comparison between the fenix pd35 and tk22?

The pd35 as we know its 850Lumens ang lightweight , the tk22 is only 680Lumens
what is the advantage of the TK22 over the PD35?

Neither has a clear advantage over the other. It all comes down to use. 35 is more edc, 22 is more outdoors/hunting. 35 will flood with okay throw, and the 22 will throw and flood ok. 35 is pocketable, 22 is bulkier and is probably best carried in a holster. There are so many more factors, video reviews give the best representation of their capabilities and their limits. It's not always the highest lumen count that makes a flashlight great. UI, size, battery type, runtime, regulation type, build material, warranty, emitter, beam profile, price.

thank you for the output
