mm, 145 g with battery — pushing 2,000 lumens to 380 m on a 4,000 mAh ARB-L18-4000, with USB-C charging built into the light itself and programmable output steps. Pick V3.0 if you want the slimmer EDC tube and like topping up spare cells individually; pick PD35R ACE if you want more output, longer runtime, and to charge the whole light through one cable.

Same ACE family, same hybrid control scheme (tactical tail switch + neck-mounted side switch), just two different size and power classes. PD35R ACE is the 18650-format EDC model — 140.5 mm, 145 g, 2,000 lumens to 380 m on a 4,000 mAh ARB-L18-4000 cell. PD36R ACE is the 21700-format big-brother — 146 mm and 181.6 g, 3,000 lumens to 415 m on a 5,000 mAh ARB-L21-5000 V2.0 cell. Both charge via hidden USB-C in the light neck and share the same tail-plus-side-switch philosophy. Pick PD35R ACE if you want a slimmer EDC-friendly pocket tube; pick PD36R ACE if you want more output, longer runtime, and more throw — the 21700 cell is the only real size penalty.
