i have a few minimags, old inc. converted to led with tle 5 iirc, 140lm(claimed), also have new mini mag led with multimode stock switch .
tle drop in is big improvement compared to stock incandescent mag, but next to new rebel minimags, it is not that good, i use iq switch, and i'm pretty happy with it.
after buying rebel mini mag, i gave old converted mag with iq to my father he likes it a lot, i think i turned him into flashaholic,
about 7-10 years back i bought a tail switch that was totally covered with rubber, looked like a cone, worked great, i never seen one like that since than.
