xmas presents.
im thinking a single mode 40 lumen light for $12??
AAA.
A quick demo and including the instructions should be enough, anything more could be seen as condescending and an insult to the recipient's intelligence.
Get the 3-mode maratac/itp.
Medium will be fine for 99% of their needs. If you think they can handle knowing about the other modes, show them how it's done, but be prepared to show them again in a month or so.
That's my plan, anyways. Two of my intended recipients will get it right away and might actually use all 3 modes. The others, I'm not so sure, but with Medium being the first mode, it's okay if they forget the light has 2 other modes.
