Then not really. Wurkkos TD01 (FET) vs others from selfbuilt’s review:

Selfbuilt's Wurkkos TD01 Review

My latest review: Wurkkos TD01 This is Wurkkos’ new TIR-based heavy thrower, running off a single 21700 cell and the low profile SFT40 emitter. It’s a remarkably compact light for the beam it throws. Check out my full review for beamshot comparisons. But here’s a runtime teaser to get you started: [TD01-Med] Obviously that isn’t the sort of voltage-regulation you would like to see. But it is offered at at an incredible budget price for the beam. I’ll have more to say in the full review.

Ts22 and C8L have boost drivers (and slightly more efficient LEDs), Nitecore has exactly the same emitter and well regulated pbobably buck driver.

Sofirn SP40 vs. HS40, HS is basically an improved SP including the driver:

The larger the area the more efficient the driver is.
