Re: So tell us what you think about your TK41
I received mine yesterday. Overall, it's a very nice light - machining is top-notch. Now, as one poster brought up in another thread, the battery holder feels cheaper on the TK41 than on the former TK40 (which I've never owned). That said, I don't think the battery holder is going to be a problem down the road. So far as tint in my sample, in the lowest mode the hot spot has this greenish hue to it, then on the second mode up, the hot spot has more of a pure white tint, while the corona has a greenish hue to it and then all other modes are pure white.
Now, so far as I'm concerned, here's the interesting part :
Yesterday evening I took both my M3C4 and TK41 outside for long distance beam comparisons. Now, I want to mention that it was drizzling, so this is by far not the best weather condition for outdoor beam comparisons. I took them out to an open field and was aiming them at a cluster of large trees - I can't tell you exactly how far are those trees though, but that was clearly a respectable distance. My brother-in-law who was also present during testing first said he didn't think there was any real difference between the two lights, but he's not a very detail oriented guy. Shining both at the exact same spot, I've noticed that there seemed to be a slight edge to the M3C4. I don't think that the M3C4 throws any further than the TK41, but I've noticed that the M3C4 illuminated the target a tiny bit more, allowing you to see more of what was being illuminated.
Then when I came home from my sister-in-law's I compared those same two lights once more, standing on my deck shinning them at another relatively distant target (yet another cluster of tall trees). From my deck, I have a clear view of some nice distant targets. I picked out one such target and proceeded to aim each light at said target. My girlfriend was next to me for the whole time. We both noticed how we could make out a little more of that cluster of trees in the distance - the difference wasn't night and day, but enough for us to notice. I then took a break so our eyes could rest and did it over - the outcome was the same.
The beam of the M3C4 seemed whiter than that of the TK41 at that distance and I think this is why it caused us to see more of what we shined it to. The reflector on the M3C4 looks like it's a tiny bit deeper, but we're talking by a very small margin here and but both reflectors when held up head to head are the same diameter.
That said, when I took turns shining those two lights at a closer target (someone's backyard shed), I seemed to have noticed that the TK41's beam appeared to be more intense.
Of note : on my first outdoor comparison of the M3C4 and TK41, the target was barely illuminated by either light - worded differently, it was so far away a target that we're clearly not talking usable/effective range - I wouldn't have been able to spot an animal at that distance, except perhaps it's eyes.
I'll perform the same test when the wheather clears and should I find a different outcome, I'll make the needed corrections - so let's just say this is a preliminary comparison.
