RC40 vs TK75 '18

Both of these lights are in competition for the being the most powerful light Fenix has to date. Obviously, if you look at the lumen output, the RC40 of course wins with the 6000 lumens over the 5100 lumens that the TK75. But with both having different features, there can certainly be a winner depending on your use.

With the RC40, you have one purchase that will cover everything since the light will come with the battery and charger and all you need. With the TK75, you will need to purchase batteries separately, you are given the charging cable but will require a purchase of batteries. Both of these lights will be great for search and rescue, although, if your primary use will be search and rescue, then the RC40 will take the win with this one since this light has approximately the same throw distance of the TK75, but will have a much better beam in terms of a flood light. So instead of just the single dot you see, you will be able to see all around with the perfect combination of flood and spot. On the other hand, if you are needing to spot certain objects directly in front of you, then the TK75 will be the light for you with it's impressive beam throw.
