Hello again, I have recently come to own a brand new Insight HX120 and a HX150. I got the pair for free. So far I have really enjoyed the HX120. I havent even opened the HX150 yet, its still in the packaging. Anyway, I searched the forums here for any information on them and could not really find anything. I did find an old post about the Insight Arcturs (or something like that). So far I have not had any problems, have only had it about a week or so. I like the UI. I was wondering if I could put a rechargeable CR123 in the HX120? I would also like to know if a 18650 would fit/work with the HX150? Does anyone have any experience with these? When I open the 150 I can post some pics/beam shots etc. Any info would be awesome. Thanks
