Summary
The Nitecore EDC23 flashlight has been my everyday companion for a few months. The Nitecore EDC29 is the perfect alternative when more light is needed. The two UHi 20 MAX LEDs are not only quite bright at 6500 lm, but also produce a wall of light in Lumin Shield mode. I also like the great UI with two buttons and the “Rapid Lock” lockout using a slide switch.
Given the compact design, it is not surprising that the flashlight heats up quickly and cannot maintain the high brightness for long. In the lower levels however, the constant current driver keeps the brightness pretty constant. Unfortunately it is not possible to choose freely between the wide and narrow beam for each brightness level. The permanently installed rechargeable battery can also be seen as a disadvantage.
The form factor kind of reminds me of my old EC4SW, which is a 2x18650 side by side flashlight with a Cree MT-G2 (big LED, pretty dated by today's standards).
How is the beam shape? The EC4SW is pretty floody for a reflector based light, which I personally prefer.
It can be both, thanks to the UHi 20 MAX. The main limitation is that the selection of flood/throw is linked to the brightness level.
That's cool! I will have to dig up beam patterns, not that I really need another light...
