Re: I want one more MiniM*G mod. Opalec or Inretec
I'm anti-Mag these days because of their use of bogus legal intimidation against other light makers, so that colors this response. I don't care much for Minimag mods any more. The Minimag is heavier and clunkier than a 2AA light needs to be.
If you want a small unregulated LED light with Opalec-level output, try a PT Attitude for 15 bucks or so. It's powered by four AA's, has three LED's and supposedly has decent brightness for around 8 hours (similar to Opalec) followed by a long, dim trail-off period. It's maybe half the weight of a Minimag.
If you want two AA's and regulation, you could try a PT20 with the PT Matrix bezel (sold separately for around $25). That has three LED's like the Attitude but I don't know about the brightness.
For more brightness, try an Arc LS with the 2AA tail (more solid than a Minimag with a Luxeon pill).
No offense to Inretech but their device really wants L91 lithium AA cells and I think depending on those is a dumb idea. If you want a lithium powered light, you may as well use 123's instead of L91's. At recent low prices ($1-$1.25 per cell), 123's will cost much less per unit energy (or runtime hour at the same brightness) than L91's. So rather than a Minimag and Inretech, I think you're better off with an Arc LS and 1x123 pack. It's a much smaller and nicer light. You will have to change batteries more often, but it's a $1 battery change instead of a $4 change.
