~ (late to the Review party, but here to share my delight in .04 lumen use)
ThruNite "Ti", (tiny) 2 level 'AAA' (aluminum) light with 0.04 lumen Low.
I will give my summation first ,
This is now my favorite Low Level "Firefli" , Round-thu-house NeckLight .
My overall impression of the "Ti" is very good. It was designed by ThruNite to be a "Firefli" low level key-chain light. It is also very useful as a lanyard neck light . I was very skeptical of this light when it first came out , since I was not familiar with what 0.04lumens looked like . I did not think it would be bright enough for me on Firefli mode , BUT ... I have since changed my mind . Now that I have one I can say that it truly is bright enough for covert nighttime operations. The .04 lumen beam does reach across the room and keep you from tripping on the Cat .

Construction & Feel
It is a little larger than most other 'AAA' twisties , but that makes it easier to hold and operate with one hand if you have arthritis in your joints and swollen/knotty knuckles . The knurling provides just the right amount of grip and the brass threads contribute to the buttery smooth turning of the head . I also found out it can be used as 'Momentary' if you set it close to the turn-on point and then press laterally on the head with your thumb or finger . The internal mode switching 'Tab' may have to be carefully adjusted at times by the user as it gets compressed with use . The anodized finish seems to be done well and I like the attachment lug being centered so the light hangs straight. It won't tail-stand , but it was intended as a hanging light , on a keychain. And don't be confused by the "Ti" name they gave it ... it is actually an aluminum body light .
Beam & Tint
The R-4 produces a smooth beam and what I call a "Creamy" white tint . I would have preffered a whiter R-2 .... but that's just my preference. On 'Hi' it will light up the entire width of a door at a distance of 9 feet . On "Firefli" mode there is not much "Sidespill" light , but you can't expect much of that at .04 lumens . The central spot has to do, which is 1 foot in diameter @ 3 feet from a wall . This light's low level will be good for reading menu's or maps without disturbing others . The Hi level is bright enough to be a good secondary EDC . ThruNite says it has a Max lumens of "60" ... but to me the Hi compares to the Medium setting of a Q-mini AA , which is stated to be "25" lumens ... so I think the "Hi on the Ti" ... is somewhere around 30 to 40 lumens .. just my guess. (maybe the Qmini figures are wrong?)
U.I. & Battery
The continual one-direction twist is much easier to use (especially one handed) as a key-chain light . Much easier than ... twist-untwist-twist-untwist ... and makes for a good inexpensive loaner light too. They won't even notice the first level. Tell em just twist - and it's ON at the level they will expect . Run time on common batteries should be acceptable and since the use of 4.2v Li-Ions is NOT mentioned in the specs by ThruNite ..... I would advise against it.
I think this is a good value at $16.00 and is just what the Low-level crowd has been wanting. It IS very useful .The Hi level should be left as it is . Additional lights at 2 to 4 lumens will be welcomed as well . I would like to see a whiter R-2 version offered - but let's face it - at this size of light ... when you need light , any tint will do . I DO like this light and would recommend you add it to your collection . Craig had a good marketing strategy when he 'Torture Tested' a "Ti" light , and posted pic's & details of it . It makes me more confident that it will last as long as I expect it to .
Sorry for no pic's , but I don't do pic's well , and there are so many good ones already, it would be redundant .
More to be added later ...... as I use it and develop more comments .
EDIT ... side note ... EXPERIMENTATION ,
See post #14 for details ....
If your tab does break off , a square of QTC material inserted where the tab was .... may bring it back to life ... Per 127.0.0.1 in post 14.
