right as a keychain light!

I have long back and forth creates what it for now is to be a key lamp. The first thing I came lamps with 16340er battery to mind that are well lit but unfortunately also significantly thicker than a AAA-lamp. "Perhaps you would prefer an AA lamp and a little more lumens than a AAA-lamp" was the next consideration. Ultimately, I'm stuck with the ThruNite Ti2 due to the yet smaller dimensions. Convinced have me:

1. The two lighting modes (81lm for AAA lamp is properly and for your key ring with me more than enough; 3lm are very pleasant when the eyes have adjusted to the darkness).

2. The housing shape (cylindrical simply - and with only 72mm x 14mm it does not interfere in your pocket).

3. The price (by 15 it has become / money to my price).
