Re: Advancemart 0.5 Watt 2 Level AA TM-317X Opini
I got mine because: it had a good, strong lanyard attachment; I liked the 1AA 0.5 W format; and there was a J2LED twofer deal where it cost only a dollar more than the TM-313. Workmanship is good. It's brightness is about equal to TM-311 and TM-313 levels (i.e. underdriven 0.5 W), and the color is pretty good - white with a little blue.
The only disappointing thing is the power drain on the low setting. According to
Craig, the low setting on this light puts out 1/3 the light of the high setting but it STILL draws 2/3 the current which means you might as well only have 1 brightness level (like the TM-313X) for all the good it does. I haven't done any runtime tests to confirm the current drain at low, but I see no reason to doubt Craig's measurements.
The light is good on high but - if I didn't need the solid lanyard attachment - I'd probably go for the TM-313 due to its smaller size.
