Same issue with my g2x pro. Also used to experience this occasionally with my e1b. Standard affair w surefire and it'll and thrunite and limintop.
I'm wondering if the g2x pro might be a different issue, there were a vast number of posts about its sensitivity to bumps etc, where the positive terminal of the cell would momentarily lose contact with the front of the light, interrupting the circuit and fooling the light into a mode change. :shrug:
It makes me feel better to know that this is just a "feature" of my light. This is the first multi mode Surefire clicky I've owned. I would not have expected them to have a flaw in thier design. So much so, that I am wondering if this is by design?
IMO it's unfortunate with regards to the specific E1B software, perhaps a slight adjustment to the mode change timing would have minimized this behavior.
When you arms get fatigued, and your hands start to shake, you could accidentally "double tap" a switch when you only want to press it once. I could see military types getting upset with lights coming on in the wrong mode in high fatigue high stress situations.
From what I can tell, this light is more along the lines of the non-tactical crowd, serious use = single mode lights, but again, that's just my opinion after what I've read on CPF.
Or maybe I'm just making up excuses for my favorite light manufacturer.
LOL, well we're in the same boat, I myself am a late-adopter so I just try to read a lot to see what SF's I'll like and which ones that I won't.
I was tempted by the E1B a few times but decided against it based on reports about its UI - I ended up in the L-series camp instead. The nice thing about SureFire having a wide range of products is that everyone has a good chance of finding what works for them. For me, the only multimode SureFires I like are the
L1-series.
Best regards,
