I have one, and I like it. I don't think it has sold well because:I think this is the primary reason it hasn't sold well.
1. How much call is there for a keychain light that is as big as this one and uses CR123As?
2. How many people really need an infinitely variable brightness light of any size, as cool as this is? (And it is WAY cool.) My guess is that most people have no clue how to effectively use this because not many people practice seeing in the dark. (If you crank it up to the max brightness everytime you turn it on, it is a complete waste of money to own this light.)
3. Price. For a backup light that serves no specific specialized purpose that I can discern, this light is expensive. (Keep in mind I say this with love - I really love my T1A and use it all the time.)
4. <CPF Only> Other than the very low-low, floodiness, and a slight size advantage, the HDS lights are superior to this light. I would venture that from the perspective of most CPF'ers, the HDS lights are way better. They are certainly less expensive. (I also carry an HDS light - it is superb. Actually, the two lights complement each other pretty well - having a tiny flood light and a tiny throw light is kind of handy sometimes...)
5. <everyone else in the universe> the E1B is more affordable, and while less flexible, is likely a better choice as a backup for every LEO, and perceived as a better choice by dang near everyone else. The E1B is an awesome light - they compete with themselves on this one. (BTW, I hate the E1B, I also have one of those - just not for me - but I can appreciate that it is very well designed and awesome. It is also totally unsuitable for your purpose.)
BTW, lest anyone think that I am bashing the T1A - I really, really love this light. If it cost $150, I'd think it was a good deal, and at < $100 I'd give one to everyone I know... At $250 - it is expensive in my opinion. On the other hand, it is superbly well made, functions flawlessly, and is a joy to use.
I want to know if at a very low out-put, the light on the T1A is even (no rings or bright spots, etc), i.e., a true flood a low levels. And how 'warm' is the light, really?
The beam is an even flood light - and this has the lowest low of any light I own, which is a big part of the reason I really like it. It is usable for navigation with dark adapted vision. I haven't tried reading with it, although I'm sure you could - at least as well as you can read anything with dark adapted vision. You will not have a problem with it being too bright. As for warmth - it is a cool / neutral beam, with emphasis on cool, like Brasso said. (I'm being nice - it is quite cool, not as bad as a 5mm LED, but it is definitely a cool tint.)
