This will be just pure measurement data for the Klarus G30. For general info and runtime tests check out Budda’s great review at CPF.
My G30 was purchased from Everbuying for $54. The light is currently on sale for $52 at Gearbest. For the price, it’s a steal.
For BLF, there’s a coupon code available from M4D M4X. PM him for a good price
For comparison, I’ve also posted some data from my Nitecore EC4SW review that also uses the Cree MT-G2 emitter, although it runs on 2 18650s instead of 3 like the Klarus.
Beam and CCT. Very smooth transition from hotspot to spill.
The whole beam has a tint close to the black body radiation line.
Tint in different brightness modes stays quite consistent.
Comparison to the Nitecore EC4SW tint. This graph is zoomed in so the difference is actually very small and in practice almost impossible to discern.
The color rendering and CCT are also very comparable for the Klarus and Nitecore. For more info on color rendering check this thread.
Strobe alternates between 6.8 and 16.7 hertz.

The price difference between the Klarus G30 and Nitecore EC4SW is not large if you buy them on a sale. Where the Nitecore shines, is the size. It has an ingenious two cell format and feels much more comfortable in the hand. The Klarus is 13,3 cm long vs. Nitecore’s 15 cm. Neither are really pocketable unless you’re wearing a winter coat. Tint between the lights is almost exactly the same and very neutral and smooth, although the CRI is not very high. The good tint makes up for a lot though. Output wise the Klarus manages to pass the Nitecore. In my styrofoam integrating sphere, I measured lumen output at 1760, which is 9 % higher than the Nitecore’s. Beam is tad tighter with 30 % more output in the middle of the beam. Runtime was not tested. There is no PWM on any mode. Unlike the direct driven Nitecore, the Klarus is regulated even on Turbo. There’s temperature regulation though, so if the light gets hot, the output decreases. The Nitecore also has a very effective temperature control.
