I think the Skilhunt UI is the most user friendly choice for a newbie.
I recommend teaching them to use Physical Lockout.

Received this Skilhunt H150 V4 with the new Buck Boost Driver that promises to be more efficient, with more constant output, cooler running, and with higher maximum output than the previous version.
The 5000K color temperature and neutral tint are excellent for a task light. The beam has nice...
I hope you enjoy the KR1AA clip option.
Fwiw Vaseline does not conduct electricity.
But it will probably get scraped out of the way from the pressure of closing the tailcap. No harm in trying.
good idea..
a copper washer would work too,
if you figure out what size works, please share info
I dont have either of those things, but I do have solder wick ;-)
good warning.. might be prudent to put a bit of solder on the ends of the solder wick, so they dont fray.
It is still in the testing phase, but the solder wick spacer and KR1AA clip are working so well, Im inclined to keep them installed.
Im keeping the tail closed and changing batteries...
thank you for explaining how things work for you in Europe
Im very lucky here in USA

Here are the Cliff Notes:
"Conclusion
To improve this driver, Zebralight needs to:
* get rid of low modes visible flicker
* Get rid of the ~400~1000Hz Riple by increasing the PWM control signal frequency
* fix the low modes...
Note that on early versions of the D3AA the O ring sits lower. Newer versions have the O ring sitting higher, leaving plenty of room for the clip, and the O ring remains completely covered by the tailcap:
yes, it goes on easily, and there is enough room to fit the top of the clip over a jeans seam, snugly..
easier to slide all the way into the upper bend of the clip with slacks that have thinner material than jeans.. but both materials work fine
